- Extension sleeve included to adjust mounting height and avoid mechanical interference
- Feraloy alloy base offers high mechanical rigidity to preserve accurate vibration transmission
- Certified for use in classified hazardous areas on turbines and compressors
- Designed for long-term outdoor and turbine compartment service
Installation & Test Notes
- Select flat or dome cover and assemble the kit components according to machine layout.
- Mount the base rigidly on the machine casing; ensure clean, flat contact surface for vibration transfer.
- Install accelerometer inside housing and route sensor cable through the NPT port, fit cable gland properly.
- Assemble gasket, O-ring and cover, evenly torque fasteners to maintain full environmental sealing.
- Connect accelerometer cable to 3500 monitor module, verify vibration signal reading after power-up.
- Check seal integrity periodically; replace neoprene gaskets/O-rings if cracked, hardened or leaking.
- Inspect housing for corrosion, loose bolts or mechanical damage after machine overhaul.
Application
Vibration monitoring on steam turbines, gas turbines, centrifugal compressors, large fans and pumps in power plants, oil & gas refineries and petrochemical plants. Protects accelerometers in high-temperature, humid, oily or explosive hazardous zones for Bently Nevada 3500 machinery protection systems.
FAQ
Q: Which accelerometers fit the 43217-02 mounting kit? A: It is designed for Bently Nevada 330400 and 330425 series accelerometer vibration sensors.
Q: What is the difference between flat cover and dome cover? A: Flat cover is the standard option; dome cover provides extra internal clearance for sensor connector in tight mounting spaces.
