Product Overview
The Bently Nevada BA42608-03-03 is a rugged IP65 water and dust-resistant velocity transducer housing, engineered for demanding industrial environments. This housing protects velocity sensors while maintaining reliable performance in moisture-prone or dusty settings. With a temperature rating of -29°C to +121°C (-20°F to +250°F), it delivers consistent operation across extreme conditions.
Part of the BA42608 series, this model features a 5/8-in 18 UNF-2B internal mounting thread and a 1/2-in NPT outlet port. The 03 option provides a 1/2-in 14 NPT mounting thread and cap, while the cable exit uses a 1/2-in NPT explosion-proof and cable grip fitting. Weighing just 1.6 kg (3.55 lb) without the sensor or fittings, it is lightweight yet robust.

RoHS Directive 2011/65/EU |
When used with 9200 or 74712 velocity sensors, the sensors must have ATEX or Multiple approvals and an isolator with 5/8-in 18 UNF-2B male threads and a top mount terminal strip.
Key Benefits & Applications
This housing excels in rotating machinery monitoring, including pumps, fans, and compressors, where vibration monitoring is critical. Its IP65 rating ensures protection against water jets and dust ingress, making it ideal for washdown areas or outdoor installations. The neoprene O-ring provides a reliable seal against moisture and corrosion, extending service life in harsh environments.
-
Durability: Resists moisture and corrosion, suitable for humid or corrosive atmospheres.
-
Versatility: Compatible with 9200 and 74712 velocity sensors, subject to approval requirements.
-
Compliance: RoHS compliant, meeting environmental directives.
Installation & Setup
Before installation, verify that the sensor's isolator has 5/8-in 18 UNF-2B male threads and a top mount terminal strip. Ensure the mounting surface is clean and free of debris. Apply appropriate thread sealant to the 1/2-in NPT fittings to prevent leaks. Torque the housing to the recommended specification to avoid damage to the O-ring. For optimal performance, mount the housing in a location that minimizes exposure to excessive vibration or impact beyond the sensor's rated range.
Maintenance & Reliability
Regularly inspect the O-ring for signs of wear or cracking, especially after exposure to extreme temperatures. Check the cable gland and fittings for tightness to maintain the IP65 seal. Clean the exterior with a mild detergent and water; do not submerge the housing. With proper care, this housing provides long-term reliability, reducing downtime and replacement costs.
