SFKH02+ relay / LCD / BUS

Immersion sensor with neck pipe for temperature measurement of gases and liquids in pipework applications. With the 70 mm neck pipe it is designed for applications with insulation materials. The sensor can optionally be screwed directly into a bonded pocket (see accessories). The measuring insert can be exchanged without disassembling the entire sensor. 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.
