Acoustic technology is used to measure pressure or vacuum in containers with metal closures that do not have a measurable lid deflection. The sensor works by applying a “dong”to the top of each container lid using an electromagnetic pulse which excites the closure.The lid vibrates at a natural resonant frequency “dong” based on internal pressure or vacuum. The resultant “do” signal is sensed by a microphone. The Digital Signal Processor (DSP) produces a real-time signal
