LOW PRESSURE PNEUMATIC PULSE LOGGING SENSOR Russian patent published in 2020 - IPC G01L23/16 G01R5/02 

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to control and measurement equipment and can be used in automated control and measurement control systems. Disclosed is a sensor for detecting low-pressure pneumatic pulses, comprising a sensitive element in form of a plate which responds to pressure change of the pneumatic pulse, and a measurement circuit consisting of a magnetoelectric galvanometer, comprising a current frame placed in the gap of the permanent magnet, mirror, light source, condenser, diaphragm, and electric bridge circuit including differential photoresistor, reference and adjustment resistor, voltage source, in feedback of which there is load resistance and recording device.

EFFECT: providing high sensitivity and response parameters when determining pressure in dynamic processes owing to use of said sensitive element.
