Digital watt loss tester Dw22 is single sheet core loss tester which is useful to evaluate iron loss of electrical steel sheet CRGO, CRNO material and suitable for testing EI lamination, Motor Stamping, Fan motor stamping etc. Single sheet tester is suitable for quick & tentative idea of iron loss of sample. however for precision measurement user has to use Epstein Tester.
Digital watt loss tester DW-22 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 micro-controller appropriate to specimen’s data (core area and weight) gives result as watt/kg
Digital watt loss tester DW-22 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. Digital Iron Loss Tester Dw22 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. As each probe requires individual calibration with meter so it is necessary to decide for one probe or two probe option at the time of order.
