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, ceramic thick-film and piezo-resistive sensors. …
In the machine-building industry, it has become common practice to use electronic pressure switches. The use of mechanical pressure switches is on the decline. The advantages of the electronic version of the pressure switch are a digital display, adjustable switch …
What exactly is the difference between the 4-20 mA output signal in 2- and 3-wire technology? This question is answered best from the viewpoint of the user: An output signal in 2-wire technology means: less wiring required better EMC protection, since interferences …
In the manufacturing operation of pressure sensors, autofrettage denotes the process of active "overload" by subjecting the pressure sensor selectively once or several times to a pressure above the nominal pressure range . This process is applied, in order to achieve …
I have often been asked about the behaviour of a pressure sensor outside the specified measuring range, that means in the overload area and what will happen if the overload limit of a pressure sensor is exceeded. This fact is described as follows in the book …
