Product Overview: Bently Nevada 330180-12-BR
From a maintenance engineer's perspective, the Bently Nevada 330180-12-BR 3300 XL Proximitor Sensor delivers engineering-grade precision for non-contacting displacement measurement. This unit provides a 1.0 meter (3.3 feet) system length and ships without mounting hardware. Its A308 aluminum housing and gold-plated brass or beryllium copper connector ensure robust field performance. The sensor accepts one 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable, making it a precise interface for critical turbomachinery monitoring.
Key Specifications and Performance
- Input: Requires -17.5 Vdc to -26 Vdc with non-incendive circuits at 12 mA maximum.
- Isolation: Mounting base provides electrical isolation, eliminating separate isolator plates.
- Output Resistance: 50 Ω for stable signal transmission.
- Sensitivity: Less than 2 mV output change per volt input change.
- Operating Temperature: -52°C to +100°C (-62°F to +212°F).
- Weight: 246 g (8.67 oz).
- Approval: BR=Country Specific agency approval.
Notably, the SpringLoc terminal strips require no special tools and resist loosening better than screw-type clamps. This reduces maintenance intervals and enhances long-term reliability.
Installation and Maintenance Insights
Installation is straightforward: the sensor supports high-density DIN-rail or traditional 4-hole panel mounting. Because the base provides electrical isolation, you avoid separate isolator plates. The 3300 XL design is highly immune to radio frequency interference, so you can install it in fiberglass housings without shielded conduit. For maintenance, inspect terminal connections periodically and verify supply voltage stays within -17.5 Vdc to -26 Vdc. Operation above -23.5 Vdc may reduce linear range. Storage temperature ranges from -52°C to +105°C (-62°F to +221°F).
