MQ 0407

MQ0207-K_1_03.jpg

The MQ 0407 bimetallic instrument is intended especially for thermal monitoring of transformers, cables, etc. due to its slow reaction to current changes. It indicates mean RMS current value during the measuring period of the instrument. The instrument does not react to short current pulses essentially. Maximum mean value in a response time period is indicated by the red slave pointer. The latter can be reset or set to zero by means of a knob which can be sealed.

MQ 0407 is the same as the one on the photo, except its front frame is 48x48 mm. Special instrument design enables quick replacement of the scale both in case of a new or an already used instrument. This is especially suitable for instruments which are connected to current transformers.

The exchangeable scale has a number of advantages:

  • quick and simple adaptation of the instrument to variable user technical requirements

  • shorter delivery time

  • allows flexible planning


    • Features:
  • For measurement of maximum AC currents

  • Good read-out survey on larger distance

  • Exchangeable dial

  • Resistance to mechanical vibrations

  • Protective cover for terminals (optional)

  • Instrument according to DIN 43700
