Dwyer RHPLC-2N11 is a humidity/temperature transmitter with a drift of <0.25% RH/year. It operates in a temperature range of -40 to 140°F (-40 to 60°C) and requires a power supply of 10 to 35 VDC for 4 to 20 mA or 0 to 5 VDC output. It has a response time of 8 s (π63) and features a capacitive polymer sensor. The housing is made of polycarbonate and it comes with a screw terminal block for electrical connections. Accuracy for temperature sensors is ±0.3°C @ 0°C and ±0.36ºF @ 77°F for the RTD and passive thermistor sensors, respectively. For humidity, accuracy is ±2% 10 to 90% RH @ 25°C.
