FIELD: instrumentation engineering. SUBSTANCE: pressure transducer has case incorporating two separated spaces (intake and converter of movement of sensitive element), rod which lower end is joined to bellows and in which upper part bushing with flange is mounted on protrusion. On bearing surface of flange there is positioned bushing with internal thread into which lower end of spring of sensitive element is screwed. Second bushing rests against upper supporting plane of spring between butts of bushings and planes of end cap joined permanently to second bellows. There are arranged adjustable clearances.
