TYU-2000A AC Hysteresisgraph of Loudi Tianyu Electronic was developed successfully by Hunan Loudi Tianyu Electronic Co.,LTD separately and it is the new type measuring device with independent intellectual property right. This device adopt digital signal processing synthesis, gathering Collection Technology, successful development of standard signal source, Standard Power Meter, Peak Voltmeter, Mean Voltmeter as a whole integrated measuring and controlling unit. It realizes high precision and all parameters measuring by Combining with the power amplifier unit which have wide frequency, large power.
Functional Features
It has reached the international advanced level on power outputting, magnitude tracing and accuracy measuring and so on.
The design and manufacture of TYU-2000A Type Soft Magnetic Alternating Current Auto-testing Equipment completely meets the national standards GB3658-83 GB9632-88, international standard IEC367-1 and the national measurement verification standard JJG493-87. It can measure the dynamic magnetic characteristics of all kinds of metal soft magnetic material(Such as permalloy、ferrite material and so on). The main measurement parameters including Total Loss Ratio Ps、Incremental Permeability μm、inductance magnetic permeability μL、elastic magnetic permeability μ′、viscous magnetic permeability μ″ and Q value and so on. Voltammetry method that starting from the definition to measure the losses Ps and the incremental permeability μm is mainly used by the measurement of this device, meanwhile, it can get the fundamental wave equivalent parameters by using Fushi analysis method(instead of electrical bridge methods). The measuring frequency of 500A wideband power signal waste source setting is point frequency. According to the working frequency is can be divided into two parts:
（1）、Measuring frequency: 1kHz-200kHz；Output voltage: 1V-200V（120VA）；
（2）、Measuring frequency: 1kHz-200kHz(Can draw magnetic hysteresis loop);
500kHz-1MHz，the output voltage is 1V-200V（80VA）；We can make the product according to the requirements of the customers except for the above measuring frequency.
