Voltage Sensor
Monitors electrical supply quality to protect industrial equipment and processes.
What Does a Voltage Sensor Measure?
A voltage sensor measures the electrical potential difference between conductors. In industrial environments, voltage stability is critical for safe, efficient, and reliable operation of motors, drives, control panels, and automation systems.
Signal Output
- Analog: 4–20 mA
- Analog: 0–10 V
- Digital: RS485 / Modbus
- Derived values: Phase voltage, line voltage, voltage imbalance
What Does the Signal Mean?
| Voltage Behaviour | Industrial Meaning |
|---|---|
| Rated stable voltage | Healthy power supply and equipment operation |
| Under-voltage | Overcurrent risk, motor overheating, torque loss |
| Over-voltage | Insulation stress, drive damage, reduced equipment life |
| Voltage imbalance | Uneven phase loading, winding damage, vibration increase |
