Understanding Differential Pressure Transmitters: A Guide for 4-20mA China Companies

Differential pressure transmitters are an important component of many industrial systems, and are used to measure the difference in pressure between two points. As such, they are essential for monitoring and controlling the pressure of liquids and gases in a variety of applications. For 4-20mA China companies, understanding the different types of differential pressure transmitters and their features is essential for selecting the right product for their needs. The most common type of differential pressure transmitter is the diaphragm-based transmitter. This type of transmitter uses a diaphragm to measure the difference in pressure between two points. The diaphragm is connected to a sensing element, which is then connected to a transducer. The transducer converts the pressure difference into an electrical signal, which is then sent to a controller or display. Diaphragm-based transmitters are typically used in applications where the pressure difference is relatively small, such as in HVAC systems. Another type of differential pressure transmitter is the capacitive-based transmitter. This type of transmitter uses a capacitive sensing element to measure the difference in pressure between two points. The capacitive sensing element is connected to a transducer, which converts the pressure difference into an electrical signal. Capacitive-based transmitters are typically used in applications where the pressure difference is relatively large, such as in oil and gas pipelines.

Finally, there are also differential pressure transmitters that use a combination of diaphragm and capacitive sensing elements. These transmitters are typically used in applications where the pressure difference is both large and small. For 4-20mA China companies, understanding the different types of differential pressure transmitters and their features is essential for selecting the right product for their needs. Differential pressure transmitters are available in a variety of sizes and configurations, and can be used in a variety of applications. By understanding the different types of transmitters and their features, 4-20mA China companies can ensure that they select the right product for their needs.
