Your expert for intrinsic safety

Stef­fen Scholle

I offer con­sult­ing, sem­i­nars and devel­op­ment sup­port in the field of elec­tri­cal explo­sion pro­tec­tion and accom­pa­ny you through the entire cer­ti­fi­ca­tion process. My focus is on the intrin­sic safe­ty type of pro­tec­tion (Ex i), sup­ple­ment­ed by exten­sive expe­ri­ence in oth­er elec­tri­cal types of pro­tec­tion.

Why “Ex i” is one of the most flexible and safest types of ignition protection

Understanding intrinsic safety — simple and practical

What is intrin­sic safe­ty?
Intrin­sic safe­ty — or “Ex i” — is one of the most impor­tant types of igni­tion pro­tec­tion for elec­tri­cal devices in poten­tial­ly explo­sive atmos­pheres. But what exact­ly is it? And why does it play such an impor­tant role in prac­tice?

The big advan­tage: with intrin­si­cal­ly safe cir­cuits, the ener­gy is lim­it­ed in such a way that no igni­tion source can arise even in the event of a fault. This makes this type of pro­tec­tion par­tic­u­lar­ly reli­able and flex­i­ble — for exam­ple for sen­sors, hand-held devices or small con­trol com­po­nents that are used in gas or dust atmos­pheres.

Devices with intrin­si­cal­ly safe pro­tec­tion lev­el ia ful­fil the high­est require­ments and may there­fore also be used in Zone 0 (gas) and Zone 20 (dust) — i.e. in areas in which an explo­sive atmos­phere is present per­ma­nent­ly or for long peri­ods of time. Intrin­sic safe­ty is also a glob­al­ly recog­nised and estab­lished type of pro­tec­tion and plays a cen­tral role in inter­na­tion­al approvals and the safe oper­a­tion of elec­tri­cal devices in haz­ardous areas.

Technical understanding meets approval expertise

As an elec­tri­cal engi­neer with roots in prod­uct devel­op­ment, I know the chal­lenges that devel­op­ers face in explo­sion pro­tec­tion — from my own expe­ri­ence.

Through my work in indus­try and at DEKRA as an inspec­tor, sem­i­nar leader and audi­tor, I have learnt not only to under­stand tech­ni­cal stan­dards, but also to apply and com­mu­ni­cate them in a prac­ti­cal way.

With Exi­Men­tor, I sup­port devel­op­ers, project man­agers and approval offi­cers in effi­cient­ly lead­ing Ex projects to type approval.

If you are look­ing for a com­pe­tent part­ner at eye lev­el — I look for­ward to hear­ing from you.

“Tak­ing explo­sion pro­tec­tion into account ear­ly on ensures reli­able project plan­ning.”

From the idea to approval

I specialise in providing technical support in explosion protection.

I sup­port you in all phas­es of your cer­ti­fi­ca­tion project — with prac­ti­cal train­ing, tar­get­ed advice and tech­ni­cal sup­port dur­ing the devel­op­ment and approval process. My range of ser­vices is aimed at any­one who wants to bring elec­tri­cal devices in explo­sion pro­tec­tion to type approval effi­cient­ly, in com­pli­ance with stan­dards and with tech­ni­cal­ly con­vinc­ing doc­u­men­ta­tion.
