Kind Tips
To ensure optimal performance and longevity of your Exhaust Gas Temperature (EGT) Sensor, please follow these essential guidelines during selection, installation, and operation.
1. Correct Selection for Optimal Match
Select the appropriate model based on the actual exhaust temperature peak (e.g. diesel engine is usually 800°C, gasoline engine may be higher), accuracy requirements (e.g. ±7°C@1000°C) and communication protocol (e.g. SENT). Thermocouple type (e.g. K type) is a common choice.
2. Proper Installation is Critical
The installation location should represent average exhaust temperature, typically after the turbine or before the DPF. Insert the probe deep enough to center the exhaust airflow, avoiding heat dissipation from the pipe wall. The stepped design facilitates secure mounting and ensures a leak-proof seal.
3. Ensure Reliable Electrical Connections
Always use shielded cables and proper grounding to protect the signal from electromagnetic interference, especially from ignition systems. For thermocouple-based sensors, ensure matched compensating cables or a correct digital interface are used to maintain signal accuracy.
4. Mind the Environment and Maintenance
The sensor operates in a harsh environment. Choose a mechanically robust design to withstand vibration and thermal shock. Periodically inspect for carbon buildup that can slow response time, and utilize the built-in diagnostics to monitor for fault codes, facilitating proactive maintenance.
