Turbocharger Telemetry at 200,000 rpm
Manner Sensortelemetrie has developed a miniature 4 channel system which is capable of operating at 200,000 rpm for prolonged periods. This allows the measurement of bearing temperatures, torque and blade vibrations online. The sensor signal amplifier screws into the end of the turbo shaft with the surrounding annular stator antenna attached to the turbo inlet duct. The sensor signal amplifier is 35 mm long, 6 mm diameter and weights 5 g.
The measurement signal and the energy are transmitted without contact via the inlet port. Up to 4 channels can be transmitted in parallel with 16 bit resolution. The maximum ambient operating temperature is 160 deg C.
