Description

The Dwyer Instruments RHPX-2SWA0-00 transmitter employs a stable capacitive polymer sensor for humidity and a solid-state sensor for temperature, ensuring reliable long-term performance in environmental monitoring applications. Its design prioritizes signal integrity and resistance to environmental factors.

Housed in a compact, IP66-rated enclosure, this unit is built for durability in both indoor and protected outdoor installations. The selectable active analog output simplifies interfacing with a wide range of building management systems, data loggers, and PLCs, providing a conditioned signal ready for direct use.

Key Features

High-Accuracy Sensing: Capacitive polymer humidity sensor delivers ±2% RH accuracy across a 10–90% range at 25°C.
Wide Operating Range: Monitors full-scale humidity (0-100% RH) and a broad temperature span from -40°C to 60°C.
Configurable Analog Output: Features active, selectable 0-5V or 0-10V voltage output signals for flexible system integration.
Robust Environmental Protection: IP66 rating safeguards the electronics against dust ingress and powerful water jets.
Simplified Installation: Compact wall-mount design with a removable terminal block enables tool-free wiring and easy maintenance.
Low Power Operation: Consumes a maximum of 5 mA, compatible with standard 10–35 VDC power supplies common in industrial settings.
Long-Term Stability: Engineered sensor technology ensures minimal drift and reliable performance over extended periods.

Frequently Asked Questions

What is the output signal of the RHPX-2SWA0-00 transmitter?

The transmitter provides an active, selectable analog voltage output. You can configure it to deliver either a 0-5V or a 0-10V signal corresponding to the 0-100% RH measurement range. This makes it directly compatible with most PLC analog input modules and building automation controllers.

What power supply does this humidity transmitter require?

It operates on a 10 to 35 VDC power supply. The device has low power consumption, with a maximum operating current of 5 mA. Ensure your power source is within this voltage range and can provide the necessary current for stable operation.

Is the Dwyer Instruments RHPX-2SWA0-00 suitable for outdoor use?

Yes, its IP66-rated enclosure provides a high degree of protection against dust ingress and powerful water jets from any direction. This makes it suitable for outdoor installation in sheltered locations or in demanding indoor environments like wash-down areas.

How accurate is the temperature measurement on this unit?

The integrated temperature sensor has a typical accuracy of ±0.5°C at 25°C. It provides reliable readings across its full operating range of -40°C to 60°C, which is essential for precise environmental control and compensation in humidity calculations.
