摘要

FIELD: electricity.;SUBSTANCE: jumper cable of the pressure sensor is made as four copper silver-plated current-carrying conductors shielded collectively, twisted and electrically insulated by fluoroplastic or polyamide. At the lateral side of a cylindrical body between the butt end of a coupling nut and the butt end of a thread bushing there are six grooves similar in size and configuration, which form three pairs of grooves. Lateral surfaces of each groove are parallel to each other and symmetrical to the plane passing perpendicular to the longitudinal axis of the cylindrical body through the midway between butt ends of the coupling nut and thread bushing. Width of the grooves is equal to distance between butt ends of the coupling nut and thread bushing while length of the grooves is made in compliance with a certain ratio.;EFFECT: reducing error of the pressure sensor at impact of high vibratory accelerations and wide range of transient temperatures of environment, reducing warm-up time upon voltage supply and increasing temporary stability of the sensor.;2 dwg
