    Tips: Measuring requirements when using voltage sensors

    To measure the voltage with a voltage sensor, it is generally required that the collected voltage signal is proportional to the measured voltage in amplitude, and the phase angles of the two are exactly the same or the difference is extremely small. In addition, there are the following basic requirements for the voltage sensor.

    1. The connection of the voltage sensor to the circuit under test should basically not affect the amplitude and waveform of the voltage under test.
    2. The voltage waveform obtained by the voltage sensor should be the same as the measured voltage waveform, and the voltage divider ratio should be independent of the measured voltage frequency and amplitude.
    3. The voltage divider ratio has nothing or basically nothing to do with atmospheric conditions (air pressure, temperature and humidity).
    4. The power consumed by the voltage sensor should not be large. Under certain cooling conditions, the temperature rise formed by the electrical energy dissipated by the voltage divider should not cause a change in the voltage divider ratio.
    5. The voltage sensor should not be interfered by the external electromagnetic field, and on the other hand, it should not produce strong electromagnetic interference from the external environment.

    I want to buy your voltage sensor
    I have come up with your product below:
    Voltage Sensor
    Though, I have 2 questions:
    1) I see there are several inputs for Voltage from 0V – 1000V. My first question is how can I select a range of fe150V?
    In such case, what will the accuracy at low voltages fe 4V (I need accuracy of 2 decimals)?
    Is there an option to switch between 2 ranges in one single sensor?
    2) If I adjust the output range to 0-10V (this is my acceptable PLC input), what will be the output in case of reverse polarity connection? I really want to avoid a negative signal on my PLC input.

    1. Select required measuring range as you like from the pull down menu seen on the web site, and accuracy is: 0.2%F.S.
      No option is to switch between 2 ranges in one single sensor.
    2. This is a DC voltage sensor, so the input voltage cannot reverse polarity connection, otherwise it may cause damage to the sensor.
