Hazardous Area Humidity and Temperature Transmitter (Series HHT)

Hazardous Area Humidity and Temperature Transmitter (Series HHT)

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
