Indicating instrument M1850 (M -1850, M 1850, m1850, m-1850, m 1850)
Indicating instrument M1850 came with tachometer K1803 appliance designed for remote measuring the speed and the direction of rotation of shaft diameters from 20mm to 1125mm main marine engines.
- 1.0 - when the reversing rollers;
- 1.0 - for units with zero within the range of measurement;
- 1.5 - for units with zero left.
Technical characteristics of the devices indicating instrument M1850 :
Indicating instrument M1850 has obscheklimaticheskoe performance of "0";
