Description
Option 05 (50 mm unthreaded length) and Option 12 (120 mm overall case length) specify this unarmored, metric-threaded 3300 XL 8 mm proximity probe configuration — 330103-05-12-10-01-00. This non-contacting eddy-current sensor belongs to the Bently Nevada 3300 XL series and is engineered for shaft vibration, axial position, and speed measurements on rotating machinery. Because it has an unarmored standard FEP cable with a 1.0-meter total length (Option 10) and is equipped with a ClickLoc connector with an integrated connector protector (Option 01), this configuration is ideal for installations inside machinery housings where physical shielding is already present and environmental connector isolation is needed.
Unlike variants using the 05 agency approval option, this model represents the Option 00 configuration, meaning it does not carry hazardous area certifications like ATEX, IECEx, or CSA, making it a cost-effective choice for general-purpose or non-hazardous plant areas. Its M10 x 1 metric thread allows direct mounting into metric threaded holes without the need for thread adapters. The probe utilizes polyphenylene sulfide (PPS) for the tip encapsulation, providing robust chemical resistance and physical durability inside oil-rich machine casings.
Features
- Metric Thread Type: M10 x 1 threaded steel case without armor.
- Unthreaded Length: 50 mm unthreaded length (Option 05) allows adjustable mounting depth.
- Overall Case Length: 120 mm overall case length (Option 12) for deep thread engagement.
- Total Cable Length: 1.0 meter (3.3 feet) total probe length (Option 10).
- Connector Protector: Equipped with a miniature male coaxial ClickLoc connector and a pre-installed connector protector (Option 01).
- No Agency Approvals: Option 00 configuration for non-hazardous and general-purpose industrial environments.
- Durable Construction: Encapsulated PPS tip with AISI 303/304 stainless steel case.
Applications
Used primarily for vibration and displacement monitoring on industrial rotating machinery including:
- Steam and gas turbines
- Centrifugal compressors and pumps
- Electric motors and generators
- Industrial gearboxes and machinery trains
- General-purpose rotating machinery shaft relative vibration measurements

Installation Guidelines
Ensure correct mechanical installation of the metric proximity probe to secure accurate measurements:
- Verify that the unthreaded length (50 mm) is fully compatible with the mounting bracket or machine housing depth.
- Tighten the probe case to a maximum recommended torque of 22.6 N-m (200 in-lbf) during installation.
- Ensure the minimum bend radius of 25.4 mm (1.0 in) is maintained for the probe cable to avoid insulation damage or conductor fatigue.
- The connection between the probe cable and extension cable must be clean, dry, and secure. Use the pre-installed connector protector (Option 01) to seal the mating point from moisture and contaminant ingress.
- Ensure proper electrical isolation by preventing probe cables from contacting sharp edges or vibrating structures within the machine.
Compliance and Certifications
This specific variant (330103-05-12-10-01-00) is configured with Option 00 (no agency approvals required). It is designed for use in non-hazardous, general-purpose industrial locations. For application requirements inside hazardous areas, select alternative variants ending in -05 (ATEX, IECEx, CSA approved) or suffix variants ending in -CN (NEPSI, CCC certified).
