Specific Application

• Radial vibration and axial position monitoring on fluid-film bearing machines using metric housing standards.
• Keyphasor reference and speed measurements where mounting space accommodates an unarmored M10x1 case thread.
• Machinery protection deployment complying with API 670 standard parameters for mechanical configuration and thermal stability.

System Compatibility & Alternatives

• System Compatibility:
  Fully compatible with Bently Nevada 3300 XL Proximitor Sensors (such as 330180) and 3300 XL Standard Extension Cables (such as 330130). It is physically and electrically interchangeable with standard non-XL 3300 series metric 5mm and 8mm transducer system configurations.
• Alternative Model & Differences:
  The explicit alternative mechanical configuration is catalog number 330104-00-05-10-02-00.
• The Difference: The 330103-00-05-10-02-00 is constructed completely "without armor" for clean, unobstructed conduit runs. The 330104 variant incorporates flexible stainless steel armor with an FEP outer jacket surrounding the 75Ω triaxial probe cable, providing increased mechanical protection against physical abrasion, sharp machinery edges, and impact cutting inside harsh factory spaces.

Installation & Troubleshooting FAQ

Q1: What is the correct tightening torque for installing the 330103 metric forward-mounted probe case?

A: For standard metric M10x1 threads, the maximum rated mounting case torque is 33.9 N•m (300 in•lbf), while the recommended field installation torque is 11.2 N•m (100 in•lbf). If you are clamping or securing into the first three threads of the housing interface, the torque limits drop to a maximum of 22.6 N•m (200 in•lbf) and a recommended value of 7.5 N•m (66 in•lbf) to mitigate thread stripping or binding.

Q2: What is the physical meaning of the '00' and '05' option codes for this specific metric probe?

A: The '00' unthreaded length option specifies that the entire 50mm case length is fully threaded (0mm unthreaded section). The '05' case length option defines a total structural case length of 50mm. Ordering an unthreaded length code requires the configuration to be at least 20mm shorter than the assigned metric case length option to ensure structural structural integrity.

Q3: How tightly should the coaxial ClickLoc connectors be fastened during system assembly?

A: The gold-plated brass ClickLoc miniature connectors connecting the probe lead to the extension cable are designed for finger-tight installation only. Rotate the connection components together until you hear or feel an audible "click", which indicates that the internal locking mechanism is securely latched. Do not use pliers or specialized wrenches on these gold connectors, as excessive torque will deform the gold interfaces.

Q4: Can this specific 1.0-meter unarmored probe be connected directly to a Proximitor sensor without an extension cable?

A: Yes, it can, but only if you use a 1-meter total length Proximitor sensor configuration. Transducer systems require their combined electrical length (probe plus extension cable) to precisely match the total calibrated length rating of the Proximitor sensor—typically 5.0 meters or 9.0 meters. Because this probe has a 1.0-meter integral cable, it can bypass the extension cable only when paired directly with a 1.0-meter rated sensor.
