产品详情

  TBV-A25系列电压传感器的初、次级之间是绝缘的,可用于测量直流、交流和脉冲电压。

  TBV-A25 series current mode voltage sensor is a closed loop device based on the principle of the hall effect and null balance method. The output from the voltage sensor can be expressed as a voltage by passing it through a resister. Input voltage can be expressed as a current by passing it through a input resister. It provides accurate electronic measurement of DC AC or pulse and pulsed voltage.

  Remarks:

  1. All dimensions are in mm.

  2. General tolerance ±1mm.

  使用说明 Directions for use

  1. 当待测电压从变送器输入端输入,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 voltage will be measured goes through a transmitter, the voltage will be measured at the output end.

  (Note: The false wiring may result in the damage of the senor).

  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压和输出电压的传感器。

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