  • Reliable operation and visualization of load on a counter-pointer display with an additional Vernier scale.
  • Digital indication with the use of light-emitting diodes changing their colour depending on a mode of operation:
    • green(easy-to-use, easy-eye) – normal mode,
    • orange – by 95% of the prescribed ultimate load,
    • red – by 100% of the prescribed ultimate load.

Additional information

  • MI-140S has a box-like case made of aluminum alloy containing no less than 6% of magnesium covered with armored-film glass. The case and the glass are tightly joined due to elastic gaskets. 
  • MI-140S (counter-pointer) has a dial with an indicator powered and controlled with a low-current stepping motor. Pointer readings are backed up on four seven-segment LED matrices.
  • MI-140S features integrated microprocessor control, an RS-485 digital circuit for communication with the MU-140 control module and a stabilized power supply circuit, an intrinsically safe circuit at the infeed of the module based on two diodes connected in an infallible series.
  • In addition, MI=140S has an intrinsically safe circuit based on two diodes connected in an infallible series, at the outlet of electric motor winding ends, which together with the ends is compound-filled.
