Fluxgate Current Sensor

The essence of the fluxgate principle is that the inductance of the easily saturated magnetic core changes with the magnitude of the excitation current under the action of the excitation current, and the change of the inductance leads to the change of the magnetic flux. The magnetic flux is opened or closed like a door, so it is visualized fluxgate Principle.

Accurate 32.768KHz Crystal for Metering Applications

Have you ever pondered the significance of the mystical number 32768? Well, it all boils down to the utilization of a 32768Hz, or 32.768kHz, frequency for RTC/Timer purposes, which yields a precise 1-second delay. Remarkably, 32768 is a power of 2—specifically, 2 to the power of 15 equals 32768. Consequently, employing a 15-stage divider, we can effectively divide 32.768kHz into 1Hz, laying the foundation for achieving a 1-second period with ease.

Multigap Ferrites for High Current Applications

The MultiGap concept is simple: instead of having one single large air gap in the center leg, the gap is distributed along the center leg by means of spacers along the leg length (up to seven smaller gaps). Reduce significantly the fringing Flux around them, allowing the coil to be much closer to the center leg and keeping the eddy current losses in the winding very low.
