The BQ 0107 is designed for mounting into supervision panels of power distribution or transformer stations where DC current and voltage measuring instrument is required.
Its front frame is 144x144 mm. It has 90 degree dial.
The measuring system includes a core magnet, which is insensitive to external fields. The moving-coil is mounted on spring bearings, therefore the measuring system is highly resistive to mechanical shocks and vibrations. The scale graduation is practically linear throughout the whole range. 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 that are connected to a transducers with standard type current output or to separate shunts with rated voltage drop (e.g. 60 mV).
The exchangeable scale has a number of advantages:
Special versions are available for panel mounting into ships. These are mechanically resistant and additionally sealed instruments. The instrument case is marked by an anchor and a capital letter L at the end of the type designation.
