Dwyer RHP-3D1D | Duct Humidity/Temperature Transmitter | ±3% RH, 4-20 mA RH, 100 Ω RTD
With a 4-20 mA humidity output plus a passive 100 Ω RTD (DIN 385) temperature output, the Dwyer RHP-3D1D is a duct-mount unit measuring humidity to ±3% (20 to 80% RH @ 25°C). A capacitance polymer sensor handles humidity measurement in the Series RHP RHP-3D1D.
- Supply for the 4-20 mA version: 10-35 VDC (loop powered) on the RHP-3D1D
- 100 Ω RTD temperature sensor: DIN Class B, ±0.3°C @ 0°C (±0.54°F @ 32°F) (RHP-3D1D)
- RHP-3D1D: Measures 0 to 100% RH; drift below 1% RH per year, hysteresis ±1%, response time 15 s
- Duct mount: NEMA 4X (IP66) housing, 1/2" NPS conduit connection, 0.616 lb (0.3 kg) on the RHP-3D1D
- Operating range -40 to 140°F (-40 to 60°C) (RHP-3D1D)
