Tips: What is a differential pressure transmitter mainly used for?
A differential pressure transmitter is a type of sensor, primarily used to measure the difference in pressure between two points in a system. It's widely employed in industrial processes to monitor and control variables such as liquid levels, flow rates, and fluid densities. The device senses the pressure variance across two ports and converts this information into an electrical signal, typically a 4-20 mA current loop or voltage output, which is proportional to the measured pressure difference.
Common applications include monitoring filtration processes, measuring liquid or gas flow rates, and ensuring precise control in HVAC systems. In the petrochemical industry, it is utilized for monitoring pressure imbalances in pipelines. The versatility of differential pressure transmitters makes them essential in various sectors, contributing to efficient and reliable process control and ensuring the safety and performance of industrial systems.
