Description

The Dwyer Instruments RHPX-3SBA0-00 transmitter utilizes a high-stability capacitive polymer sensing element to deliver precise measurements of relative humidity (0-100% RH) and ambient temperature. The integrated solid-state temperature sensor provides complementary thermal data for comprehensive environmental monitoring. The unit’s signal conditioning circuitry ensures a clean, linear analog output signal proportional to the measured parameters.

Housed in a compact, IP66-rated enclosure with a protective bronze filter, the transmitter is built for durability in demanding commercial and industrial settings. Its UL 2043 compliance allows for safe installation in air-handling spaces (plenums). The design prioritizes long-term stability and minimal drift, making it suitable for critical applications in energy management and facility automation where reliable data is essential.

Key Features

  • High-accuracy capacitive polymer humidity sensor with excellent long-term stability
  • Integrated solid-state temperature sensor with band-gap reference for precise thermal measurement
  • Versatile field-configurable analog output supports 4-20mA two-wire, 0-5V, or 0-10V voltage signals
  • Robust IP66 enclosure provides protection against dust and powerful water jets
  • Bronze particulate filter protects sensor element while allowing accurate air sampling
  • UL 94 V-0 flame-retardant and UL 2043 plenum-rated for safe use in air-handling spaces
  • Low power consumption (5 mA max) for energy-efficient operation from a 10-35 VDC supply
  • Removable terminal block simplifies wiring and maintenance procedures

Applications

  • HVAC system monitoring and control for energy efficiency in commercial buildings
  • Building Management Systems (BMS) and facility automation for museums, data centers, and clean rooms
  • Indoor air quality (IAQ) monitoring and demand-controlled ventilation
  • Environmental monitoring in warehouses, manufacturing facilities, and laboratories
  • Plenum space monitoring in accordance with UL 2043 safety standards

Frequently Asked Questions

What are the available analog output options for the Dwyer Instruments RHPX-3SBA0-00?

The transmitter features field-selectable analog outputs. You can configure it on-site to provide either a 4-20 mA two-wire current loop signal, a 0-5 VDC voltage output, or a 0-10 VDC voltage output. This flexibility allows for direct compatibility with most PLCs, DDCs, and building automation system controllers without requiring additional signal converters.

What is the power supply requirement for this humidity transmitter?

The unit operates from a 10 to 35 VDC power source. It has a low maximum current consumption of 5 mA, making it suitable for use with standard 24 VAC/VDC HVAC power supplies commonly found in building control panels. Ensure your power supply is within this voltage range and can provide the necessary current.

Can this sensor be installed in an air plenum space?

Yes, the Dwyer Instruments RHPX-3SBA0-00 is compliant with UL 2043, which is the standard for safety of heat and smoke release from installed electrical equipment in air-handling spaces. Combined with its UL 94 V-0 flame-retardant enclosure, it is approved for plenum installation where building codes require such ratings.

How is the sensor protected in dusty or harsh environments?

The transmitter is housed in an IP66-rated enclosure, which provides complete protection against dust ingress and powerful jets of water. Additionally, it is equipped with a bronze filter that prevents particulate matter from contaminating the sensitive capacitive polymer sensor element, ensuring long-term accuracy and reliability in challenging indoor conditions.
