To reliably compensate for a zero point after assembling by arranging a means for displacing a high pressure side or low pressure side pressure receiving diaphragm by prescribed quantity by moving a high pressure side or low pressure side pressure transmitting medium.

A differential pressure transmitter with a remote seal diaphragm has, for example, a pressure receiving diaphragm displacing means 15. A pressure transmitting medium sealed in a high pressure side pressure receiving part and a low pressure side pressure receiving part of the differential pressure transmitter expands or contracts by an ambient temperature change, and this expansion quantity or contraction quantity is absorbed by displacement of a pressure receiving diaphragm, so that output differs. A difference in this output can be reduced by displacing a high pressure side pressure receiving diaphragm by moving, for example, a high pressure side pressure medium 13 by the pressure rceiving disphragm displacing means 15, thereby compensates for a difference in zero point output of differential pressure by an ambient temperature change. A means by a screw plug and a valve mechanism is used as the pressure receiving diaphragm displacing means 15.
