Dwyer RHPX-2SDAB-00 2% Humidity/Temperature Transmitter Duct Mount Selectable Output (Type 2)

Product Description

Dwyer RHPX-2SDAB-00 is a duct-mount humidity and temperature transmitter with 2% RH accuracy, designed to provide selectable analog outputs for building and HVAC control systems. It uses a capacitance polymer humidity sensor and a 10K Type II thermistor, offers field-selectable 4-20 mA or 0-5/0-10 V outputs, and supports absolute or relative humidity, dew point, or enthalpy outputs. The unit includes an IP66 enclosure and removable terminal block.

• 2% RH accuracy with capacitance polymer humidity sensor and 10K Type II thermistor for temperature
• Selectable analog outputs: 4-20 mA or 0-5 VDC or 0-10 VDC (field selectable); input power ranges per model
• Duct-mount design with plenum probe option, IP66/NEMA 4X enclosure, removable terminal block, and optional two-line LCD

Product Highlights

2% RH accuracy; field-selectable 4-20 mA/0-5 V/0-10 V outputs; duct-mount IP66 enclosure with plenum probe option
