Tube sensor TLS100
Description
The TLS100 tube sensor works on the capacitive measuring principleand 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 themedium 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 mountinglugs to ensure a tight fit on the tube.
