てなることを特徴とする液位伝送器。Pressure-receiving recesses that communicate with the chambers are formed on both sides of a detecting unit main body having a chamber therein, and pressure-receiving diaphragms are provided to block these pressure-receiving recesses, respectively. temperature-compensating pressure receiving elements each adjacent to the pressure receiving diaphragm, each having an inner surface facing a space communicating with the chamber of the main body of the detecting section, and receiving a measurement pressure equal to that of the adjacent pressure receiving diaphragm on each outer surface; A conversion mechanism for converting the pressure difference applied to each pressure receiving diaphragm into an output signal is provided inside the detection body, and a space communicating with the chamber is filled with sealed fluid, and the detection body In a liquid level transmitter, a liquid contact part is provided on one side, the liquid contact part having a liquid contact pressure receiving element and a pressure guiding part for transmitting the pressure applied to the pressure receiving element to one of the pressure receiving diaphragms. ,
Among the pressure receiving elements for temperature compensation, the outer surface side of the pressure receiving element for temperature compensation facing the inside of the liquid contacting part is provided with a structure that allows the pressure receiving element for temperature compensation to deform freely toward the main body of the detection part, and that is in contact with the liquid. A liquid level transmitter characterized by being provided with a stopper that restricts deformation toward the inside of a liquid part.
