Series TE-OND/TE-RND/TE-OSA Outdoor Temperature Sensor

Brand: Dwyer Instruments, LLC

The Series TE-OND / TE-RND / TE-OSA Outdoor Air Temperature Sensors are offered in two different configurations to increase measurement accuracy by reducing radiated heat effects.

For applications where the north side of the building is accessible, the TE-OND/TE-OSA can be used to protect against low levels of radiated heat. If the sensor must be mounted in direct sunlight or a more precise measurement is required, our six plate radiation shield mounts over the temperature probe. 

The TE-RND radiation shield models can be surface or pipe mounted. All models include removeable terminal blocks to simplify wiring.
  • Weatherproof for outdoor installation
  • Radiation shield available to eliminate heating effects following installation in direct sunlight
  • Terminal connector eliminates need for wire nuts
