Description

The Dwyer Instruments RHPX-3SWA0-00 Humidity and Temperature Transmitter employs advanced sensing elements to deliver stable, long-term monitoring of environmental conditions. Its design prioritizes signal integrity and durability, making it suitable for integration into building automation systems (BAS), energy management platforms, and precision climate control networks.

Engineered for low maintenance and high reliability, the transmitter operates from a 10-35 VDC supply, providing a conditioned analog signal proportional to the measured parameters. The IP66 enclosure ensures consistent performance in spaces subject to occasional moisture or dust, such as data centers, museums, cleanrooms, and commercial HVAC ducts.

Key Features

Dual-Function Monitoring: Combines a precision humidity sensor and a wide-range temperature sensor in a single, compact unit.
Selectable Output Signal: Configurable for 0-10V, 0-5V, or 4-20mA analog output to match existing control system inputs.
Industrial-Grade Durability: IP66-rated enclosure constructed from high-impact material for protection against harsh environmental factors.
Wide Operating Range: Functions accurately across an extensive temperature span from -40°C to 60°C.
Stable Long-Term Performance: Engineered sensing components minimize drift, reducing recalibration frequency and maintenance costs.
Simplified Wiring & Mounting: Features a removable screw terminal block and an attached lid for secure, tool-free electrical connections.

Applications

HVAC System Control: Precise humidity and temperature feedback for air handling units (AHUs), VAV boxes, and rooftop units to optimize comfort and energy efficiency.
Building Management Systems (BMS): Environmental monitoring in data centers, server rooms, museums, and archives where stable conditions are critical.
Industrial Process Monitoring: Climate control in manufacturing cleanrooms, pharmaceutical storage areas, and food processing facilities.
Indoor Air Quality (IAQ) Management: Integration into demand-controlled ventilation (DCV) systems in schools, offices, and commercial buildings.

Frequently Asked Questions

What is the power supply requirement for the Dwyer Instruments RHPX-3SWA0-00 transmitter?

The transmitter requires a 10-35 VDC power supply. It is designed for low power consumption and stable operation within this wide voltage range, making it compatible with standard 24 VDC building control systems and industrial power sources.

What analog output signals are selectable, and how are they configured?

The transmitter offers selectable analog outputs of 0-10V, 0-5V, or 4-20mA. Configuration is typically performed via internal DIP switches or jumpers accessible upon opening the enclosure, allowing you to match the signal type to your PLC, DDC, or data logger input requirements.

Is this sensor suitable for outdoor or damp indoor environments?

Yes, with its IP66-rated enclosure, the transmitter is protected against powerful water jets and dust ingress. This makes it suitable for damp indoor locations like greenhouses, basements, or outdoor applications under eaves, though direct, prolonged exposure to rain or submersion should be avoided.

How is the transmitter mounted and wired?

The unit is designed for wall mounting using integrated mounting holes. Wiring is simplified via a removable screw terminal block for secure power, output, and ground connections, with internal cable management to ensure a clean and reliable installation.
