The PT9301 is a combination position and velocity
transducer for demanding long-range applications
requiring a linear position measurements in ranges
up to 1700”. A precision plastic-hybrid potentiometer provides accurate position feedback while a
self-generating DC tachometer provides a velocity
signal that is proportional to the speed of the traveling stainless-steel measuring cable.
As a member of Celesco’s innovative family of NEMA4 rated cable-extension transducers, the PT9301 offers numerous benefits. It installs in minutes, functions properly without perfectly parallel alignment,
and when its cable is retracted, it measures only 6”.
