The enclosures of the manufacturer’s intrinsically safe voltage transformers and flameproof voltage transformers are the same; can such an intrinsically safe instrument be used as a flameproof instrument? Do we need to consider temperature groups? Can intrinsically safe instruments experience an increase in surface temperature due to the absence of intrinsically safe cables and safety barriers?
It doesn’t seem suitable for use as an explosion-proof solution; intrinsically safe systems involve electrical current limitation, while explosion-proof designs rely on the enclosure to prevent explosions – they are fundamentally different. Moreover, intrinsically safe instruments should be connected to an intrinsically safe circuit; it shouldn’t work without a safety barrier.
To achieve standardized production, instrument manufacturers have used the same enclosures for intrinsically safe instruments and flameproof instruments. I believe that in the event of an internal explosion, the energy will not escape outside, so such instruments can be used as flameproof ones
Intrinsic safety instruments can be used in various explosion-proof areas; of course, the explosion protection rating must match that of the area, and a safety barrier is also required. Flameproof instruments do not require a safety barrier.
The OP’s question is really scary; the temperature is rising~~~~~~~ it’s like roasting a pig.
An intrinsically safe pressure transmitter can be used as an explosion-proof pressure transmitter, but that would be a bit of a waste!
I also think there won’t be any problems. It’s the wrong watch that was bought; otherwise, who would do such a thing?
It’s clearly stated that it’s intrinsically safe and explosion-proof; intrinsically safe designs inherently have a higher safety level than flameproof ones. If flameproof solutions can be used in certain situations, then why not intrinsically safe ones? It can definitely be used! I believe there is no such thing as whether it can be replaced; the question is rather whether it meets the safety standards for use on-site!
But the meter itself is intrinsically safe; there are no intrinsically safe cables or safety barriers. The meter’s enclosure is explosion-proof, so I think it can also be used as an explosion-proof meter. It’s just that the explosion-proof certification does not meet the requirements for true explosion-proof design. These days, certificates are certainly important, right?
Intrinsic safety and flameproofing are both forms of explosion protection; intrinsic safety requires higher standards. It can replace flameproofing, but it would be a waste.
The explosion-proof certificate for this intrinsically safe instrument should be one corresponding to the intrinsically safe explosion-proof rating; this rating is higher than that of flameproof designs, so there’s no such thing as whether it meets the requirements or not! Take an imperfect example: driving licenses of type A and B. Do you think a type A license meets the requirements for a type C license? :sleepy: Waiting for experts to correct me!
