Tips: What is the working principle of Hall effect voltage sensor?
The Hall effect voltage sensor uses Hall effect to pass the primary voltage through an external or built-in resistor to limit the current to 10mA. After this current passes through multiple turns of winding, the magnetic field, which is generated through a magnetic material, will be detected by the Hall element in the air gap, and the corresponding electromotive force is induced. The electromotive force is adjusted by the circuit and fed back to the compensation coil to compensate. The magnetic flux generated by the compensation coil and the primary current (The measured voltage is generated by current limiting resistor.) the generated magnetic flux is equal in magnitude and opposite in direction, thus keeping the magnetic flux in the magnetic core to be zero. In fact, the Hall voltage sensor uses the same technology as the magnetic balance closed-loop Hall effect current sensor, that is, the zero flux Hall current sensor.

I thought of your voltage sensor

I have come up with your product below:
Voltage Sensor
ATO-VOS-DC1000
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.
