 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. Wall mount models are available on the Series BTT-E/N page.

• 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
