　　Pressure sensor sales manufacturerTell you the working principle of pressure sensors

The pressure sensor sales manufacturer tells you that the heavy-duty pressure sensor is one of the sensors, but we rarely hear about it. It is usually used in transportation applications to maintain the performance of heavy-duty equipment by monitoring the pressure, fluid force, flow, and liquid level of critical systems (such as pneumatic, light-load hydraulic, brake pressure, oil pressure, drive systems, and air brakes of trucks/trailers).

　　Pressure sensor sales manufacturerThe heavy-duty pressure sensor is a pressure measuring device 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 connector, and the other end has a cable or connector. This heavy-duty pressure sensor is 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 coolant or lubricating oil). At the same time, it can also detect pressure spikes in a timely manner, identify issues such as system congestion, and find solutions promptly. Currently, the piezoelectric effect is also applied to polycrystals, such as current piezoelectric ceramics, including barium titanate piezoelectric ceramics, PZT, lead niobate piezoelectric ceramics, and lead niobate magnesium piezoelectric ceramics.

The piezoelectric effect is the main working principle of piezoelectric sensors. Piezoelectric sensors cannot be used for static measurements because they can only save the charge after external force is applied when the circuit has infinite input impedance. This is not the case in practice, so piezoelectric sensors can only measure dynamic stress. Piezoelectric sensors are mainly used for measuring acceleration, pressure, and force.

The piezoelectric accelerometer is a common type of accelerometer. This utility model has advantages such as simple structure, small size, light weight, and long service life. The piezoelectric accelerometer has been widely used in vibration and impact measurements of aircraft, automobiles, ships, bridges, and buildings, especially in the aerospace field. Piezoelectric sensors can also be used to measure the internal combustion pressure and vacuum of engines. They can also be used in the military industry, for example, to measure changes in chamber pressure during firing and shock wave pressure at the muzzle. They can be used to measure both high and low pressures. Piezoelectric sensors are also widely used in biomedical measurements. For example, ventricular catheter microphones are made of piezoelectric sensors. Due to the commonality of measuring dynamic pressure, piezoelectric sensors are widely used.

In addition to piezoelectric sensors, there are also piezoresistive sensors made from the piezoresistive effect, and strain-type sensors that use the strain effect. These different pressure sensors use different effects and materials, and can play their unique roles in different situations.
