Electromagnetic monitoring on-line oil metal abrasive particle sensor calibration and metering system

The utility model relates to an electromagnetic monitoring on-line oil metal abrasive particle sensor calibration and metering system which comprises a sample ingress pipe, a feeding push rod is arranged on the rear side of the ingress pipe, the feeding push rod points to an air blowing port and sends a verification ball loaded by the sample ingress pipe to the air blowing port, the air blowing port is connected with one end of a ball guide pipe, an air valve is arranged at the air blowing port, and the ball guide pipe is connected with the air valve. A photoelectric sensor is arranged on one side of the ball guide pipe, and the verification ball penetrates through the ball guide pipe through air flow provided by the air valve and is captured and recorded by the photoelectric sensor when passing through the ball guide pipe. The other end of the ball guide pipe is connected with a verification ball storage guide pipe, a sensor is fixed between the sensing installation block and the verification ball storage gu
