How are absolute and relative pressure measuring ranges distinguished? There are considerable international differences. They can be explained in the following example: Europe: 0 … 10 bar / 0 … 10 bar abs America: 0 … 150 psig / 150 psia In Europe only the …

Pressure equipment directive 97/23/EC PED – Pressure limits 0.5 bar and 200 bar for pressure sensors and pressure transmitters
| Dominik Lorenz | PressureIn connection with the pressure equipment directive 97/23/EC (PED), a pressure limit of 200 bar is often mentioned. But what does this limit mean for manufacturers and/or companies that place pressure sensors, pressure transmitters and pressure equipment on the market? …
Autofrettage in pressure sensors ensures zero-point stability
| Eugen Gaßmann | PressureIn 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 …
