temperature

Sensor (Figure 9)

Sensor (Figure 9)

1. Room temperature tube temperature sensor: Room temperature sensors are used to measure the ambient temperature indoors and outdoors, while tube temperature sensors are used to measure the wall temperature of evaporators and condensers. The shapes of room temperature sensors and tube temperature sensors are different, but their temperature characteristics are basically the same. According to temperature characteristics, Midea uses two types of room temperature tube temperature sensors: 1. The constant B value is 4100K ± 3%, and the reference resistance is 25 ℃, corresponding to a resistance of 10K Ω± 3%. The resistance tolerance at 0 ℃ and 55 ℃ is approximately ± 7%; For suppliers below 0 ℃ and above 55 ℃, there may be certain differences in resistance tolerances. The higher the temperature, the smaller the resistance value; The lower the temperature, the greater the resistance. The further away from 25 ℃, the larger the corresponding resistance tolerance range.

2. Exhaust temperature sensor: The exhaust temperature sensor is used to measure the exhaust temperature at the top of the compressor, with a constant B value of 3950K ± 3% and a reference resistance of 90 ℃ corresponding to a resistance of 5K Ω± 3%.

3. Module temperature sensor: The module temperature sensor is used to measure the temperature of the frequency conversion module (IGBT or IPM). The model of the temperature sensing head used is 602F-3000F, and the reference resistance is 25 ℃, corresponding to a resistance of 6K Ω± 1%. The corresponding resistance values for several typical temperatures are: -10 ℃ → (25.897~28.623) K Ω; 0 ℃ → (16.3248~17.7164) K Ω; 50 ℃ → (2.3262~2.5153) K Ω; 90 ℃ → (0.6671~0.7565) K Ω.

There are many types of temperature sensors, and the commonly used ones are thermal resistors: PT100, PT1000, Cu50, Cu100; Thermocouples: B, E, J, K, S, etc. Temperature sensors not only come in a wide variety of types, but also have diverse combinations, so suitable products should be selected according to different locations.

Temperature measurement principle: Based on the regular changes in resistance and thermocouple potential with temperature, we can obtain the temperature value that needs to be measured.

Wireless temperature

Wireless temperature sensors convert the temperature parameters of the controlled object into electrical signals and send wireless signals to the receiving terminal to detect, adjust, and control the system. It can be directly installed in the junction box of general industrial thermal resistors and thermocouples, forming an integrated structure with on-site sensing components. Usually used in conjunction with wireless relays, receiving terminals, communication serial ports, electronic computers, etc., this not only saves compensation wires and cables, but also reduces signal transmission distortion and interference, thereby obtaining high-precision measurement results.

Wireless temperature sensors are widely used in automation industries such as chemical, metallurgical, petroleum, power, water treatment, pharmaceutical, and food. For example, temperature collection on high-voltage cables; Temperature collection in harsh environments such as underwater; Temperature collection on moving objects; Difficult to connect and transmit sensor data through space; A data acquisition solution chosen solely to reduce wiring costs; Data measurement in workplaces without AC power supply; Portable non fixed location data measurement.

intelligence

Sensor (Figure 10)

Sensor (Figure 10)

The function of intelligent sensors is proposed by simulating the coordinated actions of human senses and brain, combined with long-term research and practical experience in testing technology. It is a relatively independent intelligent unit, which has reduced the strict requirements for hardware performance, and with the help of software, the performance of sensors can be greatly improved.

1. Information storage and transmission - With the rapid development of fully intelligent distributed control systems (SmartDistributed Systems), intelligent units are required to have communication functions and use communication networks for bidirectional communication in digital form, which is also one of the key indicators of intelligent sensors. Intelligent sensors achieve various functions by testing data transmission or receiving instructions. Such as setting gain, compensation parameters, internal inspection parameters, test data output, etc.

