Dw33 is single sheet core loss tester which is useful to measure watt loss of electrical steel sheet CRGO, CRNO material and suitable for testing EI lamination, Motor Stamping, Fan motor stamping etc.

DW-33 is provided with a stroboscopic probe when placed on specimen, closes the magnetic path between probe and specimen. Probe has two coils primary and secondary (like transformer). When power applied to primary coil and detected by secondary coil appropriate to specimen data and measure voltage, current and power. Then measured data calculated by microcontrollerappropriate to specimen's data (core area and weight) gives result as watt/kg

DW-33 frequently used to measure the properties of both fully processed and semi-processed non-oriented and magnetic lamination steel sheet. It may also be used to evaluate oriented electrical steels in either they are sheared or stress-relief annealed condition.

We have invented & developed singe sheet test method in year 1995. DW33 is fourth generation equipment with most advanced technology and having precision measuring circuit. Moreover it comes with option to

connect two size of probes. Small probe comes with equipment as standard. And big probe is optional, to achieve better accuracy in big size sample testing. Aseach probe requires individual calibration with meter so it is necessary to decide for one probe or two probe optionat the time of order.

EP-400 is designed to measure AC magnetic properties of flat rolled magnetic materials at high frequency by using Wattmeter, Ammeter, Voltmeter and Source. Epstein bridge test method is a fundamental method for evaluating the magnetic performance of flat-rolled magnetic materials in either sheared or stress relief annealed condition. This test method is suitable for design, specification acceptance, service evaluation, and research and development.

EP-400 has digital controlled crystal accurate 16 Bit sine wave Generator, which provides 25 Hz to 450 Hz harmonics free non distorted power for testing of specimen. It has in built measuring meter, like Flux Voltmeter, RMS Voltmeter, RMS Ammeter, Peak Ammeter, Wattmeter and Power Factor meter with digital sampling method. These measuring devices are (temper proof) precisely calibrated to achieve high accuracy and long term stability. Accuracy and stability of EP-350 is better than specified in national and international standards. (Reference to ASTM: 343, IEC: 60404-2, BIS: 649)

Fully Automatic Test Method

You can get the complete test report at nine different induction points within few minutes. You only need to insert strips in the bridge and enter the weight, length and density of material in software. EP-400 starts taking result at your defined nine different induction point automatically. For testing at each induction, it sets frequency, flux volt & induction automatically using digital sampling method by micro controller. After competition of testing, software generates report in Excel sheet.
