FIELD: instrumentation.
SUBSTANCE: in the vertical wall of the support of the mechanical value sensor there is a horizontal blind hole in the shape of a straight cylinder, forming the appearance of a glass; an elastic three-layer plate is rigidly embedded in its thick bottom, the middle layer of which consists of an electrically insulating material and is hermetically sealed with two metal layers; a separating membrane made of elastic electrical insulating material is glued to the outer edge of the glass along the contour and part of the plate and a protective cover is attached; the glass is completely filled with electrolyte, forming a common electrochemical cell with the two metal layers of the plate.
EFFECT: increase in the reliability of operation and reliability of measurements of the device.
