Basic Introduction to HYDAC Sensors

[2] is one of the most commonly used sensors in industrial practice. Generally, the output of ordinary pressure sensors is an analog signal. An analog signal is a signal in which the information parameters are continuous within a given range. Or, within a continuous time interval, the characteristic quantity representing the information can be presented as an arbitrary value at any instant. The pressure sensors we usually use are mainly made using the piezoelectric effect. Such sensors are also called piezoelectric sensors.

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

The piezoelectric materials mainly used in piezoelectric 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 disappears 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field changes only slightly with stress (meaning the piezoelectric coefficient is relatively low), quartz has gradually been replaced by other piezoelectric crystals.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.

Piezoelectric sensors are mainly used in the measurement of acceleration, pressure, and force. A piezoelectric accelerometer is a commonly used accelerometer. It has 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, and hold a special place in the aerospace field. 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. It 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 widespread application.

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.

HYDAC sensors are characterized by miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They not only promote the transformation and upgrading of traditional industries but also have the potential to establish new industries, thus becoming a new economic growth point in the 21st century. Miniaturization is based on Microelectromechanical Systems (MEMS) technology and has been successfully applied to silicon devices to create silicon pressure sensors.

The HYDAC sensor project is a general term for sensors designed to replace contact detection methods such as limit switches, aiming to perform detection without contact with the object being detected.

The HYDAC sensor project is a very important member of the sensor family and has wide-ranging industrial applications. Although the price of a single proximity sensor is not very high, factories typically require them in bulk, resulting in a large market for proximity sensors. When it comes to proximity sensors, well-known brands like Turck, Omron, and Balluff are widely recognized; these brands have dominated the proximity sensor market for a considerable period.

HYDAC sensors are among the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries.
