| Model Number | PC421VR-50-IS |
Wilcoxon LPS Series loop-powered 4-20 mA vibration transmitters are designed to seamlessly integrate vibration monitoring data directly into plant control systems like PLCs and DCS. This capability enables continuous monitoring of critical machinery, allowing plant personnel to trend overall vibration levels, correlate data with operating conditions, and proactively schedule maintenance. By providing a direct indication of vibration, these transducers facilitate Condition Based Maintenance (CBM) programs, even in the absence of dedicated vibration analysis technicians. They offer a convenient, reliable, and cost-effective solution for machine health monitoring, helping to prevent costly outages and equipment failures.
| Category | Specification | Details |
|---|---|---|
| Measurement Principle | Velocity or Acceleration | Primary measurement is velocity; acceleration is also available. |
| Output Signal | 4-20 mA loop powered | Directly interfaces with PLC/DCS. |
| Output Calibration Options | Peak, True Peak, RMS | Available for broadband transducers. Frequency banded versions offer Peak or RMS. |
| Frequency Banding Options | Low Frequency (3 Hz - 40 Hz) | Example Model: PC420VP-10-B3041. Focuses on frequencies associated with balance and alignment issues. |
| Frequency Banding Options | High Frequency (300 Hz - 2,000 Hz) | Example Model: PC420AR-10-3223. Focuses on frequencies associated with pump cavitation. |
| Dual Output Options | 4-20 mA + Dynamic Signal | Dynamic signal can be 100 mV/g (acceleration) or 100 mV/ips (velocity). Useful for portable spectrum analyzers. |
| Dual Output Options | 4-20 mA + Temperature | For temperature-sensitive operations. |
| Full Scale Selection | Fixed, User Not Adjustable | Selected at time of order based on machine's normal vibration levels and manufacturer/ISO limits. Normal vibration should be 10-20% of full scale. |
| ISO 10816 Guidance | Part 3: Industrial machines (>15 kW, 120-15,000 RPM) | Provides guidance for determining vibration limits and transducer selection based on equipment groups and rotor modes (rigid/flexible). |
| Equipment Groups (ISO 10816-3) | Group 1 | Large machines (>300 kW / ~400 HP), shaft height >= 315 mm, sleeve bearings. |
| Equipment Groups (ISO 10816-3) | Group 2 | Medium machines (15-300 kW / ~20-400 HP), shaft height 160-315 mm, rolling element bearings, speed > 600 RPM. |
| Equipment Groups (ISO 10816-3) | Group 3 | Pumps with separate driver (>15 kW). |
| Equipment Groups (ISO 10816-3) | Group 4 | Pumps with integrated driver (>15 kW). |
| Evaluation Zones (ISO 10816-3) | Zone A | Vibration of newly commissioned machines. |
| Evaluation Zones (ISO 10816-3) | Zone B | Acceptable for unrestricted long-term operation. |
| Evaluation Zones (ISO 10816-3) | Zone C | Unsatisfactory for long-term continuous operation; limited operation until remedial action. |
| Evaluation Zones (ISO 10816-3) | Zone D | Severity may cause damage to the machine. |
| Hazardous Area Ratings | Intrinsically Safe (IS) | CSA Class 1, Div 1, GRPS A, B, C, D T3C; ATEX EEx ia IIC T3. Models end in -IS. |
| Hazardous Area Ratings | Explosion Proof (EX) | CSA Class 1, 2, 3 Div 1, 2 GRPS A-G T3C; ATEX EEx d IIC T3 / EEx nA IIC T3. Models end in -EX. |
| Connector Options | Top Exit, Side Exit, Integral Cable | Various configurations including small size and with temperature sensors. |
| Cable Options | Standard 16' integral cable | Alternative lengths available upon request (may incur additional charges). |
