A 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 …
Within 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 …
The question about the difference between an absolute pressure and a gauge (relative) pressure measurement always pops up every now and again. From a purely theoretical point of view, the question can be answered relatively easily: in a gauge pressure measurement …
Particularly 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 …
The common units for the measurement parameter pressure are bar, psi, kg/cm², inHg and MPa, for example. In most cases, one unit has become established in a particular country or region. As a result, it often happens that one must convert a given pressure value into …
