Industrial machine vibration sensor Amphenol PC421VP-50-IS enabling proactive maintenance strategies
Wilcoxon LPS Series 4-20 mA Vibration Transducers
Product Overview
Wilcoxon's LPS Series 4-20 mA loop-powered vibration transmitters are self-contained units designed to directly input vibration data into Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS). This enables plant personnel to continuously monitor overall vibration levels, trend machine health, correlate vibration to operating conditions, and schedule maintenance proactively. By providing a simple 4-20 mA signal that correlates to average machine vibration, these sensors offer a convenient, reliable, and cost-effective solution for predictive maintenance (PdM) strategies, reducing outages and downtime. They are ideal for monitoring critical machinery and guiding Condition Based Maintenance (CBM) programs, even in the absence of dedicated vibration analysis technicians. Available with various output signal types (peak, true peak, RMS) and measurement units (velocity or acceleration), these transducers can be configured with specialized features like dual outputs for temperature or dynamic signals, and options for hazardous area installations.
