Series HHT Hazardous Area Humidity/Temperature Transmitter

Intrinsically Safe or Explosion-Proof Models

The Series HHT Hazardous Area Humidity/Temperature Transmitter takes accurate measurements in the harshest of environments. The explosion-proof model is offered with 4 to 20 mA output for humidity only. The intrinsically safe version is offered with 4 to 20 mA output for humidity and temperature, and do require an intrinsically safe barrier to meet hazardous area approvals.

Product Applications

Process monitoring
Offshore HVAC monitoring
Dust and grain handling

FM approved explosion-proof and intrinsically safe models
Integral LCD option
Dual temperature and relative humidity output models
