01. Application of pressure sensor in weighing system
In industrial control, pressure sensing technology is increasingly being used in commercial weighing systems. In many control processes, it is often necessary to collect pressure signals and convert them into electrical signals that can be automatically controlled, and the pressure control device made with pressure sensors as the core components is generally called electronic weighing system, which is an online control tool for material flow in various industrial processes, and plays an increasingly important role in modern production.
In the process automation control of weighing, the pressure sensor is required to not only perceive the gravity signal, but also its performance must be reliable, the dynamic response must be good, and the anti-interference performance must be good. Through the integration technology, the pressure sensor and the measurement line are integrated, and the signal provided by the pressure sensor can be directly displayed, recorded, printed, and stored by the detection system for feedback adjustment control, so that the degree of automatic control of the weighing process is further improved.
02. Application of pressure sensor in petrochemical industry
Pressure sensors are one of the most widely used measuring devices for 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, micro differential pressure, etc......
The demand for pressure transmitters in the petrochemical industry is mainly concentrated in three aspects: reliability, stability and high precision. Among them, reliability and many additional requirements, such as range ratio, bus type, etc., depend on the structural design of the transmitter, the level of machining technology, and the material of construction. The stability and high accuracy of the pressure transmitter are mainly guaranteed by the stability and measurement accuracy of the pressure sensor.
The measurement accuracy of the pressure transmitter corresponds to the measurement accuracy and response speed of the pressure sensor, and the stability of the pressure transmitter corresponds to the temperature and static characteristics of the pressure sensor and the long-term stability. The demand for pressure sensors in the petrochemical industry is reflected in four aspects: measurement accuracy, fast response, temperature and static pressure characteristics, and long-term stability.
03. Application of pressure sensor in water treatment
China's environmental protection water treatment industry has developed rapidly in recent years, and the future prospects are broad. In water supply and wastewater treatment processes, pressure sensors are relied upon to provide an important means of control and monitoring for system protection and quality assurance.
Water treatment mainly includes water level monitoring of river water conservancy dams, sewage treatment and drinking water treatment, and constant pressure water supply systems. Depending on the installation method of the sensor, it can be divided into built-in type and external type. Among them, the built-in type mainly uses a liquid level transmitter, and the external type mainly uses an industrial pressure sensor.
04. Application of pressure sensors in the medical industry
Pressure sensors play an important role in the examination of medical records of medical patients and the monitoring of minimally invasive surgery, and arterial blood pressure, intracranial pressure, and intrapulmonary pressure are all important parameters in the medical process. In addition, the monitoring, treatment, and health care required for medical care are inseparable from the accurate measurement of pressure sensors.
In addition to sophisticated medical surgery facilities, medical supplies such as electronic blood pressure monitors, which are commonly used in daily life, are also measured autonomously and in real time through pressure sensors.
With the development of modern medical technology, the pressure sensors used in the medical industry have higher requirements in terms of accuracy, reliability, stability, volume, etc., which also promotes the vigorous development of medical pressure sensors.
