Frequently Asked Questions

What are the available analog output options for this transmitter?

The Dwyer Instruments RHPX-3SDA0-00 transmitter features a field-selectable analog output. You can configure it on-site to provide either a 4-20mA two-wire current loop signal, a 0-5V DC voltage output, or a 0-10V DC voltage output. This flexibility allows for direct compatibility with most PLC analog input modules, building management system controllers, and data loggers without requiring additional signal conditioners.

Is this sensor suitable for installation inside an air duct?

Yes, this transmitter is specifically designed for duct-mount installation. Its probe is 250mm long for insertion into the air stream, and the compact IP66-rated enclosure mounts externally on the duct wall. This design provides accurate measurement of the conditioned air while protecting the electronics. The unit is UL compliant and approved for use in plenum spaces commonly found in HVAC systems.

What is the operating temperature range and accuracy of the humidity sensor?

The transmitter operates across a wide ambient temperature range of -40°C to 60°C. The capacitive polymer humidity sensor provides a measurement accuracy of ±3% RH within the 10% to 90% RH band at 25°C. This performance makes it reliable for demanding environments, from cold air intake ducts to hot supply air plenums, ensuring stable readings over extended periods.
