IWATSU SY-8218\SY-8219 IWATSU Soft Magnetic AC B-H Core Loss POWER LOSS Analyzer

Model：SY-8219/SY-8218 Country of Origin：Japan

Category：B-H Analyzer

Overview：

For magnetic characteristics, flux density B (in T) and magnetic field strength H (in A/m) are plotted on the conventional X-Y axes, and the resulting curve is called the B-H curve. Methods for measuring the B-H curve include DC and AC evaluation methods. Our company currently offers a continuous AC measurement method for testing the B-H curve of magnetic materials under AC conditions. This capability has been well received by many users. Accordingly, today's AC B-H curve tracer is defined as a "B-H analyzer."

B-HFeatures of the SY-8218 Analyzer

Two cursors—a crosshair and a slanted cursor—display measured values and permeability at any point. In addition to the standard crosshair, the slanted cursor was optimized based on customer feedback specifically for measuring permeability at any point on the B-H curve, making testing more convenient.

1. Stable, high-precision measurement

With a standard calibration resistor, even materials with extremely low core loss, such as dust cores, can be measured stably and with high precision.

2. Captured waveform data at 8192 points per cycle

This product captures waveform data at 8192 points per cycle—16 times more than our previous models—enabling high-precision measurement of coercive force, residual magnetic flux density, and other parameters.

3. Pulse excitation included as standard

Pulse excitation (up to 1 MHz, 50% duty cycle) can be added to sine-wave excitation as standard equipment.

4. Parameter comparison setup

B-H curves of the same product measured under different conditions can be compared.
