Pipe Temperature and Humidity Sensor Transmitter Industrial RS485 0-2V 0-5V 0-10V 4-20MA Output High Precision DC10-30V

Product Manual:

The relative humidity of air is the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature. The value is a percentage. (that is, the amount of water vapor in the air at a given time as a percentage of the saturated water vapor at that temperature) , expressed in Rh.

Air temperature and humidity sensor using imported digital temperature and humidity sensor, production has been fine calibration, calibration data stored in internal memory. The relative humidity and temperature sensors have the characteristics of digital output and full interconversion, and do not need to go through complex calibration process, it excels in measuring accuracy, linearity, repeatability, interconversion and consistency. It is suitable for environmental equipment, equipment integration and general environmental testing.

(1) high cost performance, wide voltage design.

(2) digital linearization correction, high accuracy and high stability.

(3) full range temperature and humidity compensation with wide measurement range and optional measurement range.

(4) flexible installation and convenient use.

(5) small size, light weight and anti-vibration.

(6) can be made into a variety of shapes, convenient for different customer needs.

Widely used in building automation, telecom room, paper, warehousing logistics, shopping malls, hotels, cinemas, railway stations, museums, theaters, agricultural greenhouses, hospitals, meteorology, clean workshops and other areas need to measure air temperature and humidity.
