Washing Machine Water Level Sensor Test, each test station uses quick clamping to fix the samples, and uses SMC electronic proportional 0-200Kpa adjustable air pressure to adjust the simulated air pressure. The low water level and high water level are set for 0-30 times/ high frequency on-off test. And the PLC control software detects the ON/OFF state of the water level sensor in real time. Record the relevant aging test times and the and unqualified judgment of the product. The relevant test data can be exported through USB. Washing machine water level sensor test bench.

The main components of the test bench are follows:

1. The main components of the test bench are mainly composed of test machine frame, automatic pressure regulating air supply device, two-pin/three-pin on- signal board acquisition, control system, etc.

2. The test main support is made of aluminum profile assembly, and the outer box is made of spray powder sheet metal as the enclosure of the equipment cabinet. The bottom of the machine frame is a universal foot wheel, which is convenient for equipment movement and transportation.

3. The control system is a selfdeveloped control system, using Japanese Mitsubishi PLC control, 10-inch touch screen display related test content and control. Through program control, the low and high water level of the tested washing machine are subject to long-term on/off life test. PLC real-time monitoring of each test water level switch running on-off signal whether works normally, manual quick installation, one-key start test mode.
