Vision sensor means: having the ability to capture the entire image from a number of light made thousands of pixels, high-quality filters, sensors, image clarity and detail of the resolution used to measure, filter sensors offer, represents a number of pixels . Vision sensor has captured light from a whole image of thousands of pixels. Image clarity and detail of the resolution is usually measured by the number of pixels represented. After capturing an image, vision sensors to compare it with the reference image stored in memory to make the analysis. For example, if the vision sensor is set to identify correctly inserted eight bolts of machine parts, the sensor should be rejected member knows only seven bolts or screws misaligned parts. In addition, the filter sensor manufacturers, regardless of the field of view of the machine parts which position, Wenzhou filter sensor, regardless of whether the member is in the range of 360-degree rotation, the visual sensor can judge. Common types of resistive resistive sensor is to be measured, such as displacement, deformation, force, acceleration, humidity, temperature and other physical quantities converted into a resistance value of formula such a device. There are resistance strain gauge, piezoresistive, thermal resistance, thermal, gas, humidity and other resistive sensors. Frequency power inverter power sensor through the voltage and current signals inputted AC sampling, then sampling values ??entered secondary instrument connected via a transmission system, with digital cable, optical fiber, digital input secondary instrument for voltage and current sample values for computing, you can get the voltage rms, current rms, fundamental voltage and fundamental current harmonic voltage and harmonic current, active power, fundamental power, harmonic power and other parameters.
