FIELD: measurement equipment.
SUBSTANCE: mark is applied onto the centre of the membrane. The sensor is fixed in a hole of a massive base, perpendicularly to the surface of which there is a stand installed with a fixed holder, comprising a lower part and an upper part connected to each other in a fixed manner. A clock-type indicator is fixed in the upper part of the holder so that its longitudinal axis matches the longitudinal axis of the surveyed sensor and the centre of the membrane. In the base there is a hole for fixation of a pressure supply device, besides, holes for fixation of the sensor and the pressure supply device are connected to each other with a through hole.
EFFECT: increased accuracy of membrane sagging measurement and reduced error of a pressure sensor.
