Bently Nevada 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe

Description

330709-050-120-10-02-00: This unarmored M16 x 1.5 metric thread 3300 XL 11 mm proximity probe configuration features a 50 mm unthreaded length, a 120 mm overall case length, a 1.0 m total length, and a standard miniature ClickLoc coaxial connector.

Unlike variants equipped with stainless steel protective armor (such as model 330710) or those containing FluidLoc cable options (Option 11 or 12) for fluid migration resistance, this configuration relies on standard coaxial cabling and an unarmored construction. The 11 mm tip diameter offers an extended linear range compared to 8 mm transducer systems, making it appropriate for machinery position measurements where greater range is needed.

Features

• Metric thread design: Features M16 x 1.5 mounting thread on an unarmored probe body (model 330709).
• 50 mm unthreaded length (Option 050) and 120 mm overall case length (Option 120) for targeted physical spacing.
• 1.0 m total length (Option 10) matching shorter proximity probe lead requirements.
• Standard coaxial ClickLoc miniature connector (Option 02) without a connector protector.
• Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case for process environment isolation.
• Extended linear measurement range of 4.0 mm (160 mils) for increased displacement sensitivity.

Applications

• Thrust (axial) position measurements on steam turbines.
• Ramp differential expansion measurements in power generation systems.
• Rod position and rod drop monitoring on reciprocating compressors.
• Tachometer, zero speed, and phase reference (Keyphasor) signal generation.
• Radial vibration and position monitoring on fluid film bearing machinery.

Installation Guidelines

• Probe Case Torque: When installing the M16 x 1.5 probe, do not exceed the maximum rated torque of 63.3 N-m (560 in-lb). The recommended mounting torque is 21.1 N-m (187 in-lb).
• Thread Engagement Limits: The maximum length of thread engagement for M16 x 1.5 cases is 24 mm. Exceeding this depth can lead to binding or damage.
• Connector Handling: Connect the miniature coaxial ClickLoc connector finger tight. The maximum allowable connector-to-connector torque is 0.565 N-m (5 in-lb).
• Cable Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) along the probe cable and any extension cable routing to prevent internal conductor damage.
• Protection from Fluids: When exposing the probe connection to turbine oil or industrial fluids, use appropriate protection or connector protectors to prevent contamination. Avoid silicone tape.
