Rotational Speed Sensors
Accurate Technologies Inc. (ATI) offers the PICOTURN 2G rotational speed sensor for turbochargers. Compared to optical or magnetic sensing systems, the PICOTURN system is proven as a rugged, reliable, simple, accurate and cost effective solution. , using a compressor mounted solenoid sensor that detects and counts compressor vanes individually, generating a standard TTL/CMOS output signal. Maximum wheel speed measurement is 400,000 rpm, with a minimum operating speed of 390 rpm.
The open system architecture and the modular system design allow an easy integration into existing measurement systems as a stand-alone solution or optionally with the PT2G-BD or PT2G-BX signal conditioning boxes. The preferred turbo compressor wheel material is aluminum; titanium wheels require individual testing to verify compatibility with the PICOTURN sensor.

The PICOTURN system benefits from high sensitivity, allowing a large distance between sensor and the rotating vanes in the range of 1 at 0.6mm vane thickness. Various sensors are available to accommodate numerous user cases differentiated by the length and thread the sensor head.
