The purpose of our project is to design, build and test a machine to automatically test hydraulic pressure transducers. This machine will then generate a statistical analysis report on the test results. The system generates its pressure using a standard motorsport master cylinder. This master cylinder is linearly driven by a mini jack screw system. This mini jack screw is activated with a stepper motor. The pressurized hydraulic fluid is transferred through a steel braided line into a custom pressure rail that the transducers are placed in for testing. This pressure rail also includes a port for a pressure relief valve, bleed screw and mechanical pressure gauge, to increase the safety of the device’s operator. The system is electrically powered with a 120 VAC wall outlet which is supplied to an AC to DC converter to achieve 24 VDC. This 24 VDC signal is connected to the stepper motor driver as well as a custom PCB daughter board. On said daughter board the 24 VDC signal is converted to 5 V and 3.3 V signals to power the control circuit, driven by an ESP microcontroller. This system is also integrated with Racing Tech’s web server management system.
