The TLS 100 tube sensor works on the capacitive measuring principle and detects the presence of a liquid in a plastic tube. These plastic tubes may also be mounted as a by-pass on a compensator in order to signal the required medium level in containers. The sensor is simply snapped onto the tube at the ideal level of the medium and provides versatile usage for a wide range of applications in medical equipment, the food stuffs industry etc. The sensor can additionally be fixed by means of the two mounting lugs to ensure a tight fit on the tube. Caution The switch point is factory pre-set so as to lie exactly between the two mounting clips. When readjusting the switch point, please observe that it again lies between the two clips. A mass surface in the proximity (< 10 mm) may influence the switch point and may necessitate a readjustment.

Level sensors of series KGFR are ideal for media with low DK value. The PTFE sleeve makes the sensor resistant to aggressive media and together with the round design ensures the fast slippage of the medium.

Capacitive sensors work contactless, reactionless and wear-free. Thanks to their high sensitivity and the ability to detect electrically conductive as well as non-conductive objects, they can be used in many different applications. They even detect levels of liquids or solids. In addition to position measurement, further important application areas are overflow protection, dry run protection of pumps and leakage detection.

In its sensor housing, the combiSENSOR combines two displacement sensors. This unique sensor concept enables one-sided thickness measurement of electrically non-conductive materials on metallic objects. Its field of application is the thickness measurement of plastic film or of plastic coating on metal plates. The eddy current sensor penetrates the plastic layer and measures the distance to a metallic material underneath it, e.g. a metal plate. The capacitive sensor synchronously detects the distance to the plastic material. The thickness is determined based on the difference of both sensor signals.
