Bently Nevada 330701-00-10-90-12-05 Proximity Probe
Product Introduction 330701-00-10-90-12-05
The Bently Nevada 330701-00-10-90-12-05 is a high-performance sensor from the renowned 3300 XL series. This 11 mm proximity probe delivers precise, non-contact measurements of shaft vibration and position. It is an essential component for predictive maintenance and machinery protection in critical rotating equipment.
Furthermore, this model is specifically configured for demanding applications. It features the robust 1/2-20 UNF mounting thread and a total length of 9.0 meters (29.5 feet). The inclusion of the FluidLoc cable and miniature coaxial ClickLoc connector ensures a secure and reliable installation, which is crucial for continuous operation.
Technical Specifications 330701-00-10-90-12-05
The Bently Nevada 330701-00-10-90-12-05 sensor is built with a Polyphenylene sulfide (PPS) probe tip and an AISI 304 stainless steel (SST) probe case. Its 75 Ω triaxial cable uses fluoroethylene propylene (FEP) insulation, providing excellent dielectric strength. This model offers a DC resistance from the center conductor to the outer conductor of 8.5 ± 1.1 ohms.
Specifically, the probe's electrical characteristics are optimized for the 3300 XL monitoring system. The unthreaded length is 0.0 inches, and the overall case length is 1.0 inch. Additionally, the 330701-00-10-90-12-05 carries multiple agency approvals, making it suitable for global installations. The operating and storage temperature range for this proximity probe is from -51°C to +177°C.
Mechanical & Environmental Parameters
The mechanical design of the Bently Nevada 330701-00-10-90-12-05 is tailored for rugged reliability. The probe case thread is 1/2-20 UNF, with a maximum thread engagement of 0.750 inches. For installation, the recommended torque for the probe case is 15.2 N•m (133 in•lb), while the maximum rated torque is 45.2 N•m.
Moreover, the connector-to-connector joint should be finger-tight, with a maximum torque of 0.565 N•m (5 in•lb). The cable has a minimum bend radius of 25.4 mm (1.0 inch), even when equipped with stainless steel armor. Meanwhile, the probe is designed to seal differential pressure between the tip and case using a Viton O-ring. However, it is important to note that probes are not pressure tested prior to shipment.
Installation Guidelines
Proper installation of the Bently Nevada 330701-00-10-90-12-05 ensures accurate and long-lasting performance. First, always ensure the mounting surface is clean and the threads are undamaged before installation. Next, apply the recommended torque of 15.2 N•m to secure the probe case, avoiding overtightening to prevent thread damage.
Additionally, when routing the 9-meter FEP cable, maintain a bend radius greater than 25.4 mm to protect the internal conductors. For the ClickLoc connector, finger-tight torque is sufficient for a secure connection. Finally, avoid exposing the probe to temperatures below -34°C during storage or operation, as this may cause premature failure of the pressure seal.

Frequently Asked Questions (FAQ)
Q1: What is the total cable length of the Bently Nevada 330701-00-10-90-12-05?
A1: This model comes with a total probe length of 9.0 meters (approximately 29.5 feet), as indicated by the "90" option code in the product number.
Q2: What is the difference between the 330701-00-10-90-12-05 and other 3300 XL probes?
A2: The key differences lie in its configuration: it has a 1/2-20 UNF thread, no armor, a 1.0-inch overall case length, a 9.0-meter cable, a miniature ClickLoc connector with FluidLoc cable, and multiple agency approvals.
Q3: Can this proximity probe be used in high-temperature environments?
A3: Yes, the Bently Nevada 330701-00-10-90-12-05 operates reliably from -51°C to +177°C. However, prolonged exposure below -34°C should be avoided to protect the pressure seal.
Q4: What is the recommended torque for installing this probe?
A4: The recommended installation torque for the 1/2-20 UNF probe case is 15.2 N•m (133 in•lb). The maximum rated torque is 45.2 N•m.
Q5: Is the Bently Nevada 330701-00-10-90-12-05 pressure tested before shipping?
A5: No, these probes are not pressure tested prior to shipment. If your application requires a pressure seal test, please contact the custom design department for special arrangements.
