Pressure Switches

Pressure Switch Calibration and Functional Test Ststem
Automatically calibrated and tests a family of pressure switches at a rate of 200 pph.

Features
Calibration Sequence:
• The switch is pressurized to the setpoint pressure (0.5 psig. to 150 psig.).
• The servo ramps up to compress the adjustment spring.
• When the PLC senses the switch transition, the servo reverses motion.
• The servo stops when the transition is sensed again and the switch is vented.

Test Sequence:
• The switch is pressurized to a defined value, either above or below the setpoint.
• The test data will then be written to the Access data base file.
• If the 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 part configuration, call up test parameters and store test data by serial number.
