Description

The RHPX-2LHA0-00 transmitter utilizes a precision capacitive polymer humidity sensor paired with a solid-state band-gap temperature sensor to deliver stable and reliable environmental data. Its advanced signal conditioning ensures minimal drift and high repeatability for long-term monitoring applications in demanding conditions.

Designed for commercial and industrial installations, the large enclosure provides superior protection against dust and water jets (IP66). The integrated HDPE filter and solar shield mitigate measurement errors caused by particulate contamination and direct solar heating, ensuring data integrity in outdoor or challenging indoor environments like data centers and clean rooms.

Key Features

  • Precision Measurement: Delivers ±2% RH humidity accuracy and ±0.5°C temperature accuracy at 25°C.
  • Flexible Power & Output: Operates on 15-35 VDC/15-29 VAC and offers user-selectable 4-20mA, 0-5V, or 0-10V analog outputs.
  • Durable Construction: UV-rated, IP66 enclosure made from UL 94 V-0 flame-retardant material.
  • Advanced Environmental Shielding: Equipped with an HDPE filter and solar radiation shield for stable readings.
  • Engineered for Ease: Removable terminal block facilitates quick wiring and maintenance.
  • Compliant Design: Meets UL 2043 standards for installation in air-handling plenums.
  • Wide Operational Range: Functions reliably from -40°C to 60°C with a 0-100% RH sensing span.

Applications

  • HVAC and Building Management System (BMS) monitoring and control.
  • Environmental preservation in museums, archives, and clean rooms.
  • Data center and server room climate control and energy management.
  • Industrial process monitoring where stable humidity and temperature are critical.
  • Plenum space installation in commercial air handling systems.

Frequently Asked Questions

What are the available analog output options for this transmitter?

The transmitter is field-configurable to provide a single output signal. You can select between a 2-wire 4-20mA current loop, a 0-5V DC voltage output, or a 0-10V DC voltage output. The selection is made via internal jumpers or configuration on the removable terminal block, allowing integration with most PLCs, BMS controllers, and data loggers.

What is the power supply requirement for the Dwyer Instruments RHPX-2LHA0-00?

The unit requires a 15-35 VDC or 15-29 VAC power supply. For voltage output models (0-5V or 0-10V), the maximum operating current is 5 mA. Ensure your power source can provide stable voltage within this range for accurate sensor operation and signal output.

Is this sensor suitable for outdoor installation or harsh environments?

Yes, its IP66 rating makes it dust-tight and protected against powerful water jets, suitable for many outdoor and industrial environments. The UV-stable enclosure, HDPE filter, and integrated solar radiation shield further protect the sensing elements from weather, contamination, and solar heating effects, ensuring long-term reliability.

How is the transmitter mounted and wired?

It is designed for wall mounting using the integrated bracket on the large enclosure. Wiring is simplified via a removable screw terminal block, allowing for easy connection of power, output, and ground wires without specialized tools. The design facilitates quick replacement or maintenance.
