Top 10 dp transmitter Suppliers in the world 2025

Introduction to DP Transmitter

A differential pressure (DP) transmitter is a crucial instrument in the field of industrial automation and process 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 a digital signal). This signal can then be used to monitor and control various processes, including flow measurement, level measurement, and density measurement. DP transmitters are widely used in industries such as oil and gas, chemical, power generation, water treatment, and food and beverage.
