2. INTRODUCTION
The new Microgate reflection photocell Polifemo is outstanding for its attractive design, conceived
to meet the requirements of safety standards. Its unique optical design guarantees a high range and
greater accuracy of measurement. In addition, special optical and electronic features guarantee
maximum reliability even in poor outdoor light.
Internal power supply is provided by rechargeable batteries (the ‘smart’ recharge circuit is built into
the photocell) which can be replaced with two normal AA size batteries, and allow 18 hours of
autonomous functioning. Its microprocessor management and programming switches also make it a
very versatile instrument.
Radio transmission of an impulse is a critical phase in timekeeping. The timekeeper and/or trainer
have always displayed a certain scepticism towards timing via radio because of the fear of losing
timing data and of inaccurate time taking.
Polifemo-Radio is a highly innovative instrument in the field of radio transmission of timing
impulses. Thanks to technical innovation, the old impulse transmission systems have been replaced
by data transmission which ensures maximum precision and reliability thanks to transmission
redundancy and the use of error correction codes.
Built into the Polifemo-Radio photocell is an EncRadio-SF, the device for radio transmission of
impulses which is part of the LinkGate-SF system. A high-performance top-quality FM radio
module (433MHz 10mW) is used for transmission.
