Supported Applications
The Model RP1 is a wired thermo-hygrometer probe designed for use with the Dwyer Model UHH. It measures humidity, temperature, dew point, and wet bulb temperatures in clean air service.
Operating Conditions & Performance
The series operates within specific environmental limits to ensure measurement integrity. The process temperature limit is -40 to 176°F (-40 to 100°C), while the ambient operating temperature range is 5 to 125°F (-15 to 51°C). Measurement ranges cover relative humidity from 0 to 100% (non-condensing) and temperatures from -20 to 140°F (-29 to 60°C).
Accuracy specifications are defined as follows:
- RH: ±2% @ 25°C (10 to 90% RH); ±4% (0 to 10, 90 to 100% RH)
- Temperature: ±0.54 @ 77°F (±0.3 @ 25°C)
The probe features a response time of 1.5 s.
Configuration Options
The Model RP1 is offered as an insertion-style sensor with the following documented physical and compliance characteristics:
- Insertion Length: 8" (203 mm)
- Weight: 12.8 oz (362 g)
- Service Media: Clean air
- Agency Approvals: CE, RoHS
The series identity is represented by the model number guide RP1 - <Model>. Specific electrical connection types, process connections, wetted materials, and housing configurations are not detailed in the provided documentation.
Key Product Differences
The Model RP1 is a single-configuration wired probe intended for integration with the Dwyer Model UHH controller. No alternative housings, output signal types, or sensor element variations are documented within this series bundle.
