Rechner Sensor

Product catalogue of capacitive sensors Rechner Sensors

Rechner SensorsĀ is a specialist in capacitive sensing technology for automation, level control, and quality control applications. The Rechner product line includes over 3,000 capacitive prox, inductive prox, magneto-resistive sensors, power supply logic controllers, flow sensors, and HazLoc barriers: all in different sizes and mounting options.

Capacitive sensors work by measuring the dielectric of the material around the sensor. This dielectric value increases both when there is more material in front of the sensor and the closer that the material gets to the sensor. This means that capacitive sensors work differently than inductive proximity sensors. Capacitive sensors can detect virtually any material whereas inductive sensors are designed to sense only ferric materials. Capacitive sensors are indifferent to color and work with both liquids and solids.

Since all materials have different dielectric properties, it is possible to adjust a capacitive sensor to detect the presence of a specific material under a variety of conditions. This makes capacitive sensors great at detecting the presence of objects (especially non-metal objects) and detecting the level of material in containers, tanks, and silos.

Rechner capacitive proximity sensors can detect and switch reliably with materials that have dielectric constants as low as 1.1 Er. Rechner capacitive sensors also work at high temperatures up to 250 degrees Celsius (482 degrees Fahrenheit).
