RAIN SENSOR

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

Capacitive sensors are designed for non-contact measurement of displacement, distance and position, as well as for thickness measurement. Due to their high signal stability and resolution, capacitive displacement sensors are applied in laboratories and industrial measurement tasks. In production control, for example, capacitive sensors measure film thickness and application of the adhesive. Installed in machines, they monitor displacement and tool positions.
