HYDAC pressure sensors are among the most commonly used sensors in industrial practice. They are widely used in various industrial automation environments, involving many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, power, shipbuilding, machine tools, and pipelines. Below is a brief introduction to the principles and applications of some commonly used sensors. Medical pressure sensors are also available. HYDAC Pressure Sensor Basic Introduction

[2] is one of the most commonly used sensors in industrial practice. The output of a typical pressure sensor is an analog signal, which refers to a signal whose 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 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 non-charged state. That is, under pressure, some crystals may produce an electrical effect, which is the so-called polarization effect. Scientists developed pressure sensors based on this effect.

The main piezoelectric materials 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field changes only slightly with stress (meaning the piezoelectric coefficient is relatively low), quartz has gradually been replaced by other piezoelectric crystals.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 generated after being subjected to external force is only preserved when the circuit has infinite input impedance. This is not the case in reality, which dictates that piezoelectric sensors can only measure dynamic stress.
