PT9301-EXT Harsh-environment series

PT9301-EXT Harsh-environment series



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 selfgenerating 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 NEMA-4 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”.
