HYDAC Pressure Sensor Basic Introduction

HYDAC pressure sensors are among the most commonly used sensors in industrial practice. Ordinary pressure sensors typically output analog signals, which are signals whose information parameters are continuous within a given range. Alternatively, within a continuous time interval, the characteristic quantity representing the information can exhibit any value at any instant. The pressure sensors we commonly use are mainly manufactured using the piezoelectric effect; such sensors are also called piezoelectric sensors.

We know that crystals are anisotropic, while amorphous materials are isotropic. Some crystalline media, when deformed by mechanical force along a certain direction, produce a polarization effect; when the mechanical force is removed, they return to a neutral state. That is, under pressure, some crystals may produce an electrical effect; this is the so-called polarization effect. Scientists have developed pressure sensors based on this effect.

The main piezoelectric materials used in HYDAC pressure sensors include quartz, sodium potassium tartrate, and ammonium dihydrogen phosphate. Quartz (silicon dioxide) is a natural crystal, and the piezoelectric effect was discovered in it. Within a certain temperature range, the piezoelectric property persists, but it is lost above this range (this high temperature is known as the "Curie point"). Because the electric field changes only slightly with stress (meaning the piezoelectric coefficient is relatively low), quartz has gradually been replaced by other piezoelectric crystals. Sodium potassium tartrate has a high piezoelectric sensitivity and coefficient, but it can only be used in environments with low room temperature and low humidity. Ammonium dihydrogen phosphate is a synthetic crystal with a relative density of 1.80 and a melting point of 190℃. It can withstand high temperatures and relatively high humidity and is stable in air. At room temperature (20℃), its solubility in water is 37.4g, it is slightly soluble in ethanol, and insoluble in acetone, thus it has been widely used. The piezoelectric effect is also now applied to polycrystalline materials, such as piezoelectric ceramics, including barium titanate piezoelectric ceramics, PZT, niobate-based piezoelectric ceramics, lead magnesium niobate piezoelectric ceramics, etc.

The piezoelectric effect is the main working principle of piezoelectric sensors. Piezoelectric sensors cannot be used for static measurements because the charge after being subjected to external force is only preserved when the circuit has infinite input impedance. This is not the case in reality, which determines that piezoelectric sensors can only measure dynamic stress.

HYDAC pressure sensors are mainly used in the measurement of acceleration, pressure, and force. Piezoelectric accelerometers are a commonly used type of accelerometer. They have excellent characteristics such as simple structure, small size, light weight, and long service life. Piezoelectric accelerometers have been widely used in vibration and shock measurements in aircraft, automobiles, ships, bridges, and buildings, especially in the aerospace field where they hold a special place. Piezoelectric sensors can also be used to measure the internal combustion pressure of engines and vacuum levels. They can also be used in the military industry, for example, to measure the change in chamber pressure at the moment of firing and the shock wave pressure at the muzzle. They can be used to measure both large and small pressures. Piezoelectric sensors are also widely used in biomedical measurements. For example, ventricular catheter microphones are made using piezoelectric sensors because measuring dynamic pressure is so common, leading to their wide range of applications.

Besides piezoelectric sensors, there are also piezoresistive sensors (utilizing the piezoresistive effect) and strain gauge sensors (utilizing the strain effect). These different pressure sensors utilize different effects and materials, and can be used in various applications.
