The recovery of drinking water from ground water has top priority in many countries. In Germany, this method has a share of about 70 per cent in the water supply. The water drawn from depths of several hundred of meters below the earth’s surface is normally in …
Front flush diaphragm pressure connections are required whenever the pressure channel of a standard pressure sensor may become clogged or damaged in use. This problem is encountered, for example, with crystalline, viscous, aggressive, adhering or abrasive media. …
The submersible pressure transmitter, sometimes also referred to as a level probe, is a special type of pressure sensor used for level measurements in e.g. tanks, wells, shafts and bore holes. For level measurements, the level probe is submersed directly into the …
There is no “ideal” sensor principle. Of particularly great importance and widespread use are resistive sensor technologies, due to their reliability. For electronic pressure sensors, WIKA is using metal thin-film and piezo-resistive sensors. Each of the two …
