Digital Iron Loss Tester Model DW33 (50/60 Hz) for CRGO, CRNO, EI Lamination, Motor Stamping

Product Details

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 micro-controller appropriate to specimen's data (core area and weight) gives result as watt/kgDW-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 fifth generation equipment with most advanced technology and having precision measuring circuit.Big size probe comes with equipment as standard. Big probe is to achieve better accuracy in big size sample testing. Features:- Crystal Accurate inbuilt sine wave generator Testing at 50Hz & 60Hz  Better accuracy than ever 24Mhz MSP-430 micro controller base design Pure sinusoidal source and measure Long terms stability and accuracy maintain Password protected calibration Separate Rotary Knob for Thickness & Tesla LCD display 20x4 Direct readings of W/Kg upto 25 Watt per Kg Connector type low loss probe Big size of specimen possible to test User-friendly operation & portable size Technical Specification:-- Universal Auxiliary Supply = AC 110 V @ 60Hz or 230 V @ 50Hz      [10 VA ± 20%]- Source Capacity = 1.8 Tesla @ 0.5 mm thickness- Test Frequency Range = 50Hz & 60Hz- Magnetic Flux Density Range = 1.0 to 1.8 Tesla   (Weber persquare meter )Dimensions :-Dimension of Main Unit = H 82mm, L 228 mm, W 250 mm Approx.Dimension of Big Probe = H 66mm, L 102 mm, W 44mmCore Size of Big Probe = 60x20 mmDimension of Small Probe = H 66mm, L 82 mm, W 37mmCore Size of Small Probe = 44x14 mmWeight of Main Unit = 5.0 Kg.
