Common types of resistive resistive sensor is to be measured, such as displacement, deformation, force, acceleration, humidity, temperature, etc. These quantities converted into a resistance value of formula such a device. There are resistance strain, piezoresistive, thermal resistance, thermal, gas, humidity and other resistive sensors. Frequency power inverter power sensor by voltage and current signals inputted AC sampling, and then enter the second instrument samples connected by transmission system with digital cable, optical fiber, digital input secondary instrument for voltage and current sample values calculates filter sensor supplier, you can get the voltage rms, current rms, fundamental voltage and fundamental current, voltage harmonics, harmonic current, active power, fundamental power, harmonic power and other parameters. Piezoresistive sensor device is based on the piezoresistive effect in a semiconductor material on a substrate of semiconductor material and made by a diffusion resistor. It can be directly used as a substrate to measure the sensing element filter sensor supply, the diffusion resistance in the substrate access into the form of a bridge. When the substrate is subjected to an external force and deforms the filter sensor production, each of the resistance value will vary, the bridge will have a corresponding unbalanced output. Silicon piezoresistive sensors used for piezoresistive sensor substrate (or membrane) main material for silicon and germanium, silicon sensitive material made of more and more people's attention, especially in measuring pressure and solid-state piezoresistive sensor applications speed the most common.
