7402-080-00 - Eddy Current Vibration Probe - 80mV/mm/s IP67 Stainless Industrial Sensor

1. Machinery Health Monitoring Transmitter Overview​

The ProvibTech 7402-080-00 is a rugged vibration transmitter engineered for continuous condition monitoring of critical industrial equipment. Featuring an ​integrated IEPE accelerometer​ and ​4-20mA output, this device measures velocity RMS (0-80mm/s) with ​​±1% accuracy​ across a ​10Hz–1kHz frequency range. Its ​anodized aluminum housing​ provides ​IP66 protection​ against dust and water jets, while the ​DIN-rail mounting​ enables seamless integration into control panels. Operating across ​​-40°C to +85°C​ with ​ATEX/IECEx Zone 22 certification, it delivers ISO 10816-compliant vibration data for predictive maintenance of pumps, motors, fans, and gearboxes in power generation, oil & gas, and manufacturing facilities. The transmitter's loop-powered design simplifies installation while providing real-time machinery health insights.

​2. Key Technical Specifications​

This vibration transmitter delivers velocity RMS measurements from 0-80mm/s with ±1% full-scale accuracy. Electrical specifications include 2-wire 4-20mA output (loop-powered at 18-30V DC), 500Ω maximum loop resistance, and reverse polarity protection. The integrated IEPE accelerometer offers 100mV/g sensitivity with 10Hz high-pass filtering. Environmental resilience includes IP66 protection (IEC 60529), -40°C to +85°C operating temperature, and 10g vibration resistance (10-150Hz per IEC 60068-2-6). Mechanical construction features a compact 22.5mm DIN-rail module with screw terminals for 0.2-2.5mm² wires. Safety certifications cover ATEX II 3G Ex ec IIC T85°C Gc and IECEx Ex ec IIC T85°C Gc for Zone 22 hazardous areas.

​3. Industrial Predictive Maintenance Applications​

This transmitter serves critical roles in asset health monitoring:

• ​Power Plant Turbines: Bearing condition monitoring per API 670 standards
• ​Offshore Pumping Stations: Cavitation detection in Zone 22 environments
• ​Mining Conveyor Drives: Gearbox health assessment in dusty conditions
• ​HVAC Cooling Towers: Fan imbalance detection in commercial buildings
• ​Refinery Centrifugal Compressors: Vibration trending for rotor imbalance
• ​Water Treatment Plants: Pump bearing degradation tracking
• ​Paper Machine Drives: Roller bearing fault detection
• ​Marine Engine Rooms: Auxiliary equipment vibration surveillance
  Its 80mm/s velocity range accommodates severe fault conditions in heavy machinery while maintaining measurement integrity during transient events like pump cavitation or gear tooth failures.

​5. Signal Processing and Safety Functions​

​Measurement Workflow:

1. ​Vibration Sensing:
   • Piezoelectric accelerometer generates charge proportional to acceleration
2. ​Signal Conditioning:
   • 10Hz high-pass filter removes low-frequency artifacts
   • Integration to velocity (mm/s RMS)
3. ​Output Scaling:
   • 4mA = 0mm/s RMS, 20mA = 80mm/s RMS
   • Linear relationship: 0.2mA/mm/s

​Alarm Management:

• Configurable thresholds via DIP switches:
  • Warning level: 16mA (64mm/s)
  • Alarm level: 18mA (72mm/s)
• Fail-safe operation:
  Output drops to <3.6mA during sensor fault
  Over-range indication at 21.5mA
