The unit RK-5 is designed for speed control and overspeed shutdown of diesel engines. It is the frequency of the incoming signal that is measured. The speed sensor can either be tachogenerator or magnetic pickup, mounted at the timing gear or at the flywheel.
The relay is delivered in three versions, depending on the incoming frequency:
- RK-5-1 0-100Hz Tachogenerator
RK-5-2 0-2000Hz Pickup at the timing gear
RK-5-3 0-8000Hz Pickup at the flywheel
