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 …
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 …
With 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 …
An important parameter in the use of pressure sensors in safety devices is the so-called “Diagnostic Coverage” (DC). However, since single-channel, in particular, but also two-channel safety circuits often malfunction or may be defective, a known diagnostic …
In the European Union, the ATEX Directive 94/9/CE is compulsory for plants or machines, in which hazardous substances are processed or produced. It states that only ATEX-approved instruments must be used in hazardous areas within Europe. One frequently selected …
