Wilcoxon Sensing Technologies 4-20 mA LPSTM Series Transducer Selection Guide
Product Overview
Wilcoxon's Loop Powered Sensors (LPS) are self-contained 4-20 mA vibration transmitters designed to integrate directly with Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS). These sensors enable plant personnel to continuously monitor overall vibration levels, trend machine health, and correlate vibration data with operating conditions. This capability facilitates effective Condition Based Maintenance (CBM) programs, allowing for proactive scheduling of maintenance tasks and preventing machine failures, even in the absence of dedicated vibration analysis technicians. LPS transducers offer a convenient, reliable, and cost-effective solution for machinery condition monitoring, providing a direct 4-20 mA signal proportional to average vibration, thereby aiding in operational efficiency and cost reduction.
