ï¸ Industrial Application Solutions
Power Generation Turbines: Monitor bearing housing vibration on steam and gas turbines where velocity measurements complement proximity probe displacement data. The 10 Hz low-frequency response captures subsynchronous instabilities while 1 kHz bandwidth detects gear mesh and blade pass frequencies.
Petrochemical Pumps & Compressors: Install on centrifugal pump casings and reciprocating compressor frames to detect cavitation, impeller rub, valve impacts, and foundation resonances. The 4-20 mA output integrates directly with DCS alarm systems for automated shutdown protection.
Mining Conveyors & Crushers: Track belt idler bearing degradation and crusher eccentric shaft conditions in dusty, high-vibration environments. The sealed 316L construction withstands mineral processing plant atmospheres.
Marine Propulsion Systems: Measure main engine and auxiliary machinery vibration aboard vessels where salt spray and temperature cycling demand corrosion-resistant sensors with wide thermal range.
HVAC & Building Systems: Monitor large chiller compressors, cooling tower fans, and air handling unit motors where velocity-based condition monitoring prevents costly emergency repairs.
Engineering Advantages & Differentiation
- RMS Velocity Output: Directly measures vibration severity per ISO 10816 standards without integration or differentiation
- Self-Powered Design: Requires only 4-20 mA loop power — no separate excitation voltage needed
- Ground Loop Immunity: High electrical isolation prevents measurement errors in electrically noisy industrial environments
- Magnetic Base Compatible: Can be used with magnetic mounting for temporary measurements (roll-on technique required to prevent spike damage)
- Maintenance-Free Operation: Solid-state electronics with no moving parts for decades of reliable service
Installation Best Practices
- Surface Preparation: Machine mounting surface flat to within 0.025mm (0.001″) for optimal coupling
- Stud Mounting: Use recommended torque (4-7 N ·m) with thin layer of high-temperature anti-seize compound
- Location Selection: Mount on bearing housing or structural point with direct load path to bearing
- Orientation: Install in radial direction (horizontal or vertical) based on expected vibration mode
- Cable Routing: Secure MIL-C-5015 connector and route cable away from high-temperature surfaces
- Magnetic Base Usage: If using magnetic mount, ROLL the base onto surface — never snap or drop to prevent electronics damage
System Integration & Compatibility
The 4-20 mA current loop output connects to:
- Bently Nevada 3500 Series monitoring racks via 3500/25 Keyphasor modules
- Distributed control systems (DCS) with analog input cards
- Programmable logic controllers (PLC) with 4-20 mA input modules
- Portable vibration analyzers and data collectors
- Chart recorders and paperless recorders for trend documentation
