Failure causes and sources of errors in sensors: Mechanical failure – defected cables, lines or connectors
Stefan Heusel | Know-howCable break / lead breakage, broken connectors and damaged cable insulation – many of these failure causes and sources of errors in sensors can be traced back to mechanical failure of qualitatively inferior components. You have carefully selected a supplier for …
Use of pressure sensors in medical oxygen applications – What should be considered?
Stefan Heusel | ApplicationsIn order to use pressure sensors/pressure transmitters in oxygen applications, the cleanliness of all parts in contact with the medium needs to fulfil certain standards. This is due to the fact that increased pressure or an increased oxygen content in the medium can …
SIL 2 and SIL 2 does not automatically equal SIL 2
Stefan Heusel | Know-howWhen using pressure sensors in safety-relevant applications, sooner or later one must ask the question whether the SIL evaluation of the proposed pressure sensor is sufficient for the application. Often, the user tends to favour pressure sensors with higher SIL …
Analogue output signals from pressure sensors 3: 0.5 … 4.5 V ratiometric
Stefan Heusel | Know-howFor some applications, for example in vehicles or battery operated applications, an output signal is required which can be operated at low power to enable a long service life. Normally, ratiometric signals are transmitted as 10 ... 90 % of the powersupply voltage. …
