Dwyer Instruments RHPX-2SDAB-00 Duct Mount Humidity and Temperature Transmitter 2% RH Accuracy

The Dwyer Instruments Series RHPX-2SDAB-00 is a duct-mount relative humidity and temperature transmitter engineered to accurately monitor environmental conditions in commercial HVAC and building automation applications. Featuring a capacitance polymer humidity sensor with ±2% RH accuracy, this transmitter delivers reliable, long-term stability for demanding building control environments.

The RHPX-2SDAB-00 is configured with a small enclosure, plenum-rated plastic probe, and hydrophobic filter for use in supply and return air duct installations. Its selectable analog output makes integration with existing building management systems straightforward and flexible.

Key Features:

• ±2% relative humidity (RH) accuracy with capacitance polymer sensor
• Duct-mount configuration with plenum-rated plastic probe
• Hydrophobic filter for protection against condensation and moisture intrusion
• Selectable analog output (0-5 Vdc, 0-10 Vdc, or 4-20 mA)
• Small enclosure design for compact duct installations
• Optionally configurable for absolute humidity, dew point, or enthalpy output
• Removable terminal block for easy field wiring
• UL 2043 listed for plenum space installation
• No routine maintenance required after installation

The Series RHPX is an excellent choice for building energy management systems, commercial HVAC systems, clean rooms, museums, and data centers. Power supply options include 4-20 mA models at 10–35 Vdc and voltage output models at 15–35 Vdc or 15–29 Vac.
