LEVERLESS PRESSURE TRANSDUCER

摘要

LEVERLESS PRESSURE TRANSDUCER A temperature or pressure sensor that produces a hydraulic pressure signal proportional to temperature or pressure. The sensor or transducer utilizes a plurality of bellows acting on a valve nozzle plate so that the temperature signal which is a gas pressure moves the nozzle plate to control the flow through the nozzle as a function of temperature thus producing a metered pressure proportional to temperature. The bellows are arranged to minimize temperature error in the transducer. Where the temperature sensed is engine inlet temperature the metered pressure may be used to control the fuel through the turbine engine as a function of the engine inlet temperature. This same device is equally utilized in measuring a pressure, such as compressor discharge pressure. H808-CC
