When compared to pressure sensing diaphragms, capsules show two times the deflection relative into the applied pressure. There are actually 3 different types of pressure sensing capsules: one capsule, stacked capsule, and profiled capsule. A standard resonant wire pressure transducer includes numerous parts including: Resonant wire Substantial-pressure diaphragm Minimal-pressure diaph... https://controltechme.com/pressure-transducers/
