产品详情

  TKC-DHR420系列高精度真有效值霍尔电流变送器的初、次级之间是绝缘的,无位置误差,用于精密测量直流、交流和脉动电流。

  TKC-DHR420 series current sensor is a true RMS device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit, the size of primary doesn’t affect test precision, no matter the location of primary in the hole of current sensor, it uses for precision measurement of DC, AC and pulse current.

  Remarks:

  1. All dimensions are in mm.

  2. General tolerance ±1mm.

  使用说明 Directions for use

  1. 当待测电流从传感器穿过,即可在输出端测得电压大小。(注意:错误的接线可能导致传感器损坏)

  When the current will be measured goes through a sensor, the voltage will be measured at the output end. (Note: The false wiring may result in the damage of the sensor)

  2. 传感器的输出幅度可根据用户需要进行适当调节。

  Customs can adjust output amplitude of the sensor by needs.

  3. 可按用户需求定制不同额定输入电流和输出电压的传感器。

  Custom design in the different rated input current and the output voltage are available.
