dc电流探头原理
DC电流探头的工作原理主要基于霍尔效应。

当电流经过一根导线时，会在导线周围产生磁场。

霍尔器件能够感应到这个磁场，并输出相应的电压信号。

通过测量这个电压信号，可以推算出流过导线的电流大小和方向。

在DC电流探头中，被测量的直流电流通过一个导磁材料（例如坡莫合金）传递到一个霍尔器件上。

霍尔器件能够将磁场变化转化为电信号，从而反映出被测电流的大小和方向。

为了消除误差和提高测量精度，DC电流探头通常会采用一系列的校准和补偿措施，例如温度补偿、零点校准等。

此外，DC电流探头通常还需要与一个测量仪表或示波器配合使用，以便将电信号转化为易于观察和测量的形式。

不同类型的DC电流探头具有不同的规格和适用范围，例如量程、精度、频率响应等。

选择合适的DC电流探头需要根据实际需求和应用场景来决定。

N2780A Series AC/DC Current ProbesA wide selection of current probes to meet your application's needsData Sheet• Various bandwidths: DC to 2 MHz, 10 MHz, 50 MHz, 100 MHz• DC and AC measurements• Superior 1% accuracy and high signal-to-noise ratio• Overload-protect function prevents probe damage from excessive input • Direct connection to high-impedance 1 MΩBNC input of oscilloscope • “Demagnetize” button to remove any residual magnetism that builds up in the magnetic core• External power supply (N2779A) lets you connect up to three N278xA current probes to a single power supplyCompatible with any oscilloscope with a high-impedance BNC input, the new N2780A Series current probes offer accurate and reliable solution for measuringDC and AC currents. Hybrid technology for AC and DC measurementsUsing hybrid technology that includes a Hall-effect sensor and an AC current transformer, the probes provide accurate measurement of DC or AC currents up to 500 Arms (for model N2780A) or DC–100 MHz (for model N2783A), without breaking into the circuit. Using split core construction, the probe easily clips on and off of a conductor.Wide range of applicationsThe current probes feature broad measurement ranges (up to 500 A), flat frequency response, low noise and low insertion loss that make the probes ideal for current measurements in areas such as measuring steady state or transient current of motor drives, switching power sup-plies, inverters, controllers, sensors, disk drives, LCD displays, elec-tronic ballasts and amplifiers. The high signal-to-noise ratio of theN2782A and N2783A makes them ideal for making low-level current measurements in milliampere ranges.Accurate current measurementA built-in DEMAG (demagnetize) function allows the removal of any residual magnetism that has built up in the magnetic core due to power on/off switching or excessive input current. In addition, voltage offset or temperature drift on the probe can be easily corrected by using thezero adjustment control.Figure 1 N2780A Series current probeswith N2779A power supplyFigure 2 N2783A, N2780A, N2781A and N2782A current probe (from left to right)2Figure 3 Frequency response of N2783AFigure 4 Continuous maximum input rating of N2783ACompatible OscilloscopesAny oscilloscope offering 1 MΩBNC input including Agilent 3000Series, 6000 Series, and Infiniium8000 Series oscilloscopes.

