Series HHT Hazardous Area Temperature Transmitters
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. It is important to develop a routine schedule for replacing the RH/temperature sensor (part number A-451). The sensor should be replaced annually or sooner depending on application conditions.
- FM approved explosion-proof and intrinsically safe models
- Integral LCD option
- Replaceable calibrated sensor for long term use in harsh environments
- Dual temperature and relative humidity output models
