Service intended
P542 and P543 series are designed for a local reading of measured pressure and equipped with the electrical contact block which allows all the combinations of contacts to be used. The contact block is mounted on the dial. The window is fitted with a knob for external adjustment of the set points. These are also designed to direct the leakage of insulating oil inside the electric cable.
