Based on the visual details, this device is a Outdoor Air Temperature Sensor, most likely the T775-SENS-OAT or C7041F2006 model. These sensors are designed to provide accurate outdoor temperature readings for HVAC systems and building automation controllers.
Key Specifications
- Sensor Type: Depending on the exact model, it typically uses either a 1097 Ohm PTC (for T775 series) or a 20K Ohm NTC thermistor.
- Application: Used for sensing outdoor air temperature to optimize heating and cooling system performance.
- Design: Features a weatherproof enclosure with a 1/2-inch conduit connection for outdoor mounting.
- Operating Range: Typically rated for temperatures between -40°F and 158°F (-40°C to 70°C). [1, 2, 3]
Potential Model Variations
While they look nearly identical, the internal resistance differs:
- T775-SENS-OAT: 1097 Ohm PTC sensor used specifically with the T775 Series 2000 standalone controllers.
- C7041F2006: 20K Ohm NTC sensor used with Excel 10, 50, 80, 100, and 500 controllers.
