Basically, 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 …
What is meant by the “window” switching function with electronic pressure switches?
| Enrico Bossart | Know-howModern electronic switches often offer a variety of different adjustable switching functions, such as the so-called “window”. When one talks of the “window” switching function, it means the monitoring of a defined measuring range (for example, for the …
What is meant by the switching function “hysteresis” with electronic pressure switches?
| Enrico Bossart | Know-howThe hysteresis switching function is generally included for all switch variants, whether mechanical or electronic, and whether for the parameter of pressure, temperature, level or flow. Hysteresis is generally understood to be the difference between the switch point …
Vibration and shock loading on pressure transmitters
| Matthias Stratmann | Know-howPressure transmitters are subjected to vibration and mechanical shocks in many applications and also during transport. Below, the terms shock and vibration will be explained in greater detail. Particularly strong vibrations can act on pressure transmitters, for …
