Dwyer Instruments RHP-2D1A Sensor
The Dwyer Instruments RHP-2D1A is a high-performance duct mount humidity and temperature transmitter engineered for precision environmental monitoring in commercial and industrial HVACR systems. This dual-purpose sensor utilizes a capacitance polymer humidity sensor, ensuring rapid recovery from 100% saturation while maintaining a 2% RH accuracy rating within the 10% to 90% range. For temperature sensing, the unit is equipped with a passive 10K Type III thermistor (Curve A), providing reliable thermal feedback without the need for additional power for the temperature loop, which simplifies total system HVAC sensor wiring.
Designed for longevity in demanding environments, the RHP-2D1A features a robust PBT enclosure and a 1/2" NPS conduit connection for secure installation. The 4-20 mA humidity output is loop-powered (10-35 VDC), offering superior noise immunity over long cable runs compared to voltage-based signals. This model is ideal for building automation systems (BAS), clean rooms, and air economizer applications where NEMA 4X protection for the housing is required to prevent sensor degradation from contaminants or high-moisture conditions.
Key Benefits for Technicians
- High Accuracy Monitoring: Delivers ±2% RH precision and ±0.36°F temperature accuracy for critical climate control.
- Contamination Resistance: The advanced polymer sensor is designed to resist drift caused by fog, high humidity, or common airborne pollutants.
- Field Serviceability: Features a removable hydrophobic filter and a replaceable sensor design to reduce downtime and inventory costs.
- Versatile Integration: The 4-20 mA current loop for humidity allows for long-distance signal transmission with minimal interference.
Common Questions & Technical Support
Does the RHP-2D1A require separate power for the temperature sensor?
No, this model uses a passive 10K Ohm @ 25°C Type III thermistor. Only the humidity transmitter portion requires loop power (10-35 VDC) to function.
Can I use this sensor in high-velocity supply air ducts?
Yes, though for extreme conditions or high-velocity areas, it is recommended to ensure the sensor probe is positioned correctly to avoid excessive vibration or to use a sintered filter if specified for the job site.
What is the maximum operating range for this transmitter?
The sensor is rated for operation between -40°F and 140°F (-40°C to 60°C), making it suitable for a wide range of standard HVAC duct environments.
