Sensors that can convert pressure into electrical output are often called pressure sensors. The pressure sensor is composed of elastic sensor and displacement sensor. The function of the elastic sensor is to make the measured pressure act on a certain area and convert it into displacement or strain, and then convert the displacement sensor or strain gauge into an electrical signal which has a certain relationship with the pressure.

 

Pressure sensors can be used to automatically monitor pressure levels in pneumatic systems, or for more sophisticated monitoring functions, in air, water, hydraulic, or any number of fluid conditions. At the same time, the pressure sensor is widely used in a variety of industrial automatic control environment, involving water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipelines and other industries.

 

Modern industrial equipment

 

Pressure sensing technology is critical when pressure monitoring is used for plant safety, or in applications that require a high level of functional pressure control. Pressure sensor is an indispensable part of industrial equipment, such as the increase of the necessary sensor, its function and accuracy can be improved, easy to operate and maintain, safety level can also be improved, equipment can be added value; Industrial equipment as an automation system control object or as a part of the automation system, must be able to be compatible with the three parts of the automation system (detection, control, execution) or provide an interface, so that the integration of an organic whole, whether stand-alone automation or as a part of a large automation device, to expand the use of the industrial equipment. To sum up, the increase of sensors in industrial equipment is a necessary condition for equipment upgrading.
