TF25+ BUS

Show items

Cable sensor for temperature measurement in HVAC or refrigeration applications. In combination with a thermowell, the TF25 can also be used for temperature measurement in liquid media. Depending on the application requirements, different PVC, silicone, PTFE and fibreglass cables are available. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation.
