Bently Nevada 330704-000-100-10-02-00 3300 XL 11 mm Proximity Probe

Description

Fully threaded M14 x 1.5 metric armor-clad probe body (Option 330704) with a 100 mm case length (Option 100) and 0 mm unthreaded length (Option 000) specifies the 330704-000-100-10-02-00 3300 XL 11 mm Proximity Probe. This non-contacting eddy-current sensor features a 1.0-meter total cable length (Option 10) terminated in a miniature ClickLoc coaxial connector without a connector protector (Option 02), configured without hazardous area approvals (Option 00).

This specific configuration incorporates robust stainless steel armor to shield the standard FEP-insulated coaxial cable from mechanical wear and abrasive environments. Designed to operate as a part of a 3300 XL 11 mm Proximity Transducer System, this 11 mm tip probe offers a wide 4.0 mm (160 mil) linear range and output of 3.94 V/mm (100 mV/mil). It is fully compatible with the 330780 Proximitor Sensor and 330730 extension cable, providing non-contacting shaft displacement and axial position monitoring under harsh industrial conditions. Utilizing standard cable (Option 02) instead of FluidLoc ensures cost-effective performance in non-pressurized fluid environments, and the M14 x 1.5 threaded armored casing delivers high mechanical torque capability.

Features

• M14 x 1.5 Threaded Case with Stainless Steel Armor: Protective AISI 302 stainless steel armor over FEP jacket defends the coaxial cable from abrasive contact and mechanical damage.
• 0 mm Unthreaded Length (Option 000): Fully threaded M14 x 1.5 metric case profile ensures maximal mounting depth adjustments.
• 100 mm Case Length (Option 100): Direct threaded engagement length of 100 mm for installations requiring extended reach or deep mounting brackets.
• 1.0 Meter Total Length (Option 10): Convenient 1-meter integrated cable length matches 5.0 m or 9.0 m overall system configurations when combined with an extension cable.
• Miniature ClickLoc Coaxial Connector (Option 02): Gold-plated brass ClickLoc connector ensures secure, low-loss electrical coupling without the added bulk of an external connector protector.
• 11 mm Probe Tip Diameter: Large 11 mm tip design provides an extended 4.0 mm linear range, making it ideal for tracking large thermal expansions or axial shifts.
• No Agency Approvals (Option 00): Cost-optimized variant for non-hazardous locations and standard industrial environments.

Applications

• Steam and gas turbine rotor axial (thrust) position and axial displacement monitoring
• Ramp differential expansion measurements on industrial steam turbines
• Rod drop or piston rod position tracking on large reciprocating compressors
• Phase reference (Keyphasor) signal generation and zero speed / tachometer measurements
• Compressor and high-power fan shaft vibration analysis in utility and process industries

Installation Guidelines

• Grounding and Shielding: Ensure proper isolation and shielding of cable connections to prevent ground loops and external electromagnetic interference.
• Thread Torque: Tighten M14 x 1.5 probe case to a maximum of 63.3 N-m (recommended torque is 21.1 N-m).
• Connection Guide: Hand-tighten the miniature coaxial ClickLoc connector (maximum torque 0.565 N-m).
• Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) for armored probe cable routing to avoid physical damage to the coaxial core.
• Gap Setting: Target a recommended gap of 2.5 mm (100 mils) corresponding to approximately -10 Vdc output voltage during normal operation.
