Is it possible to connect a non-incendive Ex nA digital indicator to an intrinsically safe Ex i sensor in hazardous areas? Very often, signals from pressure sensors that do not have a built-in digital indicator for the measured value are connected to external digital …
In my last article I introduced you to how the “basic” proof of intrinsic safety can be provided for instruments and pressure sensors approved to ATEX in Europe. Each installer or operator must ensure that the employees in the plant are not endangered and …
In many pressure sensor applications, short-duration, high, impact loading occurs - this is referred to as shock. Shock resistance defines up to what level of acceleration the instrument can withstand the shock loading without being damaged in any way. The loading …
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 …
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 …
