Electronic devices called PCB-mount current transducers, often referred to as current sensors or current transformers, are made to measure electric current in a variety of applications.
They are useful for integration into small electronic devices since they are created specifically to be put directly onto printed circuit boards (PCBs).
These transducers measure current using the electromagnetic induction concept.
They are made up of a secondary winding and a conductor known as the primary winding, which normally carries the current being measured.
While the secondary winding is linked to a load or measurement circuit, the primary winding is routed through or around the current-carrying conductor.
A magnetic field is produced when primary winding current flows, and this magnetic field causes a proportionate voltage to be induced in the secondary winding.
A signal that indicates the current being monitored can be produced by measuring this voltage.
To give a useable output, PCB-mount current transducers may include extra circuitry, such as amplifiers or signal conditioning.
Depending on the requirements of the particular application, these transducers may have multiple output kinds, such as voltage output, current output, or digital output.
The output signal can be customised to the required range or frequency response using features like adjustable gain or filtering options that some models may also have.
It is crucial to take into account aspects like the maximum current range, accuracy requirements, voltage or current output levels, bandwidth, and power supply compatibility when choosing a PCB-mount current transducer.
To guarantee correct installation and usage, it is also crucial to review the manufacturer’s datasheet and application guidelines.
With their consistent performance and simplicity of integration on printed circuit boards, PCB-mount current transducers offer a practical and precise option for measuring and monitoring electrical currents in a variety of electronic systems and applications.
The global PCB-mount current transducers market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A new transducer series from LEM is perfect for trackside applications that need to be retrofitted and for cutting the price of new installations.
For isolated dc, ac, and pulsed current measurement of nominal currents from 100A to 200A, LEM has announced a line of PCB-mount transducer
