Dwyer RHP-3D20 | Duct Humidity Transmitter | ±3% RH, 0-10 VDC RH
Built for duct mounting, the Dwyer RHP-3D20 measures relative humidity to ±3% (20 to 80% RH @ 25°C) and provides a 0-10 VDC humidity output only. The RHP-3D20 belongs to Series RHP and uses a capacitance polymer humidity sensor.
- Supply for the 0-10 VDC version: 15-35 VDC or 15-29 VAC on the RHP-3D20
- Measures 0 to 100% RH; drift below 1% RH per year, hysteresis ±1%, response time 15 s (RHP-3D20)
- RHP-3D20: Duct mount: NEMA 4X (IP66) housing, 1/2" NPS conduit connection, 0.616 lb (0.3 kg)
- Operating range -40 to 140°F (-40 to 60°C) on the RHP-3D20
