Applications
The 330904-00-10-10-02-05 is engineered for vibration monitoring on turbomachinery, compressors, pumps, and motors. Its enhanced chemical resistance makes it particularly suitable for process compressor applications where exposure to corrosive process media is common. The probe also excels in side-view mounting configurations, providing accurate gap measurements even in tight installations.
Installation & Setup
When installing the 330904-00-10-10-02-05, follow these guidelines:
- Use the recommended torque of 5.1 N•m (45 in•lb) for the M8X1 probe case to ensure proper sealing without damaging threads.
- Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent internal damage.
- Set the initial gap to 1.0 mm (40 mils) for optimal linear response.
- For field wiring, use a three-conductor shielded triad cable with cross-section 0.2 to 1.5 mm² (16 to 24 AWG). Maximum cable length between the Proximitor Sensor and monitor is 305 meters (1,000 feet).
Maintenance & Reliability
This proximity probe requires minimal maintenance due to its robust construction. The PPS tip and stainless steel case resist chemical attack and mechanical wear. However, periodic inspection of the cable and connector is recommended to ensure signal integrity. The probe's sealing system uses a Viton O-ring, designed to withstand differential pressure; for pressure-critical applications, consider requesting a pressure seal test from the manufacturer.
Compatibility & Integration
The 330904-00-10-10-02-05 is fully compatible with Bently Nevada's 3300 XL NSv Proximitor Sensor and existing 3300 monitoring systems. It is mechanically and electrically interchangeable with previous 3300 RAM probes, allowing seamless upgrades in legacy installations.
