Description

Designed to provide robust protection and secure physical installation for industrial vibration sensors, the Bently Nevada 43217-02 is a specialized accelerometer mounting kit. This assembly is engineered to protect critical measurement instrumentation from harsh environmental factors while ensuring reliable mechanical coupling to rotating machinery. The kit features a versatile configuration that includes both flat and dome covers alongside an optional extension, making it highly adaptable for various field installations.

Constructed with durability in mind, the 43217-02 housing base is made of Feraloy, while the covers and extension utilize copper-free aluminum to prevent spark risks and optimize structural integrity. Integrated neoprene gaskets and O-rings provide exceptional environmental sealing against dust, moisture, and chemical contaminants. This kit is specifically tailored to accommodate and protect the 330400 and 330425 Accelerometers, which are widely deployed in critical turbine supervisory instrumentation (TSI) and predictive maintenance systems.

Features

• Dual-Cover Versatility: Package includes both flat and dome covers to support multiple mounting profiles and spatial constraints.
• Rugged Component Materials: Copper-free aluminum covers combined with a heavy-duty Feraloy base ensure long-term mechanical protection in highly demanding industrial areas.
• Environmental Sealing: High-performance neoprene O-rings and gaskets secure the assembly against ingress of fluid, dirt, and industrial particulates.
• Standardized Conduit Entry: Features a 1/2-inch 14 NPT outlet port for seamless integration with standard heavy-walled industrial conduit systems.

Applications

This accelerometer mounting kit is optimized for critical vibration monitoring environments across multiple sectors, including:

• Power generation facilities and steam/gas turbine monitoring.
• Oil and gas extraction platforms and refineries.
• Chemical processing plants.
• Heavy industrial rotating machinery, including large pumps, compressors, and gearboxes.

Technical Specifications

Installation Guidelines

To maintain structural integrity and hazardous area ratings, adhere to the following installation standards:

• Conduit Sealing: Ensure appropriate thread sealant is applied to the 1/2-inch NPT conduit entry to block moisture entry.
• Gasket Alignment: Verify the neoprene O-ring and flat gaskets are seated correctly in their respective grooves before securing the flat or dome cover.
• Torque Requirements: Secure all mounting fasteners uniformly to maintain an even seal without damaging the aluminum components.
• Sensor Mounting: Confirm that the internal accelerometer is securely torque-mounted to the machine surface through the housing base according to the sensor's specific installation manual.
