HTX HVAC Series Humidity-Temperature Transmitter
Brand: Intempco Controls, IncThe INTEMPCO HTX series humidity transmitters offer high accuracy, low cost humidity, and temperature measurement that can withstand tough industrial and HVAC applications.
The rugged solid state sensor has high chemical contamination resistance and handles extreme ventilation conditions, like swimming pool environments, with ease. Even water immersion of the sensor will not damage it.
Features- Low cost
- On-board zero and span adjustments
- Rugged design using solid state sensors
- High accuracy (±3% over 0 to 90% RH standard)
- 2-Wire, loop-powered operation (4-20 mA output)
- Temperature compensated humidity measurement
- Factory calibrated (0 to 100% RH standard, custom ranges available)
- Integrated loop-powered temperature transmitter available
