Why Choose This Probe?
Compared to the previous 3300 RAM probe, the 330905-05-13-10-01-05 offers superior side-view characteristics and increased chemical resistance. This makes it ideal for process compressor applications where exposure to aggressive media is common. Its mechanical and electrical compatibility with earlier models allows direct replacement without system redesign.
Installation & Setup
For optimal performance, mount the probe with finger-tight torque, never exceeding 0.56 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm for the cable. When using field wiring, a three-conductor shielded triad cable is recommended, with a maximum length of 305 meters (1,000 feet) to the monitor. Ensure the target surface is flat and at least 13 mm (0.5 in) diameter for recommended operation.
Maintenance & Reliability
The 330905-05-13-10-01-05 requires minimal maintenance due to its robust construction. Regularly inspect the probe tip for debris or damage and verify cable integrity. The Viton O-ring seal provides reliable differential pressure sealing, though probes are not pressure-tested before shipment. For pressure-sensitive applications, contact our custom design department for testing.
Applications
- Vibration monitoring on centrifugal compressors
- Shaft axial position measurement in turbines
- Radial vibration detection on pumps and motors
- Clearance monitoring in gearboxes
Selection Guide
When ordering, verify the unthreaded length (50 mm), overall case length (130 mm), and total length (1.0 m) to match your installation. The miniature coaxial ClickLoc connector with connector protector ensures secure connections. For bulk or custom requirements, PLC Source PRO offers genuine Bently Nevada parts with full warranty.
