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. Wall mount models are available on the Series BTT-E/N page.
NIST CALIBRATION available in Product Configurator.
