Application report - Speed monitoring of large engines


The engine speed of large diesel engines must be kept within an ideal engine-specific range. Speed monitoring is used as a secondary safety circuit. Both excessive speeds and speeds which are too low must be measured securely and reported. Approval by Germanischen Lloyd (GL) is obligatory.


The programmable speed monitor rotas has a number of functions with which it can be ideally adapted to these requirements.

Start-up override, adjustable switching thresholds and hystereses and a variable signal input for the most different types of sensors are only a few of its functions, which can be programmed at the factory or individually on site on the keyboard.

It has been approved by Germanischen Lloyd for applications at sea.
