差圧伝送器。The chambers formed in the body are divided into two chambers A and 2 by a diaphragm.
The chamber A is connected to one side of the pressure sensor and the chamber B is connected to the opposite side of the pressure sensor, so that chamber A is connected to one fluid source and chamber B is connected to the other fluid source. At the same time, connect two shutoff valves to the diaphragm,
When the pressure on the side of chamber A is higher than the pressure on the side of chamber B by a certain value or more, one of the shutoff valves closes off between chamber A and the fluid source, and conversely, the pressure in chamber B is kept constant than the pressure in chamber A. When the pressure on both sides of the diaphragm is exceeded, the other shutoff valve is used to close off the chamber B and the fluid source, and a safety valve is installed on the diaphragm to open both sides of the diaphragm. A differential pressure transmitter in which the safety valve is opened by displacement when the difference is greater than a certain value.
