CIT sensor, A split-core fluxgate current transducer, is specialised sensor used to measure the current flowing through a conductor in electrical engineering and power monitoring applications. It uses fluxgate technology principles to precisely measure and convert electrical current into a quantifiable output signal, making it a crucial component in a variety of industries and systems.

The “split-core” feature of CIT split core current transducer relates to its design, which allows the device’s core to be divided or opened, allowing it to be clamped around a live wire without having to disconnect the circuit. This design element offers comfort and ease of installation, making it appropriate for retrofitting into current systems as well as adding into new settings.

The operation of a split-core fluxgate current transducer is based on the manipulation of magnetic fields. The transducer’s core is comprised of a high magnetic permeability material and is coiled with exciting coils that generate an alternating magnetic field. This oscillating magnetic field causes changes in the magnetisation of the core, resulting in a variable magnetic flux within the core.

Sensorspoler placeret rundt om kernen registrerer ændringer i magnetisk flux og skaber et udgangssignal. Dette udgangssignal bliver derefter behandlet og forstærket for nøjagtigt at afbilde strømmen, der flyder gennem lederen.

Den ikke-påtrængende installation af en CIT split-core fluxgate strømtransducer er en af dens vigtigste fordele. Der er ingen grund til at afbryde kredsløbet ved blot at klemme enheden rundt om lederen, hvilket gør det til et muligt alternativ til overvågning af eksisterende systemer uden at generere nedetid.

Disse transducere bruges i en række forskellige applikationer, herunder strømdistribution, energistyring, industriel automation og andre. De er afgørende for at muliggøre effektiv energianvendelse, overvåge elektriske systemer og garantere sikker og pålidelig drift.
