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 intrinsic safety? relative to the 94/9/EC ATEX directive. เกจวัดแรงดัน of sensor and barrier from different manufacturers fulfil this problem.
On the main one hand, it might be that the safety or Ex characteristic values do not match, alternatively, the functional characteristics must also match the application. So, even if the safety-related data match, the couple of Ex barrier and pressure sensor may not match since, for example, both components work ?passively?.
(Additional information about them ?active?/?passive? can be found in your blog article ?Electrical circuitry for pressure sensors: when is really a sensor active, and when passive??)
Therefore, you should make sure that you only use barriers and sensors together whose safety-related data and function-related data match one another. We therefore directly recommend, in our intrinsically safe pressure sensors? data sheets, a potentially compatible intrinsically safe Ex barrier.
