Leak Detection Through Pressure Decay
Method 1: Diagram 1 shows a plastic container being tested utilizing a gage type transducer. If the container is pressurized to 100 psi and then the valve is closed, the transducer will sense a leak/decay in pressure in the container, if given enough time. Small leaks can be detected in this manner, although the process can be time consuming.
