PRESSURE AND TEMPERATURE-SENSITIVE ELEMENT Russian patent published in 2005 - IPC

FIELD: radioelectronics.

SUBSTANCE: pressure and temperature-sensitive element has case where T-joint is installed. T-joint has dielectric insertion inside through channel. Sensitive element in form of ferrite pipe is mounted onto inner surface of insertion and first inductance coil is made onto outer surface of insertion. Sensitive element made in form of bellows is fastened to edge of side tap of T-joint with its open side. Closed edge of bellows is fastened to tow-bar that moves reciprocal adjusting element made in form of a core. Core is mounted aligned in the second inductance coil. Ends of both coils are connected to output anti-rod converters of reflecting delay line. Converters are located at different distances from input anti-rod converter provided with transmitting aerial.

EFFECT: improved precision of contact-free measurements.
