Short descriptionThe RPM-8000-DC was special developed for DC engine RPM measurements. This field of engineering becomes more important in the future regarding the low noise design of compact drives, e.g. in the automotive industry for electrical window opener, slide roofs and seat adjustments. The RPM-8000-DC will used on machines, where the drive shaft is not accessible or where conventional sensor mounting is to time and money expensive. The device will simply connected in series with the engine power supply, without any influence to it. Every transition between two successive collector lamellas generates a small fluctuation of the engine current. This variations will detect, cleaned from interfering pulses and noise, amplified and converted to a TTL compatible frequency signal, which is per design proportional to the engine RPM. Simultaneously a potentiometer adjustable linear analog output signal will generated.
The sensor electronics will supplied from a separate
voltage input in the range from
