Description
The 3500/45 176449-04 Position Monitor is a 4-channel instrument designed for industrial automation, accepting inputs from proximity transducers, Rotary Position Transducers, DC and AC LVDTs, and rotary potentiometers. Each channel conditions signals with impedances of 10 kΩ for Proximitor/RPT, 1 MΩ for DC LVDT, 137 kΩ for AC LVDT, and 200 kΩ for potentiometers, providing thrust sensitivity of 3.94–7.87 mV/µm and differential expansion sensitivity of 0.394–0.787 mV/µm. The 3500/45 176449-04 Position Monitor uses 3500 Rack Configuration Software to program axial position, dual ramp, case expansion, valve, and differential expansion monitoring. Alarm setpoints are adjustable from 0–100% full-scale with ±0.33% typical accuracy. Consuming 7.7 W per channel and operating from -30°C to +65°C, the 3500/45 176449-04 Position Monitor delivers real-time measurements for automation control and predictive maintenance.
Applications
The 3500/45 176449-04 Position Monitor tracks turbine axial and thrust positions using Proximitor inputs at 10 kΩ impedance, generating thrust measurements with 3.94–7.87 mV/µm sensitivity. Alerts are triggered when values exceed programmed thresholds.
Measure Differential Expansion in Heat Exchangers
The 3500/45 176449-04 Position Monitor conditions DC LVDT signals at 1 MΩ, producing differential expansion data with 0.394–0.787 mV/µm sensitivity. Alarm setpoints from 0 to 100% full-scale notify operators of mechanical movement.
Control Valve Positions in Process Systems
The 3500/45 176449-04 Position Monitor measures rotary potentiometer signals at 200 kΩ, delivering valve position readings with ±0.33% full-scale accuracy for automated valve control.
Compare Dual Ramp Expansions in Compressors
Using AC LVDT inputs at 137 kΩ, the 3500/45 176449-04 Position Monitor records dual ramp expansions with 0.394–7.874 V/mm sensitivity, supporting predictive maintenance and operational adjustments.
Record Case Expansion in Large Motors
The 3500/45 176449-04 Position Monitor monitors case expansion signals, providing real-time measurements at 7.7 W per channel while operating from -30°C to +65°C, enabling

Alarm Setpoints |
Use the 3500 Rack Configuration Software to set alert and danger levels for the direct values measured by the monitor. Alarms are adjustable from 0 to 100% of full-scale for each measured value. However, when the full-scale range exceeds the range of the transducer, the range of the transducer will limit the setpoint. |
