FIELD: measuring engineering.
SUBSTANCE: device comprises air unit provided with inlet chamber, measuring chamber with inlet and outlet nozzle and measuring nozzle, chamber for counterpressure with the inlet nozzle and counterpressure valve, sensor made of a diaphragm with pneumoelectric converter and flowing passage, and unit for processing information. The value of the bend of the diaphragm is measured by means of pneumoelectric converter with supply of the electric signal to the unit for processing information that displays the results of measurements on the screen. The device also has two temperature sensors connected with the unit for processing information. One of the sensors is positioned directly in the zone of the member to be measured, and the other sensor is positioned in the working zone of the measuring instrument on the measuring table. The temperature sensors send the signal to the unit for processing information to correct the readings and to reduce the results of measuring to normal conditions (20°).
EFFECT: enhanced efficiency and accuracy of measuring.
