Overview
The TF25+ measures temperature in HVAC and refrigeration applications. Fitted in a thermowell, it can also measure liquids. It connects over RS485 Modbus RTU and also has a 0 to 10 V or 0 to 5 V analogue output. The USE-M enclosure has a quick release cover and removable cable entries, and an optional colour LCD with traffic light function can show the value. Setup is by USEapp, uConfig, jumper or DIP switches. These two versions have a 1 m cable and a Ø6 mm stainless steel probe of 50 mm or 100 mm.
