Current Sensor
Reveals electrical load, stress, and hidden mechanical issues through current consumption.
What Does a Current Sensor Measure?
A current sensor measures the amount of electrical current flowing through a conductor. In industrial systems, current directly reflects load, torque demand, and overall health of motors, heaters, compressors, pumps, and electrical equipment.
Signal Output
- Analog: 4–20 mA
- Analog: 0–10 V
- Digital: RS485 / Modbus
- Derived values: RMS current, phase current, imbalance
What Does the Signal Mean?
| Current Behaviour | Industrial Meaning |
|---|---|
| Stable rated current | Normal electrical and mechanical operation |
| Gradual current increase | Overloading, bearing wear, or process resistance |
| Sudden current spike | Mechanical jam, short circuit, or insulation issue |
| Phase current imbalance | Supply issues, winding damage, or uneven load |
