Plug gauge improvement

Our factory is a professional manufacturer of cylinder heads, and the cylinder heads produced are blocked by water. Water plugging holes generally have H8 tolerance requirements. In the quality inspection, because the production batch is relatively large, we generally use plug gauges to check whether it is qualified. In the inspection of the cylinder head product, the pump pressure test found that the water blockage has water leakage. After the water plug is removed, the water plugging hole is qualified by the plug gauge. The inner diameter dial gauge is used to measure the roundness of the water plug hole. Leakage caused by poor sealing indicates that the plug gauge we used has been misdetected.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.

Mass flow transmitter is a micro-programming-centered electronic system, which supplies thrust to sensor, transforms sensor signal into mass flow signal & others, and improves accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display module, etc., installed in a ex-proof junction box. Switching power supply offers power for transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects & processes sensor phase signal, sends mass flow signal and process communication.
