Working principle of pressure sensor:
1. Piezoresistive force sensor: Resistance strain gauges are one of the main components of piezoresistive strain sensors. The working principle of metal resistance strain gauges is the phenomenon where the strain resistance changes with mechanical deformation due to adsorption on the substrate material, commonly known as the resistance strain effect.
2. Ceramic pressure sensor: Ceramic pressure sensors are based on the piezoresistive effect, where pressure directly acts on the front surface of the ceramic diaphragm, causing slight deformation of the diaphragm. Thick film resistors are printed on the back of the ceramic diaphragm and connected to form a Wheatstone bridge. Due to the piezoresistive effect of the varistor, the bridge generates a highly linear voltage signal proportional to the pressure and the excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3 mV/V depending on the pressure range, and can be compatible with strain sensors.
3. Diffusion silicon pressure sensor: The working principle of diffusion silicon pressure sensor is also based on the piezoresistive effect. Using the principle of piezoresistive effect, the pressure of the measured medium directly acts on the diaphragm of the sensor (stainless steel or ceramic), causing the diaphragm to produce a micro displacement proportional to the medium pressure, which changes the resistance value of the sensor. The electronic circuit detects this change and converts it into a standard measurement signal corresponding to this pressure.
4. Sapphire pressure sensor: utilizing the principle of strain resistance, using silicon sapphire as the semiconductor sensitive element, it has metrological characteristics. Therefore, semiconductor sensitive components made of silicon sapphire are insensitive to temperature changes and have good working characteristics even under high temperature conditions; The radiation resistance of sapphire *; In addition, silicon sapphire semiconductor sensitive components have no p-n drift.
5. Piezoelectric pressure sensor: The piezoelectric effect is the main working principle of piezoelectric sensors. Piezoelectric sensors cannot be used for static measurement because the charge after external force is applied is only saved when the circuit has an infinite input impedance. The actual situation is not like this, so this determines that piezoelectric sensors can only measure dynamic stress.
Pressure sensors are the most commonly used sensors in industrial practice, widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, power, ships, machine tools, pipelines and many other industries. And different types of pressure sensors need to be used in different environments to avoid errors.
