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.

EGE capacitive level sensors for adhesive media offer the reliable monitoring of the filling level of granulate, powders, solids, such as feathers, fluids and aggressive as well as adhesive media. The medium to be detected functions as dielectric. The medium in touch with the sensor generates a capacity change. This is converted into a switching signal or an analogue 4...20 mA output signal. 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.

The modules of the IMSP series are connected before the interface devices and provide reliable protection against voltage surges. The only 6.2 mm wide DIN rail devices are IP20 rated and can be used in the Ex and non-Ex area. Among other things, modules are available for surge-protected connection of analog signals (e.g. for analog signal isolators and temperature measuring amplifiers) as well as for connecting binary signals from switches or inductive and capacitive sensors.

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.

The capaNCDT DTV series is designed for non-contact detection of Disc Thickness Variation (DTV). Capacitive sensors for multi-track measurements and a carrying case including the complete measurement channel for mobile use are available. With the capaNCDT DTV measurement system, capacitive displacement sensors determine the thickness of the brake discs from both sides based on the difference principle. While the brake disc rotates, the thickness deviation is determined via the circumference of the entire disc. Using several sensors in pairs or the CSH1,4FL multi-channel sensor makes multi-track thickness measurement possible. Thickness measurements can be carried out in test benches, in road tests or in car repair shops. The DTV case is intended for mobile use, e.g., for quality assurance purposes and warranty claims.

Application examples are often found where the standard versions of the sensors and the controller are performing at their limits.
