Abstract:

In order to solve the problem of the devices fragile and inaccurate data measurement, detection mode of dualchannel “and” relationship criterion and signal timing logic is presented. The system has four modes, each mode the double inductive sensor signal acquisition can effectively improve the durability of the sensor to protect the accuracy of the detection signal. Testing equipment has accurate test results, touch-screen real-time control parameters, durable and strong cost, with a high market value.

Key words: sensor, programmable logic control, dual-screen, real-time data display
