2% and 3% RH Room Combo Wall Plate Sensor
NSA-3PCT-RH

Part Numbers

NSA-HH/RH3-CP-SP-010-C
NSA-HH/RH2-CP-SP-010-C

The Carrier Relative Humidity with Thermistor Wall Plate Series utilizes a thermoset polymer capacitive sensing element with a factory applied hygroscopic filter to deliver a proportional analog voltage output signal. The hygroscopic filter provides added resistance to moisture, dust, and other chemicals for greater long term reliability. The RH Stainless Plate transmitter features integral DIP switches for field selection of the proper output signal and supply voltage to meet your applications requirements. Each unit also contains 0%, 50%, and 100% test options to verify that the transmitter is both working and properly installed.
