The pressure transducer is a device or device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, hvac differential pressure sensor and absolute pressure sensors. The pressure sensor is usually composed of a pressure sensitive element and a signal processing unit.
Recently, ASIC special integrated circuits are used to encapsulate sensors, microprocessors and network interfaces in one device to complete the functions of information acquisition, processing, transmission, and storage. The pressure transducer transmitter is widely used in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries. Pressure transducer made by pressure switch manufacturer tries to meet the requirements of centralized detection and control of automation systems, and is therefore widely used in industrial production.
1. The role of pressure transducers in industry
In industrial process control, computer technology has been relatively mature, and the information that needs to be collected is increasing. The production process requires a large number of types of pressure sensor, such as pressure sensors, thermal sensors, light sensors, gas sensors, humidity sensors and magnetic sensors, etc., to convert a large number of non-electricity physical and chemical parameters into electrical signal control information to meet the needs of various industries. The development needs of automation and intelligence in the process. The high precision of the pressure transducer and its ability to measure absolute pressure, gauge pressure and differential pressure make it widely used in various applications. For industrial equipment and machinery, the information provided by pressure sensors can be used to most effectively operate hydraulic or pneumatic equipment, and then be linked with the new Industry 4.0 standards. And there are more and more
2. Application examples of pressure transmitters
Waste sorting and resource recycling have become part of our lives today, which can reduce waste of trees and oil. In many communities, there are waste recycling smart cabinets. We scan the QR code, select the type of waste, and open the corresponding cabinet door. We put a bag of plastic bottles in, and the device automatically closes the door. The equipment inside automatically compresses and compacts the waste products so that more waste products can be placed. A pressure sensor is used here, and it stops when it detects that the pressure is greater than the set value, so as to ensure that the pressure is moderate.
