Rigid PIPEHarness™ Wiring Systems

Rigid PIPEHarness™ Wiring Systems

Our PIPEHarness™ systems, first patented in 1972, set the global industry standard for robustness. Enclosed within aluminium profiles, using typical 60mm x 60mm extrusions, the CMR PIPEHarness™ protects your critical wiring externally on the engine platform and internally, within the crank case.

Operating Temperature Range
Max 105°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 and sealing
• Electrical connections can be customer specific or standard JAEGER connectors. For NATO application the connectors are from SOURIAU or JUPITER
Weight
Usually 3.2 Kg/meter
Length
Up to 6 metres
Width
Usually 60x60mm, 30x30mm, 50x50mm
Other Dimensions
Up to 90mm x 90mm
Insulation
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

Description

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

Our rigid pre-cabling systems are used both externally on the engine platform and internally within the crank case. The range includes:

• Thermometric & Pyrometric pipes (CT™, CPT™ & CTT™, PRY™)
• Inside Crankcase Thermometric pipes (CTC™)
• Complex & Multi-Service (CAW™, CPW™, MSP™)
• Patented Ignition Pipes for Gas engines, including Coils and Pulse transmission (CAL™, CAC™, CMB™)
• Smart Connecting pipes using CAN open, J1939 protocol (SCP™)

CMR’s PIPEHarness approach improves aesthetics, reduces cost of installation (build time) and negates the chance of sensor inversion upon connection.

Production technologies applied included automated cut, strip and termination, build board assembly, best in class test systems support by Cirris test software

As you would expect, many systems are also UL, CSA and ATEX classified, while adhering to marine approval standards.

Key benefits include:

• The pipe systems reduce installation time of electrical sensors on a diesel and gas engine significantly as the pipe is completely pre-wired

• No special skill is required for assembly and maintenance as all the connections are made via plugs and sockets (plug and play)

• It also allows to subcontract manpower and electrical engineering as the pipe is

• The pipe can gather various signals such as :
- exhaust gas temperature
- jacket water temperature
- main and thrust bearing temperature
- spark ignition cables
- cylinder liner and exhaust valve temperature.

• As an alternative for junction boxes, short pipes are available for wiring:
- Pressure sensors and switches
- Various temperature sensors and switches
