特斯拉计

Tesla meter

高斯计（又称特斯拉计）是根据霍尔效应原理制成的测量磁感应强度的仪器，它由霍尔探头和测量仪表构成。霍尔探头在磁场中因霍尔效应而产生霍尔电压，测出霍尔电压后根据霍尔电压公式和已知的霍尔系数可确定磁感应强度的大小。高斯计的读数以高斯或千高斯为单位。是用于测量和显示单位面积平均磁通密度或磁感应强度的精密仪器。测量物体于空间上一个点的静态或动态（交流）磁感应强度， 由霍尔传感器（精度更高可选择磁通门传感器）.经过物体磁力线穿过产生电流电压，主设备上面显示磁感应强度。

Gauss meter (also called Tesla meter) is an instrument for measuring magnetic induction intensity based on Hall effect principle. It consists of Hall probe and measuring instrument. Hall probe generates Hall voltage due to Hall effect in magnetic field. After Hall voltage is measured, the magnitude of magnetic induction intensity can be determined according to Hall voltage formula and known Hall coefficient. Gaussmeter readings are in gauss or thousands of gauss. It is a precision instrument for measuring and displaying the average magnetic flux density or magnetic induction intensity per unit area. The static or dynamic (alternating current) magnetic induction intensity of an object at a point in space is measured by a Hall sensor (a fluxgate sensor with higher precision is selected). Current and voltage are generated by passing through magnetic lines of force of the object, and the magnetic induction intensity is displayed on the main equipment.

高斯计需要能够测量恒定磁场,直流磁场与交流磁场和脉冲磁场的功能。 同时由于智能制造发展高斯计需要能够与自动化设备有交互功能，因而485通讯与开关量端口,模拟信号端口成为必须。

Gauss meter needs to be able to measure constant magnetic field, DC magnetic field, AC magnetic field and pulse magnetic field. At the same time, due to the development of intelligent manufacturing, gauss meter needs to be able to interact with automation equipment, so 485 communication, switching value port and analog signal port become necessary.

现如今市场高斯计随着设计技术进步，已经由原有的模拟电路转化成STC单片机设计的方案，近年来随着高斯计功能增强，内部程序的复杂程度也提高了。

Nowadays, with the development of design technology, the Gauss meter in the market has been transformed from the original analog circuit to the STC microcontroller design scheme. In recent years, with the enhancement of the function of the Gauss meter, the complexity of the internal program has also increased.
