CLOSED-TYPE PRESSURE TRANSDUCER

摘要

The present invention relates to a pressure transducer for monitoring pressure which can sense a minute pressure change by sensing a pressure change by injecting oil inside a space formed by closing one side of a housing unit and transmitting external pressure to a sensor via the oil; of which an error range of measuring pressure is little even though a temperature change range is wide; which includes the pipe-shaped housing unit with a blocking unit which blocks a middle part of a cavity, a thin film unit which is joined to one side of the housing unit and on which external pressure is applied; and a sensing unit which is installed on the inside of the other side of the housing unit and which senses the pressure applied to one side of the housing unit.
