Cable-Extension Position Transducer
PT101
Precision Potentiometric Output
Ranges: 0-2 to 0-100 inches
Instrument Grade
Specification Summary:
Based on Celesco’s original string pot design dating back to the late 1960’s, the PT101 has become a standard
throughout the years for literally thousands of applications including aircraft structural testing, hydraulic
cylinder control, valve stem opening, and factory
automation.
Available in full stroke ranges up to 100-inches, the PT101 provides a voltage feedback signal linearly proportional to the position of its traveling stainless steel measuring cable. Additionally the PT101 installs
in minutes and doesn’t require perfect parallel alignment. Simply secure the base to a fixed surface and attach the measuring cable to your moving object.
