The term “dissipation loss” can be found in the data sheet for a pressure sensor or pressure transmitter. One needs this specification in order to be able to protect the pressure sensor from overheating. If a pressure sensor is operated in a hot environment, it …

Connection of an Ex nA digital indicator to an Ex i sensor
| Stefan Heusel | Know-howIs it possible to connect a non-incendive Ex nA digital indicator to an intrinsically safe Ex i sensor in hazardous areas? Very often, signals from pressure sensors that do not have a built-in digital indicator for the measured value are connected to external digital …
Shock resistance of pressure sensors
| Matthias Stratmann | Know-howIn many pressure sensor applications, short-duration, high, impact loading occurs - this is referred to as shock. Shock resistance defines up to what level of acceleration the instrument can withstand the shock loading without being damaged in any way. The loading …
Which vibrations are pressure transmitters subjected to in the laboratory?
| Matthias Stratmann | Know-howBasically, there are three common vibration tests with which the leading manufacturers test their instruments; with fixed and sweeping frequency (IEC 60068-2-6) and a broadband random pattern (IEC 60068-6-64). In the first test, the pressure transmitter is subjected to …
Vibration resistance of pressure sensors
| Matthias Stratmann | Know-howMeasuring instruments resp. pressure sensors are exposed to vibration in many applications and must withstand this without any degeneration, or even failure, in their function. Manufacturers of pressure sensors (also called pressure transmitters) therefore put a great …
