FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, namely, to pressure sensors. Proposed differential pressure sensor with support on tension section with self-centering system contains external and internal bases, on which external and internal rollers or rotation sprockets, respectively, are fixed, connected by successively closed cable, chain or belt, wherein inner base is made with possibility of applying to it first pressure force, additionally rollers are introduced, through which springs provide cable tension, chain or belt, additionally roller is introduced, to which second pressure force is supplied via union and bellows, applied to cable, to chain or belt, wherein differential pressure sensor is made with possibility to convert internal base displacement into gear wheel rotational movement, connected to pointer.
EFFECT: technical result is increased accuracy of pressure measurements.
