Pressure transducer and method of making same

摘要

A hydraulic pressure transducer comprises a cylindrical housing having a plurality of circumferential inwardly and outwardly directed ribs which axially position and retain coaxially aligned operative components within the transducer. These components include a hydraulic piston and cylinder, a restoring spring disposed between two centering and retaining stabilizer cups, and a biasing spring which maintains the components in compressed juxtaposition to ensure accurate and immediate response while minimizing axial dimensional stack up. The transducer senses hydraulic pressure in, for example, a brake line and provides a variable resistance output which may be used in an auxiliary electric brake system controller commonly used on recreational trailers and the like.
