FIELD: physics; electricity. ^ SUBSTANCE: production of piezoelectric pressure transducer includes as follows. Piezoelectric elements 1 with electrodes 2, insulators 3, thin-walled casing 5 and force transmitting element 6 are mounted on foundation 4 which contains process body 7 as well. All assembly components of sensitive element with force P are tighten in thin-walled casing 5 perimeter mating from one end face with force transmitting element 6, and from another with foundation 4. For ease of mating in lower part of process body 7 grooves 8 are provided. After thin-walled casing is mated with details 4 and 6, process body is removed. Sensitive element is mounted in sensor body; sensor internal cavity is hermetically sealed with body welding to foundation. ^ EFFECT: higher accuracy of measurement and mechanical reliability of sensors. ^ 2 dwg |
