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 …

How does a pressure sensor behave in the overload area, that means outside the measuring range?
Anna Gries | PressureI 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 …
What is the functional principle of a resistive pressure transmitter?
Anna Gries | PressureThe functional principle of a resistive pressure transmitter is very simple. The pressure sensor converts the mechanical pressure value into a proportional electrical signal. The pressure sensor typically consists of a stable main body and a (thin) diaphragm. The …
How to measure the level of a liquid in a tank or how does the hydrostatic level measurement work?
Anna Gries | LevelThe level of a liquid such as water or oil in a tank or vessel can be measured indirectly by means of the hydrostatic pressure of the so-called “liquid column”. The hydrostatic pressure under a static liquid column increases directly with the height of the liquid …
