Pressure 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 …
Ex barrier and intrinsically safe pressure sensors – an inseparable pair
Stefan Heusel | Know-howWithin the European Community, intrinsically safe pressure sensors may only be used in hazardous areas if they are installed in conjunction with an Ex barrier. The combination of pressure sensor and Ex barrier must meet the “ Proof of intrinsic safety ” in …
Defeat pressure spikes – prevent damage to pressure measuring instruments
Stefan Heusel | Know-howParticularly when measuring the pressure of fluids in piping systems, pressure sensors are consistently destroyed by overpressure. The analysis of the damaged equipment often then shows that a significantly higher pressure than the prevailing system pressure in the …
Dust explosion, the underestimated danger – Pressure sensors must meet requirements for the maximum permissible surface temperature
Stefan Heusel | Know-howWith the key phrase “potentially explosive atmospheres”, many users immediately think about areas that contain flammable gases and now know that only ATEX-approved pressure sensors may be used in plant and machinery in these areas. Frequently, however, they …
