Technical Specifications

Function and Working Principle

The Bently Nevada 163947-00-05-02-84-90 Non-Contact Current Sensor operates based on the principle of inductive coupling, allowing it to measure electrical current without physical contact with the conductor. Here’s how it functions:

• Inductive Measurement: The sensor detects the magnetic field generated by the current flowing through a conductor. The non-contact design means it can measure the current without having to physically touch the conductor, thus providing enhanced safety.
• Magnetic Field Detection: The current passing through a conductor generates a magnetic field. The sensor detects this magnetic field and converts it into a proportional electrical signal, which is then processed for accurate measurement and analysis.
• High Precision: Designed for precision, the sensor ensures that even small changes in current are detected and measured, making it ideal for monitoring critical systems where precise current control is essential.
• Safe Monitoring: Because there is no need for direct contact with the electrical circuit, this sensor minimizes the risk of electrical hazards, making it a safer option for maintenance and monitoring of high-voltage systems.
