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. This measurement is vital for a wide range of applications such as flow measurement (using the principle of differential pressure across an orifice plate, Venturi tube, etc.), level measurement in tanks, and detecting clogging in filters. DP transmitters convert the measured differential pressure into an electrical signal (usually 4 - 20 mA) that can be easily processed and monitored by control systems. Their accuracy and reliability are of utmost importance in ensuring the safe and efficient operation of industrial processes.
