B-H Analyzer
SY-8217
B-H curve measurement over 10 Hz to 5 MHz. The standard core loss measurement tool replaces V-A-W meters. The SY-8217 measures the magnetization characteristics of soft magnetic materials with high accuracy and in a short time over a wide frequency range from 10 Hz to 5 MHz. It is a powerful tool for research, development, manufacturing and inspection of low-loss magnetic materials for use in compact motor yokes, flyback transformers for TV, highfrequency power transformer, etc. Incorporating an oscillator for measurements and digitizer in a compact, desktop type cabinet, the SY-8217 is the ideal repalcement for an existing V-A-W(well known as a U-function) meter as the standard tool for core loss measurement.
SY-8217 10 Hz to 5 MHz
Wide measurement frequency bandwidth
Color TFT display The bright color TFT display shows the characteristic values, B-H curves and excitation waveforms simultaneously.
The frequency range for measurement ranges from 10 Hz to 5 MHz.
Printer and 3.5-inch FDD provided as standard
High-precision measurement An FFT arithmetic circuit permits automatic compensation and calibration of frequency characteristics of the measurement system.
The measurement results can be printed out immediately. Convenient for data sorting. The results can also be output to a 3.5-inch floppy disk in the csv format, then loaded in a PC and sorted using tabulation software.
High-speed measurement High-speed measurement can be performed in approx. 3 seconds, considerably improving measurement efficiency.
GP-IB interface provided as standard An automated measurement system can be constructed with a PC.
Compliance with JIS C2514, JIS H7153 and EMAS 5003. Ideal for estimation of everything from yoke materials for compact motors to the materials for high-frequency transformers. JIS C2514 : E-shaped ferrite core. JIS H7153 : High-frequency core loss test method for amorphous metallic cores. EMAS 5003 : Test method for ferrite cores of power applications. IEC 62044-3 : Cross-power method.
Compact, desktop size (Rack mountable)
Easy operation Simple and easy to use design.
