hht系列本安型温湿度变送器
产品介绍
the series hht hazardous area humidity/temperature transmittertakes accurate measurements in the harshest of environments. thetransmitter is offered in explosion-proof and intrinsically-safeversions depending on the application's requirements. theexplosion-proof model is offered with 4 to 20 ma output forhumidity only. the intrinsically-safe version is offered with 4 to20 ma output for humidity and temperature. both versions have anoptional two line alphanumeric display to show the current humidityand temperature.
the series hht humidity/temperature transmitter is excellent foroffshore hvac applications, dust and grain applications.intrinsically safe models require an intrinsically safebarrier.
