Bently Nevada 330704-000-080-10-01-00 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 080 (80 mm case length), and Option 01 (ClickLoc connector with protector) specify this armored metric thread configuration — 330704-000-080-10-01-00, a 3300 XL 11 mm proximity probe used for shaft vibration, axial position, and speed measurements on rotating machinery.

This configuration incorporates an integral 1.0-meter coaxial cable with flexible stainless steel armor, shielded by an outer FEP jacket to resist chemical exposure and physical wear. Unlike unarmored models (such as the 330703 base model), this armored variant provides mechanical protection for harsh industrial areas. The M14 x 1.5 metric thread allows direct mounting through machine casings, while the pre-installed ClickLoc connector protector seals the connection against oil and humidity ingress.

Features

• M14 x 1.5 metric thread with standard 80 mm case length (Option 080) and 0 mm unthreaded length (Option 000).
• AISI 302 stainless steel armor with protective FEP jacket provides mechanical shielding for the triaxial cable.
• ClickLoc miniature coaxial male connector pre-installed with a fluorosilicone connector protector (Option 01).
• 1.0 meter (3.3 feet) total integral cable length (Option 10) matched for 5-meter or 9-meter system configurations.
• Polyphenylene sulfide (PPS) probe tip material for chemical and heat resistance in turbine oil environments.
• 3.94 V/mm (100 mV/mil) scale factor when paired with a matching 3300 XL 11 mm Proximitor Sensor.
• 4.0 mm (160 mils) linear measurement range starting at approximately 0.5 mm (20 mils) from the target.

Applications

• Turbine and compressor shaft vibration monitoring
• Rotor axial (thrust) position and differential expansion measurements
• Rod position and rod drop monitoring in reciprocating compressors
• Speed measurement and Keyphasor phase reference signal generation
• Harsh industrial environments requiring armored cabling and connector seal protection

Installation Guidelines

• Ensure correct mounting torque: M14 x 1.5 thread cases have a maximum torque rating of 63.3 N-m (560 in-lb) and a recommended installation torque of 21.1 N-m (187 in-lb).
• Do not exceed the maximum thread engagement length of 21 mm to prevent binding during installation.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) for both armored and unarmored portions.
• Verify the total system length: The probe length plus extension cable length must equal the Proximitor Sensor system length (e.g., 5.0 m or 9.0 m system).
• Use the pre-installed ClickLoc connector protector to seal the connection; silicone tape is not recommended in environments exposed to turbine oil.
