Description

The Dwyer Instruments RHPX-2SDA0-00 transmitter utilizes a stable capacitive humidity sensor paired with an integrated temperature sensor to deliver precise environmental data for HVAC control and energy management. Its loop-powered design (10-35 VDC) simplifies installation while providing reliable, long-term performance with minimal drift.

Engineered for commercial and industrial ductwork, the transmitter features a compact, tool-free mounting design. The hydrophobic filter protects the sensing element from condensation and contaminants, ensuring accuracy in variable air handling conditions. Compliance with UL 2043 makes it suitable for installation in air-handling plenums.

Key Features

  • High-accuracy capacitive humidity sensing with ±2% RH specification.
  • Integrated temperature measurement across a -40°C to +60°C range.
  • Configurable analog output signals: 4-20mA (2-wire), 0-5V, or 0-10V.
  • Durable, IP66-rated plastic enclosure resistant to dust and water jets.
  • Plenum-rated probe construction with hydrophobic filter for sensor longevity.
  • Loop-powered operation (10-35 VDC) reduces wiring complexity.
  • UL 94 V-0 flammability rating and UL 2043 plenum space compliance.
  • Compact, duct-mount form factor for easy integration into existing HVAC systems.

Applications

  • Precise humidity and temperature monitoring in commercial HVAC ductwork.
  • Building automation and energy management systems (BMS/BAS).
  • Environmental control in data centers, laboratories, and cleanrooms.
  • Industrial process monitoring where stable ambient conditions are critical.
  • Ventilation control in schools, offices, and healthcare facilities.

Frequently Asked Questions

What are the available output signals from this Dwyer Instruments transmitter?

The RHPX-2SDA0-00 offers three selectable analog output configurations: a 2-wire 4-20mA current loop, a 0-5V voltage output, or a 0-10V voltage output. This flexibility allows direct integration with most PLC analog input modules, DDC controllers, and building management system data loggers without requiring additional signal conditioning.

What is the power supply requirement for this humidity transmitter?

This is a loop-powered transmitter requiring a DC supply voltage between 10 and 35 VDC. The device draws power from the same two wires used for the 4-20mA signal output. For voltage output modes (0-5V or 0-10V), a separate power connection within the same voltage range is required.

Is this sensor suitable for installation in air-handling plenum spaces?

Yes. The transmitter's probe is constructed with plenum-rated plastic materials and the unit complies with UL 2043 for installation in air-handling plenums. This certification ensures it meets specific fire safety and smoke emission standards required for spaces used for environmental air distribution.

How is the sensor protected in high-humidity duct environments?

The probe is equipped with a hydrophobic (water-repellent) filter. This filter protects the internal capacitive sensing element from condensation, dust, and other airborne contaminants, ensuring long-term measurement accuracy and stability even in variable humidity conditions typical of HVAC systems.
