霍尔效应传感器是一种检测磁场的磁敏传感器,已经被广泛地用来构成检测附近金属的接近传感器,构成无电刷电动机等等。而且,在计测领域也得到了广泛使用,例如利用霍尔效应传感器原理和霍尔效应传感器制成磁场场强计;利用霍尔效应传感器的独特的乘法特性制作功率表等等。本文将向广大读者,先介绍霍尔效应传感器的使用方法,然后介绍如何使用霍尔效应传感器与CT(电流变换器)组合而成的霍尔效应CT来制作一台功率表。
Hall-effect sensor is a magnetic field sensor to detect magnetic sensors, has been widely used to detect the proximity of the metal sensor to form a brushless motor and so on. In addition, the field of measurement has also been widely used, for example, the use of Hall-effect sensor principle and the Hall effect sensor made of magnetic field strength meter; the use of Hall effect sensor unique multiplication characteristics of the power meter and so on. This article will introduce the use of Hall effect sensors to readers, and then introduce how to make a power meter using a Hall effect CT combined with Hall effect sensors and CT (Current Transducer).
