Mechanical Cylinder Pressure Indicators
LEMAG mechanical indicators are known worldwide.
There following types of mechanical indicators available:
LEMAG Type LS peak pressure indicator with GL type approval
LEMAG indicator Type 25-M for high-speed engines
LEMAG indicator Type 30-M2 for medium-speed engines
LEMAG indicator Type 50-M3 for slow-speed engines
LEMAG PEAKmag peak pressure indicator
LEMAG Planimeter for accurate indicator P/V diagram measurements
Peak Pressure Indicators
LEMAG Peak Pressure Indicators measure the firing pressure of internal-combustion engines. In order to be free of residues, the indicator valve should be briefly blown through before starting the measurement. To take readings the instrument has to be connected to the indicator valve by means of a standarized connecting nut.
The LEMAG Peak Pressure Indicator is now ready for use. When the indicator valve is open the value on the pressure gauge will rise. Once it has reached the maximum pressure, close the indicator valve and reset using the vent screw fixed on the side. and will remain on the maximum. By notice this value, this indicator valve must be closed and the instrument has to be reseted by using the vent screw fixed at the side. After that, the device is ready for taking new readings.
LEMAG Peak Pressure Indicators are designed for single measurements only (not for continuous operation). The respective measuring period should not exceed 30 sec. This is not a problem in normal practise, as peak pressure is indicated after 5 sec.

For accurate measurement of indicator P/V diagrams
Planimeters types PT1 and PT2 are perfect tools for accurately measuring indicator diagrams. Simply trace the lens along the diagram.
You only need to set the centre of the tracing lens on the engine’s P/V diagram and trace it along the curve. On completion you can easily calculate the indicated power.
The planimeters are delivered in solid instrument cases to ensure safe handling and maintain accuracy.
Planimeter Type PT1
* Mechanical
* Metric system
* Measures areas at different scales with a fixed vernier unit of 0,1cm2
* Working area up to 50cm x 50cm or 70cm diameter circle
Planimeter Type PT2
* Mechanical
* Metric / Imperial system
* Measures areas at different scales with a variable vernier unit of 0,1cm2 or 0,05cm2 for small areas
* Working area up to 70cm x 70cm or 100cm diameter circle
