PICOTURN-2G: The Smart Sensor to Measure Your Turbochargers Speed

PICOTURN-2G represents the second generation of acam's well established system to measure the rotational speed of turbochargers compressor wheels. As a fully integrated and compact solution the PICOTURN-2G is a miniaturized sensor system that perfectly suits to applications in the engine bay. The sensors are IP 67 proof and provide a standard TTL / CMOS output signal, whereas each edge corresponds to one vane of the compressor wheel. The open system architecture and the modular system design allows an easy integration into existing measurement systems as a stand-alone solution or optionally with acam's PT2G-BX or PT2G-BD signal conditioning boxes.