When connected to Tektronix oscilloscopes with TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC)interfaces, current measurements and calculations are simple and easy.Key performance specificationsDC - 100 MHz, Current Probe Amplifier (TCPA300) uses:DC - 100 MHz, 30 A DC (TCP312A)DC - 50 MHz, 50 A DC (TCP305A)DC - 15 MHz, 150 A DC (TCP303)DC - 50 MHz, Current Probe Amplifier (TCPA400) Uses:DC - 2 MHz, 750 A DC 1 (TCP404XL) (500 A DC Continuous)1Derated with duty cycleKey featuresAutomatic scaling and units 2 - Oscilloscope on-screen readout of magnitude and amps reduces measurement errors with no more hand calculations AC/DC input couplingLow insertion impedance reduces device under test loading Split-core construction allows easy circuit connectionStatus indicators provide visual operating status and notification of potential error conditions - degauss, probe open, overload, not terminated into 50 Ω, noncompatible probe typeLow DC drift and noise allows improved low-level current measurements3rd party safety certification2 Requires a TDS TEKSCOPE oscilloscope or a TekConect oscilloscopewith TCA-BNC adapterApplicationsDevelopment and analysis solutions for designers, installers, and service personnel in telecom, data comm, computer, and semiconductor power electronics environments for:Power supplies (switching and linear)Semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs)Power inverters/converters Electronic ballastsIndustrial/consumer electronicsMobile communications (phone, satellite, relay stations)Motor drivesTransportation systems (electronic vehicles, electric trains, locomotives,avionics)Meets today's AC/DC current measurement applicationsThe TCPA300 amplifier, when used with TCP312A, TCP305A, or TCP303probes, provides a wide range of current measurement capability and spans the gap between low-level milliamp measurements to very high current levels. These three probes provide current measurement capabilities of 30 A, 50 A, and 150 A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500 A DC continuous and 750 A DC continuous, derated with duty cycle.Higher-frequency performance is available with the TCP312A w/TCPA300providing ≥100 MHz bandwidth and a maximum current of 30 A DC.Measurement errors and manual calculations are now a thing of the pastWith this new series of current measurement tools, automatic control and on-screen scaling and units is provided for users of Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000, and TDS7000B series oscilloscope systems (the DPO3000, MDO/MSO/DPO4000, MSO/DPO5000, and DPO7000 series oscilloscopes, the TPA-BNC adapter is required).The TCP300/TCP400 current measurement systems seamlessly integrate with your TDS series oscilloscope.Even non-TEKPROBE systems can use the TCPA300/400 series to make proper current measurements by simply multiplying the measured output voltage on the oscilloscope by the TCPA300/400 series range setting.SpecificationsAll specifications apply to all models unless noted otherwise.

探头可以提供一个低电压（i3000s 型为 3 V 交流电，i2000 为 2 V 交流电）输出，该输出与被测电流成正比。

使用 i3000s 型时，探头可提供 30 A、300 A 和 3000 A 满刻度直接读数；若使用 i2000 则为 20 A、200 A 和 2000 A。

小心一词代表对校准器或测试仪器可能造成损坏的情况或行为。

WX警告为了避免触电或人身伤害：•探头只能由具备资格的人士使用。

•在安装和使用探头时要小心；被测电路上可能带有高压和电流。

•探头只能由合格的维修人员负责进行维护。

•防止探头受潮和进水。

•视需要穿戴防护服和手套。

•不要将本产品安装在带电导体上。

在安装柔性测量头之前，始终记住断开被测电路的电源。

•在使用探头之前，总是先检查电子装置、连接电缆及柔性测量头是否损坏。

L2000-C射频导纳物位控制器说明书一、概述山东中煤工矿物资集团有限公司（原济宁中煤机械制造厂）生产的L2000-C系列射频导纳物位开关是一种新颖的物位测量仪表，它采用先进（抗粘附）射频导纳技术，克服了电容式物位计不能消除导电挂料影响的缺陷，仪表具有运行可靠，能抗挂料层的影响。

L2000-C标准探头中心信号杆采用直径10mm不锈钢，保护套长150mm，总长450mm，坚固实用。

有L890C平板探头，解决大固体物料冲击棒的问题。

有L863WC钢缆探头，使L2000C适用于几乎所有工业现场对液体；粉料；块料；高温场合的物位检测。

仪表还具有安装方便，免维护，价格低等特点。

仪表广泛用于石油、化工、冶金、医药、电力、食品、造纸等工业领域。

二、参数特点：开关控制，射频导纳原理，NULL-KOTE抗粘附电子线路。

继电器容量：DPDT，额定10A，115V/AC延时/模式：0~30秒可调/开关型电源：230Vac，3瓦或24V/DC<3瓦灵敏度：小于0.5Pf探头耐温：40℃～+80℃(可定制高温探头800C°)电路部份耐温；-40℃～+80℃失电保护（Fail—Safe）模式：采用高低模式，现场可调外壳：IP65，重型铸铝外壳三、选型指南1）在测非导电介质时，可以为水平或垂直安装，如需要垂直安装时，要求探头长至少大于控制位置6英寸左右。

2）在测导电液体时、泥浆或界面检测时，可以水平垂直安装，但探头穿过容器壁时，保护电极应比容器壁上的积料厚度长出2英寸。

如用户需要，我们可以提供液介质为Teflon或Kyanr材料的防腐探头（采用涂层法兰连接）。

校准1）灵敏度的校正当进行调节时，请注意这些总的规则：*将2个灵敏度调节电位器逆时针旋转增加灵敏度。

*当两个灵敏度控制调好后，红色灯亮，表示探头上“有”物料存在，绿色灯亮，表示（无）物料存在。

*安装方法有水平或垂直两种。

为保证设备稳定工作应有5分钟预热。
