Description
The 3500/45 Position Monitor is a 4-channel instrument that
accepts input from proximity transducers, Rotary Position
Transducers (RPTs), DC Linear Variable Differential Transformers
(DC LVDTs), AC Linear Variable Differential Transformers (AC
LVDTs), and rotary potentiometers. The monitor conditions the
input and compares the conditioned signals with userprogrammable alarms.
The type of measurement and transducer input determine which I/O
modules are required. See Transducer Types for Position Measurements
on page 11, Front and Rear Views of 3500/45 Position Monitor on page
14, and I/O Modules for AC LVDTs and Rotary Potentimeters on page 16.
You can program each channel using the 3500 Rack
Configuration Software to perform the following functions:
n Axial (thrust) Position
n Differential Expansion
n Standard Single Ramp Differential Expansion
n Non-standard Single Ramp Differential Expansion
n Dual Ramp Differential Expansion
n Complementary Differential Expansion
n Case Expansion
n Valve Position
