Overview
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. Field calibration can be performed by using the
increment and decrement calibration DIP switches without the need to replace the
sensing element. These enhancements provide increased flexibility and outstanding
long-term reliability. All RH Stainless Plate transmitters come standard with an attractive brushed finish stainless steel,
single gang wall mounting plate and are designed to mount over a single gang junction box in the wall. The PCBs are
conformally coated for added protection from moisture and other contaminants. A temporary plastic sensor cover is
included to provide protection for the RH sensor from chemicals used in wash down applications.
Applications: Pharmaceutical, Hospitals, Operating Rooms, Vivariums, Clean Rooms, Process Control, Wash Down
Environments & Stability Chambers
