Model：SY-8219,SY-8218 Country of Origin：Japan
Category：B-H Analyzer
The global industry standard for soft magnetic AC loss evaluation, an IEC-62044-3 standardized instrument product, manufactured in Japan by Iwasaki Communication Equipment. Since its launch in 1988, it has led the trend of the soft magnetic materials industry and is the most trusted professional instrument of numerous research institutions, universities, and enterprises.
BHFeatures of the SY-8218 Analyzer |
1. Stable, high-precision measurement With standard calibration resistors, even materials with extremely low core loss, such as dust cores, can be measured stably and with high precision. 2. Captured waveform data: this product captures waveform data at 8192 points per cycle, 16 times more than our previous models, enabling high-precision measurement of coercivity and residual magnetic flux density. 3. Pulse excitation included as standard Pulse excitation (up to 1 MHz, 50% duty cycle) can be added to sine-wave excitation as a standard feature. 4. Parameter comparison setup B-H curves of the same product under different measurement conditions can be compared. 5. Two cursor types Display measured values at any point, with permeability measured using two cursor types: a standard crosshair and a slanted cursor. The standard crosshair plus "slanted cursor" allows permeability measurement at any point on the B-H curve. This feature was optimized based on customer feedback to simplify testing. |
