FIELD: measurement technology.
SUBSTANCE: invention refers to the sphere of pressure measurements, in particular, for the calibration and standardisation of manometres. The device for calibration of manometres consists of control device, collector for connection of standard instrument and manometres to be calibrated and connected to the tank with liquid and to the device to create the pressure. The device is made in the form of cylinder with plunger kinematically connected by the transfer screw-nit rolling to reduction gearmotor electric motor whereof is equipped with the brake and is electrically connected to the control device. In the pipe between cylinder and tank the back-pressure valve is installed.
EFFECT: simplification of construction of the device during automation of the calibration process.
