What are pressure sensors produced by manufacturers that sell pressure sensors?

  Pressure sensor sales manufacturerThe pressure sensors produced are used in hydropower, railway transportation, smart buildings, manufacturing, aerospace, military, petrochemical, oil wells, electricity, ships, and other medical pressure sensors.


Pressure sensor sales manufacturer


The pressure sensors produced by the pressure sensor sales manufacturer are one of the commonly used sensors in industrial practice. The output of conventional pressure sensors is an analog signal, which means that the information parameters are displayed as continuous signals within a specified range. Alternatively, during continuous time intervals, the characteristic quantity representing the information can be displayed as any number of signals at any time. The pressure sensors we commonly use are mainly made using the piezoelectric effect, and these sensors are also known as piezoelectric sensors.

We know that crystals are anisotropic, while amorphous materials are isotropic. Some crystalline media exhibit polarization effects when deformed by mechanical force in specific directions. Once the mechanical force is removed, they return to a non-electrical state. In other words, when subjected to pressure, some crystals generate electrical effects. This is the polarization effect. Scientists have developed pressure sensors based on this effect.

  Pressure sensor sales manufacturerThe pressure sensors produced mainly use piezoelectric materials such as quartz, potassium sodium tartrate, and diammonium phosphate. Among them, quartz (silicon dioxide) is a natural crystal where the piezoelectric effect was discovered. Within a certain temperature range, the piezoelectric material continues to exist, but if the temperature exceeds this range, the piezoelectric material will completely disappear (this high temperature is referred to as the "Curie point"). As stress changes, the change in the electric field is minimal (i.e., the piezoelectric coefficient is relatively low), and quartz is gradually replaced by other piezoelectric crystals. Potassium sodium tartrate can only be applied in environments with high piezoelectric sensitivity and piezoelectric coefficients, but low room temperature and humidity. Diammonium phosphate is an artificial crystal with a relative density of 1.80, a melting point of 190, and can withstand high temperatures and relatively high humidity, remaining stable in the air. At room temperature (20), its solubility in water is 37.4 grams, slightly soluble in ethanol, and has been widely used. Currently, the piezoelectric effect is also applicable to polycrystalline materials such as piezoelectric ceramics, including barium titanate piezoelectric ceramics, PZT, niobate piezoelectric ceramics, and niobium magnesium lead piezoelectric ceramics.

The piezoelectric effect is the main working principle of piezoelectric sensors, which cannot be used for static measurements. This is because the charge after external force will only be retained if there is infinite input impedance in the circuit. This is not the case in reality, so piezoelectric sensors can only measure dynamic stress.

Pressure sensors are mainly used for measuring acceleration, pressure, force, etc. Piezoelectric accelerometers are commonly used accelerometers. They have excellent characteristics such as simple structure, small size, light weight, and long lifespan. Piezoelectric accelerometers are widely used in measuring vibrations and impacts in aircraft, automobiles, ships, bridges, and buildings, especially in the aerospace field.
