Product Overview
Wilcoxon's 4-20 mA LPS Series transducers are self-contained vibration transmitters designed to integrate directly with Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS). These loop-powered sensors enable plant personnel to continuously monitor overall vibration levels, trend machine health, correlate vibration data with operating conditions, and schedule maintenance tasks. They are crucial for Condition Based Maintenance (CBM) programs, providing essential vibration information even without a dedicated vibration analysis technician. Wilcoxon LPS transducers offer a cost-effective and reliable solution for monitoring critical machinery, preventing failures, and reducing downtime.
