笔者曾在本刊1996年第12期上发表的“新型微功耗磁传感探测器”一文中,介绍了该探测器的基本原理、电路构成和应用前景。本文作为上述文章的补充,较详细地阐述新型微功耗磁传感探测器所用的关键部件——新型微功耗磁传感器在不同应用场合要考虑和解决的实际技术问题。 现已能提供用户选用的新型微功耗磁传感器有φ43×19毫米和φ36×19毫米两种规格。传感器有一根三芯电缆相连,其中一根芯线和屏蔽线作为电源输入线,其余两根芯线为传感器的信号输出线。传感器由6伏稳压电源供电,红色芯线接电源正极,屏蔽层编织线接电源负极。两根信号输出端线可组成平衡方式输出,也可以接成非平衡方式输出。传感器只要接上电源,就能正常工作,用电压表或电平记录仪作为终端显示装置就能得到代表传感器所在地点存在的磁场
The author has published in the 12th issue in 1996, “a new micro-power magnetic sensor detector,” a paper, describes the basic principles of the detector, circuit configuration and application prospects. As a supplement to the above article, this paper elaborates the key components used in the new micro-power magnetic sensor detector in detail - the actual technical problems that the new micro-power magnetic sensor should consider and solve in different applications. Now available to users of the new micro-power magnetic sensor has φ43 × 19 mm and φ36 × 19 mm two specifications. The sensor has a three-core cable connected to one of the core and shielded wire as the power input line, the remaining two wires for the sensor signal output line. The sensor is powered by a 6-volt regulated power supply, the red wire is connected to the positive terminal of the power supply, and the shielding braid is connected to the negative terminal of the power supply. Two signal output terminal line can be composed of balanced output, can also be connected as unbalanced output. As long as the sensor connected to the power supply, you can work properly, with a voltmeter or level recorder as a terminal display device can be representative of the location of the sensor where the magnetic field
