HHT Hazardous Area Humidity Transmitter

HHT Hazardous Area Humidity Transmitter

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
