Frequently Asked Questions

What are the available output signals from this transmitter?

The Dwyer Instruments RHPX transmitter provides user-selectable analog outputs. You can configure it to deliver a 4-20 mA current loop signal, a 0-5 VDC voltage signal, or a 0-10 VDC voltage signal. This flexibility allows for direct compatibility with most PLC analog input modules, building management system controllers, and data acquisition systems.

What is the power supply requirement for this unit?

The transmitter operates on a wide-range DC power supply from 10 to 35 volts. This range accommodates common 12 VDC, 24 VDC, or other standard industrial power sources, simplifying integration into existing control panels and reducing the need for specific power conditioning equipment.

Is this sensor suitable for installation inside an air handling unit (AHU) or duct?

Yes, it is specifically designed for duct mounting. Its compact, IP66-rated enclosure and UL 2043 plenum rating make it ideal for installation directly in air ducts, air handling units, and other plenum spaces. The design includes a hydrophobic filter to protect the sensor from dust and moisture typical in these environments.

Does the transmitter require calibration?

The sensor is factory calibrated for high accuracy (±2% RH). While it offers excellent long-term stability, periodic field verification against a reference standard is recommended for critical applications to maintain optimal accuracy over extended periods, especially in harsh operating conditions.
