Series BTT Temperature Transmitter

Description: The Series BTT Temperature Transmitter offers versatile temperature monitoring solutions for various applications, including HVAC air ducts, water lines in chillers, and outdoor air temperature measurement in both new and existing facilities. With mounting configurations for duct, immersion, and outside air installations, this transmitter provides flexibility to suit different environments. Duct and immersion models support probe lengths ranging from 2.5˝ to 18˝. Additionally, outside air models can be equipped with an optional radiation shield for direct sunlight exposure. Featuring a Pt1000 RTD temperature sensor, the BTT transmitter ensures accurate and reliable temperature measurements. Its robust construction with 304 SS probe and polycarbonate housing ensures durability in different operating conditions.
