Abstract
In a differential pressure transmitter, the respective measurement pressures are applied to a pair of barrier diaphragms respectively disposed on both side surfaces of a body, and movement of a sealed liquid caused by a differential pressure thereof is extracted as an electrical output by a differential pressure measuring pressure sensor provided by partitioning a sealing circuit. A sensor housing is manufactured independently of the body. The differential pressure measuring pressure sensor and a static pressure measuring pressure sensor for measuring a static pressure when applied with a measurement pressure applied to one of the pair of barrier diaphragms and a reference pressure such as an atmospheric pressure, are disposed in the housing. The housing is fixed to a housing mount portion of the body.
