Turbo Charger Blade Vibration Measurement
- blade telemetry for turbochargers
Manner’s sensor telemetry applications, especially as employed on the so called blades of a flow and compression system such as a turbo charger, are important to many customers. The high frequency oscillations of these blades have already been measured and precisely recorded in numerous cases with the assistance of our measuring system. This enables important information to be obtained for the design of compressor blades in respect of stability and aerodynamics.
At maximum revolution speeds, the blade or paddle vibrations are precisely measured, and as standard, transmitted to the evaluation unit or computer using non-contact technology. The miniaturised construction and the extremely simple mounting are the result of years of development work in cooperation with the turbo charger industry.
The electronics and transmission antenna are contained in a cartridge shaped housing that weighs a mere 5 grams and has a length of 35 mm. It is screwed on to the shaft thread at the turbo charger input. The inductive coupling is conducted at the inlet and can process up to four sensor signals in parallel. The measured signal has a digital resolution of 16 bit, the rotor electronics a temperature resistance of 160°C.
