Understanding Exhaust Gas Temperature Probe Thermocouple Sensor Accuracy
There are many factors to the "accuracy" any sensor. The most important aspect is what accuracy is needed to satisfy the actual requirement and the evaluation process to get there.
Typically if your EGT sensor is within 1% to 5% of the actual temperature will satisfy most requirements. The major factors are probe accuracy and the indicator accuracy, taking these both in account will give you a close estimate of the actual temperature you are reading from the indicator(s). But remember that what you are really after are two objectives, one is a relative temperature between readings (if you have more than one cylinder) the other is a temperature to obtain optimum performance for your application.
Our EGT probes are designated “special limits of error” are +/- 0.4% of range accuracy tolerance. Using these probes will limit you error of actual reading with the indicator you are using. Make sure to check the accuracy specifications of your indicator.
