DV301
The DV301 is a combination position and
velocity transducer for full-scale measure-
ment ranges from 2 to 100 inches. A preci-
sion plastic-hybrid potentiometer provides
accurate position feedback while a self-gen-
erating DC tachometer provides a velocity
signal that is proportional to the speed of the
traveling stainless-steel measuring cable.
