Dwyer RHPLC-3N2A is a humidity/temperature transmitter with a drift of <0.25% RH/year. It has a temperature range of -40 to 140°F (-40 to 60°C) and operates on a power requirement of 10 to 35 VDC for 4 to 20 mA or 0 to 5 VDC output. The response time is 8 seconds (π63) and it utilizes a capacitive polymer sensor. The transmitter has an accuracy of ±2% 10 to 90% RH @ 25°C for 2% accuracy units and ±3% 20 to 80% RH @ 25°C for 3% accuracy units. Its enclosure is made of polycarbonate and it features screw terminal block electrical connections. Accuracy for RTD temp sensor is ±0.3°C @ 0°C (±0.54°F @ 77°F), accuracy for passive thermistor temp sensor is ±0.36ºF @ 77°F (±0.2°C @ 25°C), and accuracy for current/volt temp output is ±0.9°F @ 77°F (±0.5°C @ 25°C). The transmitter has a repeatability of ±0.1% and hysteresis of ±0.8%.
