TF25

Cable sensor for temperature measurement in HVAC applications. In conjunction with a Thermowell pocket suitable for temperature measurement in duct applications. Designed for control and monitoring applications. Replaces TF25 in enclosure USE-S (active/passive) resp. in the newly developed enclosure USE-M (LCD/relay/RS485 Modbus; LON: enclosure PA6, pure white, with quick lock screws).
