Project Overview
The current hydrostatic test apparatus is manually controlled and needs to be redesigned so that the test can run automatically using a digital interface. The pressure, ramp rate, and hold time are all automatically controlled within the system so that an electrical enclosure can be
tested up to 10,000 psi, safely.

New System Components•Needle Valve•Stepper Motor and Encoder•Ball screw•Manifold with Pipes•Pressure Transducers•Enclosure•NI-cRIO-9075
System Automation
● Pressure Feedback from transducers.● Control effort generated via PID controller.● Control effort dictates stepper motor clock
duty cycle and direction.● Finite state machine used to program DAQ.
Product
Controller Graphical User Interface
Project Status
● Currently a majority of the system is at Cooper Crouse-Hinds waiting to be installed.
● Electrical system is waiting on the completion of the piping install and the O.K. from Cooper.
● Controller software is fully programed and ready for onsite testing.
Schedule
Project Delays1. Ordered the wrong motor (too large, missing a second shaft for encoder) - 1 WEEK
2. Valve took 11 weeks to arrive instead of 10 - 1 WEEK
3. Valve was linearly actuated, not rotationally- 2 WEEKS
4. Connecting DAQ to lab computer- 2 WEEKS
5. DAQ programming delays/problems/seeking help- 2 WEEKS
6. Installation at Cooper- Delivered System structure 5/1/14
BudgetBudget = $6,000
Key Components = $3,975.69Hardware = $1,202.32
Travel Expenses = $100.00
Total Spent = $5278.01
Unresolved IssuesOutstanding Items:
● Deliver Electrical System with Procedural and Maintenance Manual
● Install motor/gearbox to ballscrew assembly
● Install door on enclosure
● Run tests to qualify our system’s requirements
