Wilcoxon LPS Series 4-20 mA Vibration Transducers
Product Overview
Wilcoxon LPS Series loop-powered vibration transmitters are designed to integrate directly with Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS). These self-contained transducers provide a 4-20 mA signal that correlates to the average vibration of monitored machinery, enabling continuous monitoring, trending of overall vibration data, and correlation with plant operating conditions. This facilitates a Condition Based Maintenance (CBM) program by providing plant personnel with an indication of overall vibration levels, aiding in the scheduling of maintenance tasks and identifying machinery with severe vibration issues, even in the absence of dedicated vibration analysis technicians. They are a convenient, reliable, and cost-effective option for machine health monitoring, helping to prevent failures and reduce outages.

Technical Specifications
| Category | Specification | Details |
|---|---|---|
| Measurement Basis | Primary Measurement | Velocity (most common for external case monitoring) |
| Available Measurements | Velocity or Acceleration | |
| Output Signal Calibration | Peak, True Peak, or RMS (for broadband); Peak or RMS (for frequency banded) | |
| Output Types | Standard 4-20 mA | Correlates to overall vibration |
| Dual Output | 4-20 mA vibration + Temperature | |
| Dual Output | 4-20 mA vibration + Dynamic signal (100 mV/g or 100 mV/ips) | |

| Equipment Groups (ISO 10816-3) | Group 1 (Power >300 kW), Group 2 (Power 15-300 kW), Group 3 (Pumps, separate driver >15 kW), Group 4 (Pumps, integrated driver >15 kW) | |
| Evaluation Zones (ISO 10816-3) | Zone A | Normal for newly commissioned machines |
| Zone B | Acceptable for unrestricted long-term operation | |
| Zone C | Unsatisfactory for long-term continuous operation | |
| Zone D | Potentially damaging severity | |

| Explosion Proof (EX) | CSA Class 1, 2, 3 Div 1, 2 GRPS A-G T3C; ATEX EEx d IIC T3 / EEx nA IIC T3. Model numbers end in -EX. | |
| Model Numbering System (Partial) | Base Models | PC420 (top exit), PCC421 (side exit, small), PC423 (side exit, integral cable), PC425 (side exit, temp sensor), PC427 (side exit, temp sensor, integral cable) |
| Measurement Type | A (Acceleration), V (Velocity) | |
| Output Calibration | AP (Accel Peak), AR (Accel RMS), ATP (Accel True Peak), VP (Vel Peak), VR (Vel RMS), VTP (Vel True Peak) | |
| Ranges | -05, -10, -20, -30, -50 (specific units for g or ips) | |
| Cabling/Connection Options | Examples: R6, M12-4, J9T2A, J10, J9T4, J9T4A, J95, DA (Dynamic Accel), DV (Dynamic Vel), IS, EX | Integral cable standard length is 16'. Alternative lengths available upon request. |
