STRAIN-GAUGE PRESSURE TRANSDUCER

摘要

FIELD: measurement technology. SUBSTANCE: transducer has case 6 which accommodates base 3 with membrane-type sensing element 1 and sealed leads 4 and pipe connection 5 with separating membrane 7. Pressure to be measured is supplied through axial hole of pipe connection 5 and separating membrane 7 acting upon dielectric liquid 8 and upon membrane-type sensing element 1 which generates output electric signal corresponding to pressure being measured. Provision for guaranteed clearance between ends of sealed leads 4 and separating membrane 7 be use of case 6 with internal bead, as well as employment of thin flat separating membrane increases conversion accuracy. EFFECT: enhanced reliability in operation. 3 cl, 1 dwgo
