Moving-iron ammeters LE-3P

 The LE-3P moving-iron instruments are designed for the measurement of alternating currents of frequencies ranking between 40 and 400 Hz.

Type LE-3P instrument is designed to be used for measurements in industrial and scientific laboratories, test stations and wherever high accuracy of measurement, especially with distorted voltage or current waves, is required. The LE-3P measures rms value.

General information:

  • The LE-3P moving-iron instruments are designed for the measurement of alternating currents of frequencies ranking between 40 and 400 Hz.
  • The LE-3 measures rms value.
  • Measuring ranges of ammeters and voltmeters are changed by means of rotary selector switches.
  • The moving element is taut-band suspended by which the sensitivity of meter to vibrations,
    shocks, etc is minimized.
  • Type LE-3P moving-iron instruments have an up-to-date measuring element located in a double electromagnetic screen which minimizes the effect of external magnetic fields upon meter readings.
  • Type LE-3 instruments are very easy in use and very reliable.
  • The measuring element of instrument is operating in conjunction with a built-in current transformer
  • The pointer, narrowed at the end, and mirror scale ensure accurate readings free of parallax error.
