Functional Testing Equipment for Pressure Switch Manufacturing

InterTech’s functional pressure switch tester delivers maximum efficiency for either 100% test production lines or in the laboratory to meet audit requirements.

Pressure Switch Functional Test System and Fixture

 

Features

Calibration Sequence:
    • The switch is pressurized to a set-point pressure (0.5 psig. to 150 psig.).
    • A servo ramps up to compress the adjustment spring.
    • When the PLC senses the pressure switch transition, the servo reverses the motion.
    • The servo stops when the transition is sensed again and the switch is vented.
Functional Test Sequence:
    • The switch is pressurized to a defined value, either above or below the set-point.
    • The functional test data is written to the Access database file.
    • If the pressure switch transition is within tolerance, the part is vented and unclamped.
    • A reject remains clamped until the operator presses the reset button. The MMI provides a real-time display of test cycles, test data, statistics, and machine status.
    • Barcode input prior to cycling is used to automatically verify the part configuration, call up test parameters and store test data by serial number.
