Relative humidity and temperature transmitter
HTW2000
Henan Hanwei Electronics Co.,Ltd
Model HTW2000， without display, accuracy 3%,
Feature & Application:
for Wall Mounting
Sensor with displaying function
Full Temperature Compensation
2 wire output Accuracy of humidity +-3.0%
Accuracy of temperature +-0.5Celsius
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.
Technical Specification:
Power supply 12~24V DC
