Lehmann & Michels (LEMAG)
PJ Diesel Engineering, is the Danish agent for Lehmann & Michels GmbH & Co. (LEMAG®).
LEHMANN & MICHELS has specialized in production of measuring instruments since 1911.
LEMAG® mechanical indicators are known worldwide. There are three different types of mechanical indicators available for slow (LEMAG 50-M3), medium (LEMAG 30- M2) and high speed engines (LEMAG 25-M).
The first electronic indicator for pressure measuring was introduced in 1985. PREMET®electronic indicators are known due to their accuracy and reliability. PREMET L, LS and XL electronic pressure indicators are designed to be used on diesel, gas, steam and compressor engines. The use of heavy fuel oil doesn’t restrict the applicability of the PREMET® indicator. It is possible to draw diagrams of indicated power, mean indicated pressure, power distribution, ignition-pressure distribution and amount of revolutions per minute.
The LEMAG PREMET® Online was introduced in May 2001.
It is a logical extension to the company’s production of mechanical end electronic indicators.
This computerized MIPsystem enables 24H monitoring of engine performance. The cylinder pressure changes are measured individually in each cylinder at the same time and verified by comparison with the current crankshaft position through a central computer.
