The DE46 is a multi-functional switching unit with an optional transmitter output. It is suitable for measuring overpressure, under-pressure and differential pressure in gaseous media. Typical applications are filter equipment, precision air channel measurements, clean room pressure equalisation, burner under-pressure measurement, furnace circulating air control. This switching device is based on a capacitive sensor element that is suitable for measuring overpressure, underpressure and differential pressure. The measured pressure acts on the sensor element with a micromechanically produced differential condenser in silicon-glass technology. Changes in pressure generate changes in capacity, which is evaluated by the device's electronics and transformed into signals on the display, switch contacts and an output signal.
