PICOTURN - Rotational Speed Sensing
Industry Leader & World Supplier of Picoturn Systems
PicoTurn systems are used to measure turbocharger rotational speed with high accuracy. PMT has been the Sales and Technical support channel for PicoTurn products for almost 20 years. We are the ONLY TECHNOLOGY CENTER with the ability to calibrate turbocharger speed sensors.
Picoturn is a test system for measuring turbocharger rotational speed using the eddy current reduction technique. This technique directly senses each vane of the turbocharger wheel with a speed sensor that is mounted in a hole bored into the turbocharger housing. PicoTurn measures rotational speeds to 400,000 rpm, requires no modification of rotating parts, and senses the compressor wheel directly. It is compatible with single and two-stage turbocharger systems.
PicoTurn offers IP67 compliant sensors, standard digital TTL and CMOS output signals, compact housing, and a programmable number of vanes. The system has open architecture and works well stand alone or fits easily into another measurement system. PicoTurn is ideal for engine testing in passenger cars and commercial vehicles, as well as other applications that require high precision rotational measurement.
The PICOSTRAIN integrated circuits are realized without any analog component. Again, acam uses its TDC technology to set new standards in circuit design and takes the advantages of this principle like:
