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.

The capacitive level sensor BEDIA NR 150 is suitable for liquids with low relative dielectric constant εr 1,8 … 6 (ref. εr 2,1). It has a MIN/MAX selector switch and the functions for MIN or MAX monitoring as well as other properties (output signal LSS or HSS, response delay etc.) are factory pre-set. The switch point is adjustable by means of a teach-in momentary switch.

The capacitive level sensor NR 160 is designed to monitor liquids and powders with high relative dielectric constant εr 35 … 85. The functions for MIN or MAX monitoring as well as other properties (output signal LSS or HSS, response delay etc.) are factory pre-set. The switch point is adjustable by means of a teach-in momentary switch.

The NR 260 is a capacitive level sensor for monitoring liquids. It is designed for use in fuel cells. The material is also suited to applications in the chemical industry for monitoring aggressive media. The functions for MIN or MAX monitoring as well as other properties (output signal LSS or HSS, response delay etc.) are factory pre-set. The Main Features of the NR 260 are high medium resistance of materials enamel, Hastelloy C4 2.4610 and stainless steel 1.4571 high protection class IP67 with connector short-circuit proof switching output 1 A, high side or low side switch MAX sensor or MIN sensor switch point factory pre-set for the following media: de-ionised water (conductivity < 4,2 μS/cm): 28 mm ± 2 mm tap water (conductivity ≈ 300 μS/cm): 22 mm ± 2 mm other media upon request; switch point adjustment via programmable interface on request
