EGT sensor
Products
Exhaust temperature sensor, EGT
How is an EGT sensor constructed?
The EGT sensor consists of four parts.
- Wires
- Metal casing
- Ceramics (insulation)
- Sensor
My EGT sensor show the wrong values.
If your EGT sensor previously worked but now displays an error or no value, it is likely that the ceramic inside the sensor has cracked, resulting in a short circuit caused by wire contact.
Why does an EGT sensor fail?
In order to measure high temperatures, the sensor requires protection for its cabling. This is achieved by using ceramics in the metal part. However, ceramics are fragile and can easily crack. It's crucial to handle the sensor with care to prevent any damage. If the ceramic cracks and is exposed to motor vibrations, it may stop working due to a short circuit.
Open or closed tip on EGT sensor?
A closed-tip EGT sensor is more protected but reacts more slowly to temperature changes than the equivalent open-tip sensor.
Choice of EGT sensor
If your EGT sensor is to be mounted in a manifold, a closed top is recommended as it is the most protected and potentially has a longer life than the equivalent with an open tip.
