Use
SWIFT 30 A (aluminum) for
SWIFT 30 T (titanium) for low weight, high sensitivity
high fatigue life, durability
Maximum usable rpm 2,200
Maximum speed 240 kph (150 mph)
fits rim size (usable range)

Input voltage required 10–17 VDC
Input power required per transducer 30 W maximum (22 W typical)
Output voltage ± full scale calibrated load
±10 V
