Pressure Differential Transmitter

What is the definition of a pressure differential transmitter? A pressure differential transmitter is a device used in industrial and commercial facilities to measure the difference between two pressures. This device is used in a variety of applications such as monitoring pressure in pipelines and measuring the flow of liquids and gases through the system. The pressure differential transmitter receives an input signal from a pressure sensor, which is then converted into an electrical signal that can be interpreted by a control system. The transmitter provides an analog or digital output signal to indicate the difference between the two pressures. This signal is then used to adjust the flow of the system or to provide an alarm if the difference is too large. Pressure differential transmitters are typically used in the oil and gas industry, petrochemical industry, and hydraulic systems. They are often used in conjunction with a flow meter to ensure the correct flow of liquids and gases. Pressure differential transmitters are highly accurate and reliable, making them an invaluable tool in ensuring the safe and efficient operation of industrial and
