Introduction to DP Transmitter
A differential pressure (DP) transmitter is a crucial instrument widely used in various industrial processes. It measures the difference in pressure between two points and converts this differential pressure into an electrical signal (such as 4 - 20 mA) that can be easily read and processed by control systems. DP transmitters find applications in industries like oil and gas, chemical, power generation, water treatment, and many others. They are used for flow measurement, level measurement, and density measurement, among other functions. By accurately measuring the differential pressure, these transmitters help in ensuring the efficient and safe operation of industrial processes.
