Measuring 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 …
Long-term stability vs. long-term drift
Christian Wirl | Know-howA value for long-term stability or long-term drift is usually given in the data sheets for pressure sensors. However, very few users are familiar with the exact meaning and, above all, the distinction between the two terms. Which standards are the two terms defined …
