To obtain a remote seal type differential pressure transmitter that can easily remove and exchange each component in an apparatus and at the same time can cope with also a diversified flange standard.

In the remote seal type differential pressure transmitter for transmitting pressure from a process to the differential transmitter via the pressure reception section of a block and a flange, a capillary tube for transmitting pressure that is received by the pressure reception section to the side of the differential pressure transmitter by sealed oil, and an integration-type stay flange that is fixed to the block and at the same time the diaphragm seal type differential pressure transmitter are provided for forming a diaphram seal type differential pressure transmitter.
