摘要:
A pressure pickup includes a pressure measuring cell and a platform through which a pressure canal equipped with a flame penetration barrier extends. The pressure measuring cell is loadable with the process pressure through the pressure canal by means of a transmitting medium. The pressure canal includes a first section and a second section, with the flame penetration barrier being arranged in a first section, and a second section has a bore, in which a fill-body is arranged. The gap between the bore and the fill-body is manufactured with greater tolerances, so that it does not fulfill the requirements for a flame penetration barrier. The flame penetration barrier is realized in the first section, for example, by providing in the first section a bore, in which a fill-pin is arranged, with the remaining gap between the bore and the fill-pin satisfying the requirements for a flame penetration barrier.
