VFG54+ relay / LCD / BUS

Sensor for temperature measurement at the surface of pipes (cold or warm water) and round surfaces. Spring loaded brass contact sensor with direct contact for fast response. For tightening straps and contact fluid please see accessories. The devices with relay output for a 2-point controller or a 2-stage 2-point controller and color-changing LCD allow a wide range of applications. Depending on the model, the sensor can be individually configured via Thermokon USEapp. Tool-free opening, closing and wiring as well as removable cable entries ensure quick and easy installation.
