ABB CT系列传感器

• High linearity
• Large dynamic range
• Non-saturable
• ***all dimensi***, light weight
• Only few types for whole product range
• Simplified engineering and logistics

The current sensor is based on the principle of Rogowski-coil. The sensor c***ists of an air-core winding, immune of any risk of saturation as it has no ferromagnetic core. It is linear over the whole measuring range. The output signal is a voltage, which is proportional to the derivative of the current. A digital integration of this voltage is carried out and gives the measured current.
