Speed Sensor (Engine)
Illustration 1 g00792774
Speed sensor for the engineThe speed sensor is used in order to sense engine speed.The speed sensor is a passive magnetic sensor. The sensor produces an analog signal.The sensor is an input to the tachometer. The tachometer uses the signal from the sensor in order to calculate the engine speed.ReferenceSee Systems Operation, "Guages" for information on the tachometer.Thermocouples
Illustration 2 g00792788
ThermocoupleThe thermocouples monitor the temperature of the following components:
Turbocharger inlet
individual exhaust portsThe thermocouples are inputs to the pyrometer. The pyrometer uses the signal from the thermocouples in order to display the temperatures of the components.ReferenceSee Systems Operation, "Guages" for information on the pyrometer.
