Dwyer RHP-2O1D | OSA Humidity/Temperature Transmitter | ±2% RH, 4-20 mA RH, Pt100 RTD
With a 4-20 mA humidity output plus a passive Pt100 RTD temperature output, the Dwyer RHP-2O1D is an outside air (OSA)-mount unit measuring humidity to ±2% (10 to 90% RH @ 25°C). This Series RHP model, RHP-2O1D, senses humidity with a capacitance polymer element.
- RHP-2O1D: Supply for the 4-20 mA version: 10-35 VDC (loop powered)
- Pt100 RTD temperature sensor: DIN Class B, ±0.3°C @ 0°C (±0.54°F @ 32°F) on the RHP-2O1D
- Measures 0 to 100% RH; drift below 1% RH per year, hysteresis ±1%, response time 15 s (RHP-2O1D)
- RHP-2O1D: OSA housing: polycarbonate, NEMA 4X (IP66), 1/2" (22.3 mm) conduit connection, 1 lb (0.45 kg)
- Operating range -40 to 140°F (-40 to 60°C) on the RHP-2O1D
