Wilcoxon Sensing Technologies 4-20 mA LPS Series Transducer Selection Guide
Product Overview Wilcoxon's 4-20 mA Loop Powered Sensors (LPS) are self-contained vibration transmitters designed to integrate directly with Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS). This capability allows plant personnel to input vibration information directly into their control systems, enabling continuous monitoring of critical machinery, trending of overall vibration data, correlation with plant operating conditions, and proactive scheduling of maintenance tasks. LPS transducers provide a simple, reliable, and cost-effective means to monitor machine health, prevent failures, and support Condition Based Maintenance (CBM) programs, even in the absence of dedicated vibration analysis technicians.
Key Benefits:
Direct integration with PLC/DCS for real-time vibration monitoring.
Enables trending of overall vibration levels and correlation with operating conditions.
Supports Condition Based Maintenance (CBM) programs.
Cost-effective and convenient machine health monitoring.
Available with various output signal types (peak, true peak, RMS) and measurement units (velocity, acceleration).
Specialized frequency-banded options for targeted diagnostics (low frequency for imbalance/alignment, high frequency for cavitation).
Dual output options for simultaneous vibration and temperature or dynamic signal monitoring.
Certified for hazardous area installations (Intrinsically Safe and Explosion Proof).
Application Scenarios:
Predictive maintenance and vibration monitoring of industrial machinery.
Monitoring critical plant assets for early detection of issues like shaft misalignment, rotor imbalance, gear failure, and bearing faults.
Applications requiring integration with existing plant control systems (PLC/DCS).
Environments with hazardous area classifications.
Trending overall vibration for general machine health assessment.
Targeted monitoring of low-frequency (imbalance, alignment) or high-frequency (cavitation) vibration issues.
