The HS-RXXXMP Series are stainless steel wall plate relative humidity transmitters. They use a field-proven ca¬pacitive type humidity sensor and microprocessor temperature compensation for reliable, accurate measurement of indoor humidity. The wall plate sensor is perfect for locations requiring periodic wipe down as it features a 304 stainless steel plate with a neoprene gasket. The sensor is protected by a 100 micron sintered stainless steel filter. The plate sensor is available with either 4-20 mA or 0-5 Vdc or 0-10 Vdc output signal types and the transmitter is located on the back of the plate for ease of installation.
