Installation & Setup Guidance
Mount the Bently Nevada 330191-00-33-05-00 using the 3/8-24 UNF thread. Ensure thread engagement does not exceed 0.563 inches. Use the provided Viton O-ring to seal differential pressure between probe tip and case. Tighten connectors to 0.565 N•m maximum. For cables, use only BN extension cables to meet entity parameters. One-meter systems do not require an extension cable. The patented CableLoc design provides 330 N pull strength for secure cable attachment.
Maintenance & Reliability
The Bently Nevada 330191-00-33-05-00 probe features TipLoc molding for a robust bond between tip and body. The thicker encapsulation of the 8 mm probe coil in PPS plastic enhances durability. For environments with oil leakage, order the optional FluidLoc cable option. The probe can operate in ambient temperatures from -55°C up to +232°C (T1 rating). Inspect the O-ring and connectors periodically for wear. Avoid exceeding the maximum connector torque to prevent damage.
Selection Guide
When ordering the Bently Nevada 330191-00-33-05-00, verify the total probe length: this unit is 0.5 meter (1.6 feet). It is supplied without armor and with a nonincendive circuit requirement. For armored versions or different lengths, consult the 3300 XL series options. PLC Source PRO offers this new, original factory-packed unit with a 12-month warranty. Ensure compatibility with your Bently Nevada monitoring system.
