Operating Temperature Range
Min -50°C / Max 85°C (100 hours at 125°C)
Electrical Connection
• Internal wiring is designed according to each application. For thermocouples, it can be either common negative or wire to wire. A PT 100 sensor can be installed for the cold junction temperature compensation
• Each base is wired to the main male connector with high temperature PVC insulated cable
• The pipe is fitted with dispensed polyurethane, for perfect insulation, sealing and vibration protection
• Electrical connections can be customer specific or standard JAEGER connectors. For NATO application the connectors are from SOURIAU or JUPITER
Usually 3.2 Kg/meter
Up to 6 metres
Usually 60x60mm, 30x30mm, 50x50mm
Other Dimensions
Up to 90mm x 90mm
IP54 or 64
Other Features
• The pipes can be considered as mechanical parts offering the corresponding savings, allowing sensors with identical extension cord lengths
• Mounted with one bracket, approximately every 1.5 metres


Your ability to perform is based on a need for absolute reliability.

Enclosed within aluminium profiles, using typical 60mm x 60mm extrusions, the CMR PIPEHarness™ protects your critical wiring on the engine platform and internally, within the crank case.

Typical applications of the Gas Engine Ignition PIPEHarness™ range includes:
• Transmission of power supply for ignition coils
• Connection of sensors used for monitoring gas and dual fuel engines
• Transmission of measuring signals

Main benefits include:
• ‘State-of-the-art’, in terms of installation cost:
- The pipe is inside the oil sump, so machining time is reduced as only one through wall connection is required
- The sensor requires a minimum of securing inside the engine block
- Economy on sensor cables (which do not need to go outside the casing)
• Waterproof for fixing inside crankcase (for example for bearings temperature measurement transmission)
• Outputs made by a single fitting through of the crankcase
• Engine esthetics maintained due to absence of external cabling
• Very easy maintenance: only 1 coupling and 1 plug need to be loosened.
• Pipe can be installed through the engine block doors or similar aperture, which simplifies the installation operations.
