Sensor rotation of the shaft of the pump

.

The sensor is used for measuring the flow of liquids pumped by plunger or piston pumps of cementing and other mobile and stationary aggregates.

The sensor has a contactless measurement method, so it can be used with any solutions, including acidic, polymeric, and others. When connected to the microprocessor of the station unit, the sensor provides a chamber method for measuring the flow (GOST 15528-86), which consists of summing up per unit time of the volume of the solution supplied by the pump in one cycle to which a certain number of revolutions of the pump shaft corresponds.

The sensor sensor contains a magnet induction pulse converter. It is installed in a convenient location near the pump shaft shaft and connected by cable to the microprocessor unit or data acquisition device.

The principle of the sensor operation is based on the contactless reading of the magnetic induction device of electrical impulses that arise when magnetic tags pass and proportional to the speed of the shaft and the amount of solution flow generated by the pump.
