HHT系列本安型温湿度变送器
产品介绍
The Series HHT Hazardous Area Humidity/Temperature Transmittertakesaccurate measurements in the harshest of environments.Thetransmitter is offered in explosion-proof andintrinsically-safeversions depending on the application'srequirements. Theexplosion-proof model is offered with 4 to 20 mAoutput forhumidity only. The intrinsically-safe version is offeredwith 4 to20 mA output for humidity and temperature. Both versionshave anoptional two line alphanumeric display to show the currenthumidityand temperature.
The Series HHT humidity/temperature transmitter is excellentforoffshore HVAC applications, dust and grainapplications.Intrinsically safe models require an intrinsicallysafebarrier.
