ABSTRACT:
A sensitive to a change in the physical dimension(s) of the exterior surface of a pressure vessel transducer and attached to the exterior surface thereof the pressure vessel may be a vacuum chamber. The transducer measures exterior dimension change, representing interior pressure change information, without intrusion. The measurements are displayed using distinctive lights or audible alarms which signal if the pressure inside the vessel is within a predetermined range. If the pressure within the vessel varies outside of the predetermined range, a more precise display device such as a meter, is provided to aid facility personnel in deciding when repairs are necessary.
