The Q.bloxx D107 is a new measurement module for the acquisition of frequencies and incremental signals. Due to its fast signal conditioning capability with a clock speed of 288 MHz, the new module is suitable for extreme measurement of rotational speeds, which were not previously possible in this price range.
Racing car engines can produce rotational speeds of up to 20,000 rpm. The special challenge in measuring these speeds is the extremely rapid changes in rotation of up to 100,000 rpm per second. It is therefore essential that the index gap in the gearwheel, used for recording purposes, comprises two missing teeth instead of one. A single missing tooth could be confused with a fast decrease in rotational speed.
The D107 module can detect the missing teeth at maximum speeds, and correct each measured value in real time. This contributes to stabilizing the measured speed values, and readings are not influenced by the index gap.
