Ex barrier and intrinsically safe burden sensors – an inseparable pair

Ex barrier and intrinsically safe burden sensors an inseparable pair

Within the European Community, intrinsically safe burden sensors may alone be acclimated in chancy areas if they are installed in affiliation with an Ex barrier. The aggregate of burden Catalytic Gas Sensor and Ex barrier accept to accommodated the “Proof of built-in safety” in accordance with the 94/9/EC ATEX directive. Not all combinations of sensor and barrier from altered manufacturers fulfil this condition.

On the one hand, it may be that electrochemical gas sensor the assurance or Ex appropriate ethics do not match, on the added hand, the anatomic characteristics must aswell bout your application. So, even if the safety-related abstracts match, the brace of Ex barrier and burden sensor ability not bout since, for example, both apparatus plan “passively”. (Additional advice on the accountable “active”/“passive” can be begin in the blog commodity “Electrical chip for burden sensors: if is a sensor active, and if passive?”) Therefore, you should accomplish abiding that you alone use barriers and sensors calm whose safety-related abstracts and function-related abstracts bout anniversary other.

We accordingly anon recommend, in our intrinsically safe burden sensors’ abstracts sheets, a potentially accordant intrinsically safe Ex barrier. If you accept any added wholesale industrial questions, our sales administration will acquiescently action you a abundant appliance consultation.
