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). Sensor should be replaced annually or sooner depending on application conditions.
