FIELD: measurement.
SUBSTANCE: invention relates to measuring equipment, namely to electromechanical devices intended for switching electric circuits when pressure reaches a given setpoint operation, and is a pressure indicator. Soft corrugated membrane on a shaped lodgement and a welded bellows are hermetically installed in the housing of the pressure indicator. Volume formed by the membrane and the bellows is filled with liquid. Bellows rests against the contact system, which is a piston pressed by two compression springs, moving progressively and closing and opening pairs of contacts by a flat contact spring connected to it. Compression springs can be adjusted by means of adjusting nuts, which makes it possible to change the actuation setting and the differential between actuation and release.
EFFECT: possibility to adjust settings and differential.
