1overview
The control of humidity in industrial processes is becoming increasingly strict, and our company's resistive humidity sensor, with its * * temperature and humidity resistance, can-70—260A wide temperature range of ℃ and1%---98%RHWithin the humidity range, it ensures high precision, long-term stability, service life, and superior repeatability for temperature and humidity measurement in process environments, becoming the most cost-effective product in this field. The importance of temperature and humidity measurement in industrial production and experimental processes is highlighted in the areas of high-temperature drying and aging of products, low-temperature and high humidity experiments, and storage. Widely used for temperature and humidity measurement and control in industries such as dryers, kilns, meteorology, environmental protection, cement maintenance, electricity, desulfurizers, pharmaceuticals, textiles, chemicals, metallurgy, feed, food, batteries, low-temperature and high humidity storage, wood, and wine industry.

4、 Installation steps:
1Probe usedM27*2The installation thread or outer diameter is
2Connect the transmitter cable to the acquisition device.
Installation position:
1The transmitter should be placed vertically as much as possible, and during installation, ensure that the sensor is on top of it
The font should be in the positive direction to ensure that the sensor is located below the transmitter;
2The installation height is the height of the human body sitting or the main environmental area that requires measurement
Installation precautions:
1Avoid generating temperature in areas that are easy to transfer heat and directly affect the test area
Installation in poor areas may result in inaccurate temperature and humidity measurements.
2Install in a stable environment area. Avoid direct sunlight, stay away from windows, air conditioning, heating and other equipment, and avoid facing windows or doors directly.
Fiveuse
1Carefully check and ensure that the wiring is correct before connecting itDC24VWhen measuring the power supply with a multimeter, the corresponding current or voltage will be measured Value.
2If you want to disassemble the transmitter, you must first disconnect the power supply and then proceed with the disassembly.
3This transmitter is an indoor type, and water should be avoided from entering the inside of the transmitter to prevent damage.
6、 Precautions
1Please read this manual carefully before use to ensure correct wiring. Any incorrect wiring may cause irreversible damage to the transmitter.
2Avoid generating temperature in areas that are easy to transfer heat and directly affect the test area
Installation in poor areas may result in inaccurate temperature and humidity measurements.
3Prevent direct damage to the sensor from chemical reagents, oil, dust, etc. Do not use it for a long time in environments with condensation or extreme temperatures. Do not use cold Thermal shock.
7maintenance
Long term use of the transmitter may cause drift. To ensure measurement accuracy, it should be calibrated once a year.
8Transportation and storage
1Try to avoid vibration and handle the transmitter gently.
2Long term storage conditions:
9、 Open box inspection
1. After opening the packaging, check if the transmitter is intact.
2. One transmitter, one instruction manual, and one certificate of conformity.
10、 Fault analysis and troubleshooting
1. When simulating output, if the transmitter output is0, or if the output value is not within the range, please check if the wiring is correct or secure Solid.
2. If it is not for the above reasons, please contact the manufacturer.
