Performance and Reliability
The 330905-00-10-10-02-00 delivers accurate measurements with a deviation from best-fit straight line (DSL) of less than ±0.06 mm (±2.3 mils). Its improved chemical resistance compared to the earlier 3300 RAM probe allows use in demanding process environments. The probe is mechanically and electrically interchangeable with previous 3300 RAM models, simplifying upgrades.
Installation and Setup
For optimal performance, mount the probe with finger-tight torque (maximum 0.56 N•m). The recommended gap setting is 1.0 mm (40 mils). Ensure the target surface is flat and at least 13 mm (0.5 in) in diameter for accurate readings. For shaft diameters smaller than 13 mm, reduce the gap to minimize scale factor changes.
Compatibility and Integration
This Bently Nevada 330905-00-10-10-02-00 probe works with the 3300 XL NSv Proximitor Sensor and supports field wiring up to 305 meters (1,000 feet). Use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors. The probe is compatible with Bently Nevada monitoring systems that accept 3300 NSv inputs.
Maintenance and Longevity
Routine inspection of the probe cable and connector is recommended to prevent signal degradation. The probe's rugged construction—stainless steel case and PPS tip—ensures long service life in harsh environments. Operating and storage temperature ranges of -52°C to +177°C allow use in extreme conditions.
Selection Guide and Purchasing Advice
When ordering, verify the unthreaded length (00 mm), overall case length (100 mm), total length (1.0 m), and connector type (miniature coaxial ClickLoc). This model does not require agency approval.
