Pressure-Decay Leak Tester

Approx. component budget: Rs. 5,000 - 9,000

Objective

Detect and measure leaks in sealed parts such as bottles, caps and small housings using the pressure decay method.

What you will build

A test chamber with fixtures, a regulated air supply, a precision pressure sensor, a solenoid valve and an Arduino that fills, holds and measures the pressure drop.

Results you can expect

• Pressure vs time curves for good and leaking parts
• Leak rate estimate
• Pass/fail limit
• Repeatability over 20 samples

What you will learn

Leak testing, pressure sensing and test automation, used in packaging and automotive quality control.

Tools and notes

Pressure sensor, solenoid valve, Arduino, Excel. Test at low pressure and only on parts rated for it. Wear eye protection.

Resume points from this project

• Built and tested Pressure-Decay Leak Tester; objective: detect and measure leaks in sealed parts such as bottles, caps and small housings using the pressure decay method.
• Measured and analysed pressure vs time curves for good and leaking parts and leak rate estimate; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
