The safety instructions in this instructions manual are labelled as follows: If you do not observe these safety instructions, risk of an accident exists or the level sensor THE COOL ONE could be damaged. Useful information that will guarantee proper function of the sensor or facilitate your work.
Structure and mode of operation The level sensor THE COOL ONE consists of an encapsulated PTC thermistor and a probe tube, the height of which can be adjusted using a clampable screw-in body, or which is permanently installed using a fixed screw-in piece. The electrical connection of the level sensor is made via the integrated connection plug M12.

The level sensor THE COOL ONE is available in three different versions (types 1–3) (see Fig. 1). Types 1 and 2 have a clampable screw-in body (thread 3/4), with which the individual response length for each container can be adjusted by moving the probe tube in the screw-in body. These two types are highly suitable for installation above the liquid level.
Each probe length (Z) is permanently impressed at the top end of the probe. The probe length is provided as a distance dimension between this mark and the response point of the level sensor. (see Fig. 2) THE COOL ONE...
