Remote Diaphragm Application in Pressure transmitter housing
Release time:
2022-04-12
Application of remote diaphragm. Taking a pressure transmitter as an example, a pressure transmitter with a remote diaphragm is mainly composed of a pressure transmitter, a Pressure transmitter housing, a remote diaphragm, a process connection and a capillary. In general, this kind of Pressure transmitter housing with a remote diaphragm should be used as little as possible. The high precision and high stability of various transmitters are only for single transmitters, but there are no exact application indicators for Pressure transmitter housing with capillary tubes.

In industrial measurement, the use of pressure transmitter housing with remote diaphragm is common in the following conditions: in high temperature applications without using ordinary pressure piping to cool down, the high temperature medium is isolated from the transmitter; the measured medium is opposite to the transmitter. The wetted part of the transmitter has a corrosive effect, especially the diaphragm of the Pressure transmitter housing sensor; the measured medium is highly viscous or easy to solidify or crystallize due to changes in the environment, process, and temperature; measurement of container liquid level; liquid density Or it is liquid/liquid interface measurement; the process requires that the container or pipeline to be measured should reduce dead angles as much as possible; it is not desirable to have a pressure-inducing pipeline that enters the medium.
Through the above introduction and analysis of Pressure transmitter housing, hope it helps you.
