5 Types of Pressure Sensors

Piezoelectric pressure sensor:

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, it can only be saved when the loop has infinite input impedance. This is not the case, so this determines that piezoelectric sensors can only measure dynamic stress.

Ceramic pressure sensor:

Ceramic pressure sensors are based on the piezoresistive effect. Pressure directly acts on the front surface of the ceramic diaphragm, causing the membrane to deform slightly. Thick film resistors are printed on the back of the ceramic diaphragm and connected into a Wheatstone bridge. Because of the varistor The piezoresistive effect makes the bridge generate a voltage signal that is highly linear and proportional to the pressure and proportional to the excitation voltage. The standard signal is calibrated to 2.0 / 3.0 / 3.3mv / v according to different pressure ranges. Strain sensors are compatible.

Diffused silicon pressure sensor:

The working principle of a diffused silicon pressure sensor is also based on the piezoresistive effect. Using the piezoresistive effect principle, the pressure of the measured medium directly acts on the diaphragm of the sensor (stainless steel or ceramic). The diaphragm produces a micro-displacement proportional to the pressure of the medium. Change the resistance value of the sensor. Use electronic circuits to detect this change, and convert and output a standard measurement signal corresponding to this pressure.

Sapphire pressure sensor:

Utilizing strain-resistance working principle. Using silicon-sapphire as the semiconductor sensitive element has unparalleled metrological characteristics. Therefore, silicon-sapphire semiconductor sensitive components are used. They are not sensitive to temperature changes and have good working characteristics even under high temperature conditions. Sapphire has extremely strong radiation resistance. In addition, silicon-sapphire semiconductor sensitive components, pn drift.

Piezoresistive force sensor:

Resistance strain gage is one of the main components of a piezoresistive strain sensor. The working principle of a metal resistance strain gage is that the resistance of the strain resistance absorbed by the base material changes with the mechanical deformation.
