Sensor with displaying function

Feature & Application:

for Duct Mounting

Sensor without displaying function

Full Temperature Compensation

2 wire output       Accuracy of humidity +-2.0%

Accuracy of temperature +-0.2Celsius     

Range 0 to 100% RH,  -40~100Celsius

Light weight, easy installation

Our temperature compensated humidity transmitter has been designed to meet the demand of energy-care, environmental protection, including air quality control.

The capacitance element based sensor is one of the most stable sensor available and no recalibration required.

The 2-wire design provides an easy installation, decreasing cost of field wiring .

The high humidity accuracy cover full range from 0 to 100% RH,  allowing precise measurement of the humidity over the operating temperature from-40~80 Celsius. Even condensation on the sensor will not harm it.

Each transmitter is calibrated in our computer operated atmospheric simulation chamber.
