The FT-1500 is an unique instrument for conducting rpm measurement in applications where conventional tachometers exhibit poor performance or are completely incapable of achieving the desired results. Utilizing FFT technique, it extracts rotational speeds from complex signals generated by rotary objects.
There is no need for affixing a reflection marker or any other material on the rotating shaft. The FT-1500 can measure the rpm even if the shaft is not accessible.

Features

Non contact measurement
Measurement on inaccessible shafts
A wide variety of sensors to cover various applications
Various output functions provided as standard enabling in-line use and quality control
Easy to install DIN sized body
