Exhaust gas temperature (EGT) sensor

Yes, marine monitoring products in this range are generally designed to be compatible with the NMEA 2000® protocol. This enables easy integration and seamless communication with other NMEA 2000®-certified equipment on board your vessel, allowing EGT data to be displayed on compatible screens.

Yes, an EGT probe is an analog sensor. To integrate it into an NMEA 2000® network, it typically requires a temperature interface module (such as a compatible NMEA 2000® temperature module) that converts the probe's analog signal into NMEA 2000® digital data readable by your displays and monitoring systems.

The EGT probe is designed to monitor exhaust gases from marine engines in general. Its compatibility will mainly depend on the physical possibility of installing it on your engine’s exhaust system and its connection to a compatible NMEA 2000® interface module. It is not limited to a specific engine brand, but installation may require adaptations.

EGT probe data, once converted to NMEA 2000® by an interface module, can be displayed on any multifunction display (MFD) or NMEA 2000®-compatible data display from brands such as Raymarine, which supports engine temperature parameter display.

Yes, the EGT probe is designed to be integrated into existing engine monitoring systems, provided these systems are NMEA 2000® compatible and an appropriate interface module is used to convert the probe’s signal. This allows EGT monitoring to be added to your digital dashboard.

The EGT probe itself generates an analog temperature signal. To integrate it into a J1939 engine network, or to make J1939 data visible on an NMEA 2000® network alongside EGT probe data, a converter or gateway (e.g., a J1939 to NMEA 2000® gateway) would be required to ensure protocol compatibility.

The ideal location to install an EGT probe is usually in the exhaust manifold or riser, immediately after the engine’s exhaust gases exit and before any significant dilution or cooling (e.g., before cooling water is injected into the exhaust). This ensures an accurate measurement of combustion gas temperature.

Installing an EGT sensor involves working on the engine’s exhaust system, which may require marine mechanical and electrical skills. It is recommended to use a qualified professional or to strictly follow the installation instructions provided with the product to ensure correct and safe installation.

Installation may require standard marine mechanics tools, as well as more specific tools for drilling and tapping the exhaust manifold if a port is not already available (e.g., a drill bit and tap of the appropriate size for the transducer’s thread). It is important to consult the installation manual for the exact list of required tools.

The EGT probe typically connects to the interface module via specific wiring (often a type K or J thermocouple, depending on the probe). Detailed connection instructions, including the wiring diagram and specific terminals on the module, are provided in the user manual of the compatible interface module.
