What is the leading ignition protection type for UHP pressure transducers?
Fabian Mayer | Know-howThe leading ignition protection type is critical for the electrical connection of a pressure sensor with explosion protection. It does not necessarily have to be the one with the stricter requirements. This applies, for example, for the UHP pressure transducers of the …
Flame arrester protects sewage vacuum truck tanks
Jing Lyu | ApplicationsA pre-volume deflagration flame arrester or – simplified – a flame arrester prevents flame transmission, through a measuring instrument, into a zone 0 (gas) hazardous area. This protective function, therefore, plays an important role, especially in process …
