Quick Detail

Description

The 140482-01 Prox/Velom I/O Module is a four-channel Prox/Accel Velomitor designed for industrial automation and machinery monitoring. Each channel accepts inputs from proximity and seismic transducers, conditioning signals to deliver precise radial vibration, thrust, differential expansion, acceleration, shaft absolute, and velocity measurements. The module operates at 23.9 V supply voltage, 45.5 mA supply current, and consumes 1.09 W typical power. Operating temperatures range from -30°C to +65°C (-22°F to +150°F) with Internal/External Termination I/O Modules and 0°C to +65°C (32°F to +150°F) with Internal Barrier I/O Modules, with storage from -40°C to +85°C (-40°F to +185°F) and 95% non-condensing humidity. Radial vibration is measured using user-programmable direct filters (-3 dB at 4 Hz to 4000 Hz or 1 Hz to 600 Hz) and gap filters (-3 dB at 0.09 Hz), with Smax from 0.125× to 15.8× machine speed. Thrust and differential expansion maintain ±0.33% full-scale typical ±1% maximum, with direct filter -3 dB at 1.2 Hz and gap filter -3 dB at 0.41 Hz. The 140482-01 allows configurable alert and danger setpoints via 3500 Rack Configuration Software, providing automated protection and reporting of critical machine parameters.

Applications

Monitor Radial Vibration of Rotating Machinery

The 140482-01 measures radial vibration using direct filters user-programmable from 4 Hz to 4000 Hz or 1 Hz to 600 Hz, with ±1% accuracy. Gap filters at -3 dB 0.09 Hz provide precise low-frequency response. This allows operators to detect shaft imbalance, misalignment, or bearing wear in turbines and compressors operating at speeds from 60 cpm to 15.8× running speed.

Track Thrust and Differential Expansion

The 140482-01 measures thrust position and differential expansion with direct filter -3 dB at 1.2 Hz, gap filter -3 dB at 0.41 Hz, and ±0.33% full-scale typical ±1% maximum accuracy. Ramp differential expansion sensitivity ranges from 0.394 V/mm to 7.874 V/mm depending on input, enabling thermal growth tracking in high-load machinery.

Measure Acceleration and Velocity

The 140482-01 conditions acceleration and velocity signals via 1X and 2X vector filters (minimum rejection -57.7 dB), with Smax adjustable 0.125× to 15.8× running speed. This allows precise monitoring of mechanical vibration for automated control and predictive maintenance.

Provide Shaft Absolute and Eccentricity Data

By processing proximity transducer inputs, the 140482-01 calculates shaft absolute and eccentricity data valid for machine speeds 240 cpm to 60,000 cpm. This supports real-time alignment verification and clearance monitoring for high-speed rotors.

Generate Automated Alerts for Critical Parameters

Using 3500 Rack Configuration Software, the 140482-01 enables alert and danger setpoints adjustable 0–100% of full-scale. Alarm accuracy is within ±0.13% of the desired value, allowing immediate response to abnormal vibration or displacement conditions.

Specifications

Competitive Advantage

High-Precision Measurement

Direct filter accuracy ±1%, thrust/differential expansion accuracy ±0.33% full-scale typical ±1% maximum, and Smax range 0.125× to 15.8× running speed provide highly accurate machine data for process control.

Wide Operating Range

The 140482-01 operates from -30°C to +65°C (-22°F to +150°F) with Internal/External Termination I/O Modules and 0°C to +65°C (32°F to +150°F) with Internal Barrier I/O Modules, supporting harsh industrial environments.

Low Power Consumption

Operating at 23.9 V and 45.5 mA with 1.09 W typical power consumption, the 140482-01 minimizes energy usage while continuously monitoring up to four channels of critical machine data.

Flexible Configuration

User-programmable direct filters (4 Hz–4000 Hz or 1 Hz–600 Hz), gap filters (-3 dB at 0.09 Hz), and vector filters allow operators to adapt the 140482-01 to specific machine types and speeds without hardware changes.
