The pressure sensor sales manufacturer tells you the main functions of pressure sensors.

The pressure sensor sales manufacturer tells you that a pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules.

The pressure sensor sales manufacturer tells you that pressure sensors typically consist of pressure sensing elements and signal processing units. Depending on the type of pressure being tested, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are commonly used in industrial practices and are widely applied in various industrial automation control environments, involving industries such as hydropower, railway transportation, smart buildings, production automation control, aerospace, military, petrochemical, oil wells, electricity, shipping, machine tools, and pipelines. Here, we briefly introduce the principles and applications of some commonly used sensors. There are also medical pressure sensors.

Heavy-duty pressure sensors are one type of sensor, but we rarely hear about them. They are typically used in transportation applications to maintain the performance of heavy-duty equipment by monitoring the pressure, fluid force, flow, and liquid levels of critical systems (such as pneumatic, light-load hydraulic, brake pressure, oil pressure, drive systems, and air brakes of trucks/trailers).

The pressure sensor sales manufacturer tells you that heavy-duty pressure sensors are pressure measurement devices with a housing, metal pressure interface, and high-level signal output. Many sensors are equipped with round metal or plastic housings, which are cylindrical in appearance. One end has a pressure connection, while the other end has a cable or connector. These heavy-duty pressure sensors are typically used in extreme temperature and electromagnetic interference environments. Customers in the industrial and transportation sectors use pressure sensors in control systems to measure and monitor the pressure of fluids (such as coolants or lubricants). At the same time, they can also detect pressure spikes in a timely manner, identify issues such as system congestion, and find solutions promptly.

Heavy-duty pressure sensors have been evolving. To be used in more complex control systems, design engineers need to improve the accuracy of the sensors and reduce the costs of practical applications. The main piezoelectric materials used for piezoelectric sensors include quartz, sodium potassium tartrate, and diammonium phosphate. Among them, quartz (silicon dioxide) is a natural crystal that exhibits the piezoelectric effect. The piezoelectric properties persist within a certain temperature range, but beyond this range, the piezoelectric characteristics completely disappear (this high temperature is known as the "Curie point"). Due to slight variations in the electric field with stress (i.e., the piezoelectric coefficient is relatively low), quartz has gradually been replaced by other piezoelectric crystals. Sodium potassium tartrate has high piezoelectric sensitivity and coefficient but can only be used at room temperature and low humidity. Diammonium phosphate is a synthetic crystal that can withstand high temperatures and high humidity, thus finding widespread application.
