The pressure sensor (pressure transducer) is a device or device that can feel the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule.

The pressure sensor is usually composed of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

The pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil well, electricity, ships, machine tools, Pipelines, and many other industries

Application of pressure sensor in the petrochemical industry

The pressure sensor is one of the most used measuring devices in automatic control in the petrochemical industry. In large-scale chemical projects, almost all pressure sensor applications are included: differential pressure, absolute pressure, gauge pressure, high pressure, slight differential pressure, high temperature, low temperature, and remote flange pressure sensors of various materials and special processing. Almost the petrochemical industry's demand for pressure sensors is mainly concentrated in three aspects: reliability, stability, and high precision. Among them, reliability and many additional requirements, such as turndown ratio, bus type, etc., depending on the transmitter's structural design, mechanical processing level, and structural materials. The stability and high accuracy of the pressure transmitter are mainly guaranteed by the stability and measurement accuracy of the pressure sensor.
