Industrial Applications
Pumps & Motors
Monitor vibration in centrifugal pumps, positive displacement pumps, and electric motors. Early detection of bearing wear, unbalance, and misalignment prevents costly downtime.
Fans & Blowers
Track vibration levels in induced draft fans, forced draft fans, and process blowers. Prevent blade damage and bearing failures in HVAC and industrial ventilation systems.
Compressors
Measure vibration in reciprocating compressors, screw compressors, and rotary compressors. Detect valve failures, bearing wear, and foundation issues.
Gearboxes & Reducers
Monitor gearbox vibration to identify gear tooth wear, bearing defects, and lubrication problems. Extend gearbox life through predictive maintenance.
Installation & Configuration
Mounting Options
- DIN Rail Mount – Snap module onto standard 35mm DIN rail in control cabinet
- Panel Mount – Use mounting brackets for direct panel installation
Configuration Steps
- Connect accelerometer or velocity sensor to input terminals
- Set measurement range using DIP switches or potentiometer
- Program alarm setpoints (Alert and Danger levels)
- Connect 4-20mA output to DCS/PLC analog input
- Wire relay contacts to machinery shutdown system
- Apply 24V DC power and verify LED indicators
- Calibrate using vibration calibrator or known vibration source
Alarm Configuration
Two-Stage Alarm System
- Alert Level: Early warning of elevated vibration (typically 70% of trip level)
- Danger Level: Critical alarm triggers machinery shutdown
Typical Setpoints (ISO 10816)
| Machine Type | Alert (mm/s RMS) | Danger (mm/s RMS) |
|---|---|---|
| Small machines (<15 kW) | 4.5 | 7.1 |
| Medium machines (15-75 kW) | 7.1 | 11.2 |
| Large machines (>75 kW) | 11.2 | 18.0 |

FAQ
Q: What type of sensor should I use?
A: Accelerometers for general purpose (10 Hz-1 kHz). Velocity sensors for low-frequency applications (10-1000 Hz).
Q: Can I use this for API 670 applications?
A: No, this is a general purpose monitor. Use 3300 XL or 3500 series for API 670 compliance.
Q: How often should I recalibrate?
A: Annual calibration verification recommended. Full recalibration every 3-5 years.
