The sensor provides accurate long term repeatability and high reliability performance for process control and energy management. The instrument is powered by 24 Vdc or optional AC universal supply 85 to 230 Vac. The RHCM-40 series uses the chilled mirror dew point temperature condensation principle to determine the water vapor concentration in gas mixtures, and a platinum resistance RTD to accurately measure that temperature. Options include air temperature and humidity measurement. There are two selectable analog outputs which include 4 to 20 mA, 0 to 5 Vdc, or 0 to 10 Vdc and an RS232 serial port as well as electrically isolated relay contacts. Range: Dew Point (Standard): -40 to 60°C (-40 to 140°F) Air Temperature (Optional): -40 to 60°C (-40 to 140°F) RH (Optional): 1 to 95% Accuracy: ± 0.2°C for both dew point and temperature Hysteresis: Negligible Repeatability: ±0.05°C Response: 1°C/second not including settling time Flow Rate: Static to 3000 linear feet/minute Pressure: 100 psig maximum (higher pressure available on special order) Analog Outputs: 2 analog ouputs (4 to 20 mA/0 to 5 Vdc to 0 to 10 Vdc selectable) Load: 4 to 20 mA: 0 to 250 Ω 0 to 5/10 Vdc: 1 kΩ or higher Relay Outputs: 2 programmable alarm relays K1: Clean mirror/Alarm 1 K2: Servolock/Alarm 2 Contact Rating: Normally open (NO) 3 A at 25 Vac, or 30 Vdc RHCM-40-PL-P shown smaller than actual size.
