METHOD OF CONTACT PRESSURE MEASUREMENT BETWEEN TWO INTERACTING HARD AND ELASTIC PRODUCT COMPONENTS AND RELATED DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2009 - IPC G01L19/12 

FIELD: physics, measurement.

SUBSTANCE: invention can be applied in various manufacturing industries of products containing two interacting elements one of which is hard, and another is elastic. Product is connected to measuring (hydraulic) and signal (electric) circuits of the device. For this purpose the product is attached through electric-to-hydraulic pressure transducer (EHPT) and the pipeline to hydraulic ram containing technological fluid. To connect the product to signal circuit, electric circuit is looped with one terminal directly on hard component and with the other terminal connected to EHPT core on elastic component. Transducer contact bar is reset. Electric circuit is looped and contact is registered with the indicator. Then hydraulic ram piston actuates pressure of environment delivered to EHPT cavity. As soon as elastic component detaches from the bar under pressure, electric circuit is interrupted, and the indicator generates proper signal.

EFFECT: higher accuracy and reliability of measurements, as well as expansion of functionality.
