IMPROVING TURBOCHARGER SPEED MEASUREMENT: Time-to-digital converters can provide highly accurate, reliable and cost-effective alternative to mechanical or optical technologies

摘要

Accurately measuring rotational speeds in turbocharger test cells and test vehicles can be challenging. Optical detection systems can be susceptible to dirt, oil and dust. Magnetized pickup components may work loose and damage the turbocharger or engine. And analog vane counting systems must digitize readings by an analog-to-digital conversion (ADC) process.