2. Self compensation and calculation functions - For many years, engineering and technical personnel engaged in sensor development have been doing a lot of compensation work for temperature drift and output nonlinearity of sensors, but have not fundamentally solved the problem. The self compensation and calculation functions of intelligent sensors have opened up new avenues for temperature drift and nonlinear compensation of sensors. In this way, relaxing the precision requirements for sensor processing, as long as the repeatability of the sensor can be guaranteed, using a microprocessor to calculate the test signal through software, and using multiple fitting and difference calculation methods to compensate for drift and nonlinearity, can obtain more accurate measurement results for pressure sensors.

3. Self checking, self calibration, and self diagnostic functions - Ordinary sensors require regular inspection and calibration to ensure sufficient accuracy during normal use. These tasks generally require disassembling the sensor from the usage site and sending it to the laboratory or inspection department for testing. If there is an abnormality in the online measurement sensor, it cannot be diagnosed in a timely manner. The use of intelligent sensors has greatly improved the situation. Firstly, the self diagnostic function performs self inspection when the power is turned on, and diagnostic testing is conducted to determine if the component has *. Secondly, calibration can be performed online based on usage time, and the microprocessor compares and verifies the measurement characteristic data stored in the EPROM.

4. Composite sensitive function - observing natural phenomena around, common signals include sound, light, electricity, heat, force, chemistry, etc. Sensitive component measurement is generally conducted through two methods: direct and indirect measurement. Intelligent sensors have composite functions and can simultaneously measure multiple physical and chemical quantities, providing information that can comprehensively reflect the laws of material motion.

photosensitive

Light sensitive sensors are one of the most common sensors, with a wide variety of types including phototubes, photomultiplier tubes, photoresistors, phototransistors, solar cells, infrared sensors, ultraviolet sensors, fiber optic photoelectric sensors, color sensors, CCD and CMOS image sensors, etc. Its sensitive wavelengths are around visible light wavelengths, including infrared and ultraviolet wavelengths. Light sensors are not limited to detecting light, they can also be used as detection elements to form other sensors that detect many non electric quantities, as long as these non electric quantities are converted into changes in light signals. Light sensors are one of the most widely produced and applied sensors, and they play a very important role in automatic control and non electric measurement technology. The photosensitive sensor [2] is a photoresistor that generates current when photons impact the junction.

biology

The concept of biosensors

Sensor (Figure 11)

Sensor (Figure 11)

Biosensors are an interdisciplinary field that combines bioactive materials (enzymes, proteins, DNA, antibodies, antigens, biofilms, etc.) with physical and chemical transducers. They are a detection and monitoring method for the development of biotechnology, as well as a rapid and trace analysis method at the molecular level of substances. Various biosensors have the following common structure: including one or several related bioactive materials (biofilms) and physical or chemical transducers (sensors) that can convert signals expressed by biological activity into electrical signals. The two are combined together and processed using modern microelectronics and automated instrumentation technology to form various usable biosensor analysis devices, instruments, and systems.

The principle of biosensors

The substance to be tested enters the bioactive material through diffusion, undergoes molecular recognition, undergoes biological reactions, and the generated information is then converted into quantifiable and processable electrical signals by corresponding physical or chemical transducers. After amplification and output by secondary instruments, the concentration of the substance to be tested can be determined.

Classification of biosensors

According to the classification of life substances used in their receptors, they can be divided into microbial sensors, immunosensors, tissue sensors, cell sensors, enzyme sensors, DNA sensors, and so on.

According to the principle of sensor device detection, it can be classified into: thermosensitive biosensors, field-effect transistor biosensors, piezoelectric biosensors, optical biosensors, acoustic biosensors, enzyme electrode biosensors, mediator biosensors, etc.

According to the types of interactions between biologically sensitive substances, they can be classified into two types: affinity type and metabolic type.

vision

Working Principle:

Sensor (Figure 12)

Sensor (Figure 12)

A visual sensor refers to the ability to capture thousands of pixels of light from an entire image, and the clarity and delicacy of the image are often measured by resolution, expressed in terms of the number of pixels.

