DMT-4 Automatic hysteresigraph

DMT-4 automatic hysteresigraph system accords with the standard permanent magnet test system, GB3217-92, used to measure the major and minor hysteresis loops, demagnetization curves, recoil hysteresis loops and initial magnetization curves in different temperature of ferrite, AlNiCo, SmCo, NdFeB and quenched material, and gives the magnetic parameter, Br, Hcb, Hcj, (BH)max, Hk and so on, and could meet different requirements on test function, precision, power capability, reliability, efficiency, price, local environment from laboratory to enterprise's production line.

Main character:

  • Double work mode: Adopt the whole computer mode; or the digital transistor also reads 5 parameters directly, automatic drawing of recording instrument under non-computer mode.
  • Automatization: Including automatic transmission, drift adjusting, automatic calibration, automatically compensate, zero adjust automatically, zero resetting and so on.
  • The size range: Suitable for the great sample test from powder material, Φ3 small stick of the material to Φ260.
  • Various test coils: Allow to adopt prefabricating J coil, B coil, built-in pole coil, and hand mode coil.
  • Simple operation: The mode of the whole computer only needs the keyboard, mouse to finish testing. The non-computer mode needs only to press a start-on button and can finish testing the course entirely.
  • The speed can be chosen: Can choose test period from 5 seconds to 70 seconds to meet the test requirement in different occasion.
  • The practical and friendly: WINDOWS and DOS two test software platforms, reflect practical, reliable, succinct, lucid and lively style fully.
  • Perfect inquiry function: there are more than one hundred thousand test curves could be stored in the warehouse. Click kinds of condition buttons to access necessary curve and then finish the assortment, comparison and filing of products and finally type the form and curve out.
  • Many optional types of print: use ink-jet printer or laser-jet printer to type and publish many kinds of exquisite color, dark curve graph and form. There are Chinese or English character, system of unit, single picture or multi-picture to be chose.

The quality of DMT-4 disposes is reliable. There are large-scale, medium-scale and small-scale,7 models in all, of electro-magnets to be chose. Welcome to enquire and ask for data!

Main technical parameters

  • Integrator steady degree: Zero adjusting automatically is superior to 0.1~0.2% / of 90 seconds (relate to shelf location)
  • B/J channel: repetitiveness is superior to 0.25%, the error is below 0.5% (full-scale value)
  • H channel: repetitiveness is superior to 0.25%, the error is below 0.5% (full-scale value)
  • (BH)max channel: repetitiveness is superior to 0.5%, the error is below 0.5~2% (change with the sample kind)
  • The magnetizing power supply: the maximum output power is 100KW, with perfect protection technology and intellectual control
