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
