Voltage Sensor

SmartQ Voltage Sensor ±12V

The Smart Q Voltage sensors are used to measure the potential difference between the ends of an electrical component. This range of Voltage sensors can be used to measure both DC and low-voltage AC circuits.

This ±12V Voltage sensor can be used to monitor voltage over a fast short or long slow period of time in addition to spot measurements.
