What is differential pressure transmitter?
The differential pressure transmitter is used to prevent the medium in the pipeline from directly entering the transmitter, and the pressure-sensitive diaphragm and the transmitter are connected by a capillary filled with fluid. It is used to measure the level, flow and pressure of liquid, gas or steam, and then convert it into a 4-20mA DC signal output. The cover of the picture shows the 3051 differential pressure transmitter of the domestic brand.
The differential pressure transmitter is suitable for the following measurement and control situations:
●Viscous medium at high temperature
●Easily crystallized medium
●Precipitating medium with solid particles or suspended matter
●Strong corrosive or highly toxic medium
It can eliminate the phenomenon that the pressure guiding tube leaks and pollute the surrounding environment; it can avoid the tedious work of frequently supplementing the isolating liquid due to the unstable measurement signal when the isolating liquid is used.
●Continuous and accurate measurement of interface and density
The remote transmission device can avoid the mixing of different instantaneous media, so that the measurement result truly reflects the actual situation of the process change.
●Occasions requiring high sanitation
For example, in the production of food, beverage and pharmaceutical industries, not only the parts of the transmitter contacting the medium are required to meet the hygienic standards, but also it should be easy to wash to prevent cross-contamination of different media.
