Fluke 750PEx is a family of eight intrinsically safe modules for checking pressure instruments in hazardous areas. The 750P01Ex serves low differential pressure, 750P24Ex provides a 15 psi differential range, 750P05Ex–750P29Ex cover gauge pressure, and 750PA4Ex measures absolute pressure. The module receives power from a compatible calibrator and returns digital measurements; it does not generate pressure. Media compatibility and annual uncertainty depend on the exact model. Select connections and accessories according to the FLUKE-750PEX CCD control drawing and current Ex documentation. An order includes one selected module; choose the calibrator and pressure source separately.
