Dwyer RHPLC-2N1F Wall Mount Temp/Humidity Sensor | DLK

Maintaining thermal comfort according to ASHRAE 55 standards requires not only appropriate temperatures but also strict control of relative humidity. Excessively high humidity causes mold and reduces sweat evaporation, while low humidity causes dry skin and electronic static. For the central controller (DDC/BMS) to calculate air enthalpy and appropriately adjust cooling valves, the Dwyer RHPLC-2N1F wall-mount sensor is an indispensable signal transmission tool.

What is the Dwyer RHPLC-2N1F Sensor?

The RHPLC-2N1F model belongs to Dwyer Instruments' line of wall-mount air temperature and humidity transmitters. The device utilizes advanced Polymer capacitance sensors, allowing for highly sensitive measurement of water vapor changes in the air. The "2N1F" designation indicates a premium configuration with humidity measurement accuracy reaching ±2% (superior to the standard ±3%), providing reliable dual data back to the monitoring center.

Technical Features and Key Advantages

• Independent Signal Outputs: Allows the output of two separate Analog signals (one for temperature, one for humidity), ensuring DDC controllers receive parameters without overlap.

• Louvered Aerodynamic Enclosure Design: The ABS plastic housing features a directional louvered structure. Room air easily circulates through these openings to directly contact the internal probe, eliminating thermal error caused by circuit board heat dissipation (Self-heating).

• Ultra-Low Long-Term Drift: Premium polymer sensors maintain stability over many years of operation, minimizing the frequency of required recalibration in building projects.

Wall-Mount Sensor Placement Affects BMS Intelligence

A BMS system is only as smart as its Analog Input signals, which must accurately reflect reality. No matter how good a sensor is, if it's installed in the wrong location, it will provide "garbage" data to the PID control algorithm.

Crucial Principle: The RHPLC-2N1F must be installed at a height of approximately 1.5 meters from the floor. This area is known as the Breathing zone, accurately reflecting human perception. Never install the device on a Sun-loaded wall, right next to tempered glass windows, or directly facing a Supply diffuser. If 14°C cold air from an AHU blows straight onto the sensor, it will mistakenly assume the room has reached the setpoint and send a signal to close the water valve, while in reality, 90% of the room's remaining area is still hot.
