Digital Iron Loss Tester Dw33 is single sheet iron loss tester which is useful to evaluate iron loss of electrical steel sheet CRGO, CRNO material and suitable for testing EI lamination, Big stamping, etc.

Description

Use of digital iron loss tester

Digital Iron Loss Tester Dw33 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.

How digital iron loss tester works?

Digital Iron Loss Tester 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/kg

Benefit of digital iron loss tester

Digital Iron Loss Tester 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. Digital Iron Loss Tester Dw33 is fourth generation equipment with most advanced technology and having precision measuring circuit.  Moreover it comes with big probe to achieve better accuracy in big size sample testing.

Digital iron loss tester model dw33 is suitable for transformer lamination

Gopal electronics make iron loss tester are widely used in india

Yes you can use dw33 model for iron loss testing of motor stamping which size is bigger than probe core size
