Introduction to DP Transmitter
A differential pressure (DP) transmitter is a crucial instrument in the field of industrial measurement and control. It measures the difference in pressure between two points in a system and converts this differential pressure into an electrical signal (such as 4 - 20 mA or digital signals). DP transmitters are widely used in various industries, including oil and gas, chemical, power generation, water treatment, and HVAC systems. They play a vital role in processes such as flow measurement, level measurement, and density measurement. By accurately measuring differential pressure, these transmitters help ensure the safe and efficient operation of industrial processes.
