Dwyer RHPX-3SDA0-00 / RHPX-3SDA0-00-LCD Relative
Humidity/Temperature Transmitter
Product Introduction
The Dwyer RHPX-3SDA0-00 Series Relative Humidity/Temperature
Transmitter is a compact, versatile solution designed for precise
environmental monitoring in commercial and industrial settings.
Equipped with multiple on-board sensors, it simultaneously measures
humidity and temperature while reducing installation complexity.
The transmitter features a UV-rated outdoor enclosure for
durability in harsh conditions and meets UL 2043 compliance for
safe installation in plenum spaces. With a removable terminal
block, attached lid, and integrated cable management, it ensures
quick setup and minimal maintenance—ideal for HVAC systems,
building automation, and environmental control applications
Product Features
Dual-Sensor Integration:
On-board sensors for simultaneous relative humidity (RH) and
temperature measurement.
Eliminates the need for separate devices, reducing equipment and
installation costs.
Installation Efficiency:
Removable terminal block allows pre-wiring for faster setup.
Attached lid and cable management system organize wiring for neat,
code-compliant installations.
Environmental Durability:
UV-rated outdoor enclosure resists degradation from sunlight and
weather.
