Outside Air Temperature Transmitter with 4 to 20 mA Output

Series BTT Temperature Transmitters

Current or Voltage Output; NEMA 4X Enclosures

The Series BTT Temperature Transmitters offer transmitter output signals with the same form and fit as our popular TE thermistor and RTD sensors for building HVAC applications. Thermowells are required when using immersion models in liquid applications.

NIST CALIBRATION available in Product Configurator.

The wall mount models can also be seen on the Series BTT-E/N page.

Product Applications

Building automation system temperature monitoring

Duct, immersion, and outside air models available
Radiation shield available for mounting in direct sunlight
Transmitter output allows for longer wire runs than standard thermistor sensors
