Description

The3500/45Position Monitor is a 4-channelinstrument that accepts input from proximity transducers, Rotary Position Transducers (RPTs), DCLinear VariableDifferential Transformers (DCLVDTs), ACLinear VariableDifferential Transformers (ACLVDTs), and rotary potentiometers. The monitor conditions theinput and compares theconditioned signals with user-programmablealarms.

Thetypeofmeasurement and transducer input determinewhich I/Omodules arerequired. See Transducer Types for Position Measurements on page10., SeeFigures and Graphs on page12., and See I/OModules for ACLVDTs and Rotary Potentimeters on page14.

You can program each channelusing the3500Rack

Configuration Softwareto perform thefollowing functions:

•Axial(thrust) Position

•DifferentialExpansion

•Standard SingleRamp DifferentialExpansion

•Non-standard SingleRamp DifferentialExpansion

•DualRamp DifferentialExpansion

•Complementary DifferentialExpansion

•CaseExpansion

•ValvePosition

Themonitor channels areprogrammed in pairs and can perform up to two ofthesefunctions at a time. For example, Channels 1and 2 can perform onefunction whilechannels 3 and 4may perform thesameor a different function.
