KJT pressure sensor is able to feel the pressure signal, and in accordance with certain laws will be able to convert the pressure signal into a usable output of the electrical signal of the device or device. Pressure sensors are usually composed of a pressure sensitive element and a signal processing unit. According to different types of test pressure, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. It is widely used in a variety of industrial automation environment, involving water conservancy and hydropower, railroad transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.
