    Tips: Wireless pressure sensor working principle

    Wireless pressure sensors are the most commonly used sensors in industrial practice, which are used in hydrological monitoring and control systems, petrochemical, environmental protection, water pipe network monitoring, reservoir level monitoring, power station operation inspection, locomotive braking systems, industrial process detection and control, laboratory liquid level calibration, etc.

    The wireless pressure sensor adopts the piezoresistive strain principle. Its core component, the resistance strain gauge, is a sensitive device that converts the strain change on the measured object into an electrical signal. It is one of the main components of the sensor. The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. There are two types of metal resistance strain gauges: filamentary strain gauges and metal foil strain gauges. Usually, the strain gauge is tightly bonded to the matrix that generates mechanical strain through a special adhesive. When the stress of the matrix changes, the resistance strain gauge is also deformed together, so that the resistance value of the strain gauge changes, so that the voltage applied to the resistor changes. The resistance change of this kind of strain gauge is usually small when it is stressed. Generally, this kind of strain gauge constitutes a strain bridge, so that the change of impedance is converted into a digital signal.