Visual sensors have thousands of pixels that capture light from an entire image. The clarity and delicacy of an image are usually measured by resolution, represented by the number of pixels.

After capturing the image, the visual sensor compares it with the reference image stored in memory to make an analysis. For example, if the visual sensor is set to distinguish machine parts with eight bolts correctly inserted, the sensor knows that it should reject parts with only seven bolts or parts with misaligned bolts. In addition, regardless of where the machine component is located in the field of view, and whether the component rotates within a 360 degree range, the visual sensor can make a judgment.

Application fields:

The low cost and ease of use of visual sensors have attracted machine designers and process engineers to integrate them into various applications that once relied on manual labor, multiple photoelectric sensors, or no inspection at all. The industrial applications of visual sensors include inspection, metrology, measurement, orientation, defect detection, and sorting. The following are just some application examples:

At the car assembly plant, inspect whether the adhesive beads applied by the robot to the door frame are continuous and have the correct width;

At the bottling plant, verify that the bottle cap is properly sealed, the filling level is correct, and that no foreign objects fall into the bottle before sealing;

Ensure that the correct packaging labels are affixed in the correct positions on the packaging production line;

Inspect whether there are damaged or missing tablets in the bubble wrap packaging of aspirin tablets on the drug packaging production line;

At a metal stamping company, stamping parts are inspected at a speed of over 150 pieces per minute, which is more than 13 times faster than manual inspection.

displacement

Sensor (Figure 13)

Sensor (Figure 13)

Displacement sensors, also known as linear sensors, are sensors that convert displacement into electrical quantities. Displacement sensor is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electrical quantities. It is divided into inductive displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, and Hall displacement sensor.

In this conversion process, many physical quantities (such as pressure, flow rate, acceleration, etc.) often need to be converted into displacement first, and then the displacement can be converted into electrical quantity. Therefore, displacement sensors are an important type of basic sensor. In the production process, displacement measurement is generally divided into two types: measuring physical dimensions and measuring mechanical displacement. Mechanical displacement includes linear displacement and angular displacement. According to the different forms of transformation of the measured variable, displacement sensors can be divided into analog and digital types. Simulation can be divided into two types: physical type (such as self generating type) and structural type. The commonly used displacement sensors are mostly of the analog structural type, including potentiometer displacement sensors, inductive displacement sensors, self-tuning machines, capacitive displacement sensors, eddy current displacement sensors, Hall displacement sensors, etc. An important advantage of digital displacement sensors is that they facilitate the direct transmission of signals into computer systems. This type of sensor is developing rapidly and its applications are becoming increasingly widespread.

pressure

Pressure sensors are the most commonly used sensors in industrial practice, widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, power, ships, machine tools, pipelines and many other industries.

Ultrasonic distance measurement

The ultrasonic distance measurement sensor adopts the ultrasonic echo distance measurement principle, uses accurate time difference measurement technology to detect the distance between the sensor and the target, and uses small angle and small blind area ultrasonic sensors. It has the advantages of accurate measurement, non-contact, waterproof, anti-corrosion, low cost, etc. It can be applied to liquid level, material level detection, * liquid level, and material level detection methods to ensure a stable output when the liquid level has foam or large shaking, and it is difficult to detect the echo. Application industry: liquid level, material level, material level detection, industrial process control, etc.

24GHz radar

It adopts a planar microstrip antenna design and has the characteristics of small size, light weight, high sensitivity, and strong stability. It is widely used in industries such as intelligent transportation, industrial control, security, sports, and smart home. On November 19, 2012, the Ministry of Industry and Information Technology officially issued the "Notice of the Ministry of Industry and Information Technology on Issuing the Frequency of Use of Short Range Vehicle Mounted Radar Equipment in the 24GHz Frequency Band" (MIIT [2012] No. 548), which clearly stated that the use of short range vehicle mounted radar equipment in the 24GHz frequency band as a specification for vehicle mounted radar equipment
