Greystone RH100S02I20DTP S/S Surface Humidity Transmitter, 2%, 4-20mA output, 10,000, type 3, NTC Thermistor, ±0.2°C, Tamper Proof Screws

Greystone RH100S02I20DTP is a stainless-steel wall-plate relative humidity transmitter for indoor RH measurement. It uses a thermoset polymer-based capacitive sensor with temperature compensation to measure 0-100% RH, with +/-2% RH accuracy over 5-95% RH. This model provides a 4-20 mA current-loop humidity output.

Configuration: optional direct temperature sensor: 10,000 ohm Type 3 NTC thermistor, +/-0.2 C with 2-wire resistance output; tamperproof screws included. The 304 stainless-steel plate includes a neoprene gasket and a 100 micron sintered stainless-steel sensor filter, and mounts directly on a standard electrical box.

For periodic cleaning, follow the installation instructions. Before washing the area, protect the sensor filter with the supplied plastic cap to prevent spray entering the sensor.
