Engine condition monitoring and performance analysis systems
Scandic Diesel is the Canadian representative for LEHMANN & MICHELS GmbH who manufacture diesel, gas, steam and compressor engine condition monitoring and performance analysis systems for the marine industry.
LEHMANN & MICHELS specialise in engine Mean Indicated Pressure (MIP) systems for performance reporting and Condition Based Maintenance (CBM). The MIP range includes electronic indicators, MIP calculators and permanent computerized MIP systems that enable 24hr engine monitoring to shaft power measuring systems. LEHMANN & MICHELS' engine condition and performance analysis systems enable their customers to achieve optimum power and energy use and to enable the customer to carry out
Engine performance analysis for condition based maintenance (CBM)
LEHMANN & MICHELS's engine performance experts provide engine performance analysis to achieve better operational reliability and reducing fuel consumption for their customers. By conducting engine performance analyses it is possible to base maintenance and repair costs on hard facts, not just time.
LEHMANN & MICHELS' engine performance analysis paves the way for Condition Based Maintenance (CBM) and provides detailed information about the actual condition of the engine.
Premet online – permanently installed MIP system
LEMAG PREMET online is a permanently installed Mean Indicated Pressure system developed for measuring of cylinder pressure on diesel and gas engines.
It monitors:
- Mean Indicated Pressure (MIP)
- Maximum cylinder pressure
- Indicated power (KW/hp)
- Torsional vibration
- Expansion pressure
- Main trend function
In this system each cylinder is equipped with a LEMAG PREMET online pressure sensor. These sensors are attached to the existing indicator valves which all measure the cylinder pressure at the same time. This online information is then transmitted to a central computer for analysis.
Premet – mobile electronic indicators
PREMET mobile electronic indicators are designed and manufactured for use on diesel and gas applications for the marine market and mobile / stationary power stations and are not affected or restricted by heavy fuel oil.
It measures:
- Indicated power (KW/hp)
- Mean Indicated Pressure (MIP)
- Power distribution
- Ignition pressure distribution
- Revolution (rpm)
- Torsional vibration
The PREMET software offers several diagrams to analyse combustion and pressure changes in the cylinders. The data can easily be compressed to quickly send files by email or satellite to the main office.
Ship performance monitoring
LEMAG Shaftpower is a permanently installed power measurement system that measures the actual power output of the ship's propulsion engine. The system Shaftpower operates absolutely contact free and does not use strain gauges. The measured power data is displayed in 'real-time'. Comparing the actual data with the pre-set 'propeller curve' helps the operator avoid unintentionally overloading the engine. As an option it is possible to measure fuel consumption, enabling the crew to optimize cruising speed and trim.
