TILLQUIST Sensor Spare Parts

A sensor is a device that receives signals or stimuli and responds, capable of converting the measured physical or chemical quantity into another corresponding output. Used for automation control, security equipment, etc. In stimulus theory, electronic stimulation devices are often used during this period to obtain electrical stimulation.

A device that has been used for a long time is an induction coil, but it is no longer widely used here and is mostly replaced by vacuum tubes and semiconductor stimulation devices.

The definition of sensors in the national standard GB7665-87 is: 'devices or installations that can sense the specified measured object and convert it into usable signals according to certain rules.'

24GHZ microwave radar sensor

It is usually composed of sensitive components and conversion components. A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules, in order to meet the requirements of information transmission, processing, storage, display, recording, and control. It is the primary step in achieving automatic detection and control.

A 'sensor' is defined in the New Wei Dictionary as a device that receives power from one system and typically delivers it in another form to a second system.

According to this definition, the function of a sensor is to convert one form of energy into another, so many scholars also use the term 'transducer' to refer to 'sensor'.

The influence of the input of a sensor on its output is called the sensing coefficient. For example, a mercury thermometer has a sensing coefficient of 1 cm/° C if the mercury column rises by 1cm every time the temperature rises by 1 ° C.

When the input and output of a sensor form a linear relationship, the sensor is an ideal sensor. Meanwhile, ideal sensors should also adhere to the following principles:

1. Only affected by the tested factors;

2. Not affected by other factors;

3. The sensor itself does not affect the measured factors.

Folding temperature sensor

Temperature sensors are generally electronic components that convert temperature into electronic data. A temperature sensor made of a conductive material with resistance changing with temperature. It is an element (Pt100) that uses platinum and has a resistance of 100 ohms at 0 ° C. Semiconductor temperature sensors generally integrate amplification and adjustment circuits. The oscillation frequency of a crystal oscillator varies with temperature, making it possible to measure temperature very accurately.

Thermocouples that use thermoelectric effects to measure temperature have a surface charge density that varies with temperature, making their surface charge intensity suitable for measuring temperature.

Folding pressure sensor

A pressure sensor is a sensor used to measure the pressure of liquids and gases. Similar to other sensors, pressure sensors convert pressure into electrical signals for output during operation.

pressure sensor

Pressure sensors are widely used in many monitoring and control applications. In addition to direct pressure measurement, pressure sensors can also be used to indirectly measure other quantities such as liquid/gas flow rate, velocity, water surface height, or altitude.

There are significant differences in the technology, design, performance, working adaptability, and price of pressure sensors used. Conservatively estimated, there are over 50 types of pressure sensors and at least 300 companies producing pressure sensors.

Meanwhile, there is also a type of pressure sensor designed for dynamically measuring rapidly changing pressure. Examples of applications include monitoring the combustion pressure of engine cylinders or the pressure of gases in turbine engines. Such sensors are generally made of piezoelectric materials, such as quartz.

Some pressure sensors, such as those used in traffic cameras, operate in binary mode, meaning that when the pressure reaches a certain value, the sensor controls the circuit to turn on or off. This type of pressure sensor is also known as a pressure switch.

Folding image sensor

An image sensor is a device that can convert visual images into electronic signals, mainly used in digital cameras and other imaging devices. It is generally composed of a set of CCD or CMOS sensors (such as active pixel sensors).

image sensor

Color image sensors can be divided into the following categories based on their ability to distinguish colors:

Bayer sensor, an inexpensive and most common image sensor, uses a Bayer filter to make different pixels only sensitive to one of the three primary colors of red, blue, and green. These pixels are interwoven together and then restored to the original image through demosaicing interpolation;

Foveon X3 sensor, used for certain Sigma and Polaroid digital cameras. Each pixel of it has triple sensors that can sense all colors;

3CCD sensors, such as some Panasonic digital cameras, use dual color prisms for light splitting and employ three independent CCD sensors, which are generally considered for image restoration but are relatively expensive.

Folding Hall Effect Sensor

A Hall effect sensor, also known as a Hall sensor, is a transducer that converts changing magnetic fields into changes in output voltage. Hall sensors are primarily used to measure magnetic fields, and can also be used to measure physical quantities that generate and affect magnetic fields, such as proximity switches, Hall multipliers, position measurements, speed measurements, and current measurement devices.

Its form is that the sensor acts as an analog transducer and directly returns a voltage. Under a known magnetic field, its distance from the Hall disk can be set. By using multiple sets of sensors, the relevant position of the magnet can be inferred.

Hall Effect Sensor

The current passing through a conductor generates a magnetic field that varies with the current, and Hall effect sensors can measure the current without interfering with it. Typically, it is integrated with a winding core or a permanent magnet next to the tested conductor.

Usually, Hall effect sensors are connected to circuits, allowing devices to operate in digital (on/off) mode, which can be referred to as switches in this case. Common equipment in industry, such as cylinders, are also used in daily equipment; Some printers use them to monitor paper shortage and open cover situations. When high reliability is required for keyboards, they are also applied in keyboards.

Hall effect sensors are commonly used to measure the speed of wheels and axles, such as on internal combustion engine ignition timing or tachometers. It is used in brushless DC motors to detect the position of permanent magnets. The wheels in the diagram have two equal parts
