330104-06-12-10-02-00 is an armored eddy current probe from the Bently Nevada 3300 XL series, with a total length of 1.0 meter (3.3 feet). This model features M10×1 metric threads, 60 mm (approx. 2.36 in) unthreaded length, 120 mm (approx. 4.72 in) overall case length, a standard ClickLoc coaxial connector, and standard FEP‑insulated cable with stainless steel armor. The armor provides excellent crush resistance, tensile strength, and abrasion protection, but the model does not include connector protectors or hazardous area approvals.
The distinguishing features of this probe are its medium unthreaded length (60 mm) and long case length (120 mm). It is designed for applications where the probe tip must extend a moderate distance from a deep mounting hole, such as through moderately thick vessel walls, equipment with deep blind holes, or when the probe tip needs to be positioned away from the mounting flange. The armor provides mechanical protection for the cable in industrial environments where damage is a concern.
With a total length of 1.0 m, this probe is typically used with a 4.0‑meter extension cable (e.g., 330130-040-00-00) and a 5‑meter Proximitor Sensor (e.g., 330180-50-00) to form a complete 5‑meter system (1.0 m probe + 4.0 m extension cable = 5 m system). This configuration is ideal for installations where the Proximitor Sensor is mounted close to the equipment (e.g., in a junction box). This model is a metric‑thread armored probe with a medium unthreaded section and long case.
Model Breakdown: 330104-06-12-10-02-00 Configuration Details
Following Bently Nevada’s part number coding system (refer to datasheet Pages 13-16), the fields in this model number represent the following:
Field | Code | Parameter | Description |
Base Model | 330104
| 3300 XL 8 mm Probe, M10×1 thread, with armor | Metric thread version, cable with stainless steel armor |
Unthreaded Length (A) | 06
| 60 mm | Distance from probe tip to start of thread. Code = mm ÷ 10, so 06 = 60 mm |
Overall Case Length (B) | 12
| 120 mm | Total threaded length. Code = mm ÷ 10, so 12 = 120 mm |
Total Length Option (C) | 10
| 1.0 meter (3.3 ft) | Total probe cable length (including connector); for 5 m systems |
Connector & Cable Option (D) | 02
| Miniature coaxial ClickLoc connector, standard cable | Standard FEP‑insulated cable (with armor), gold‑plated ClickLoc connector, no connector protector |
Agency Approval (E) | 00
| Not required | Standard industrial version for non‑hazardous areas |
Key Configuration Note: This model is a metric thread (M10×1) armored probe with 60 mm unthreaded length and 120 mm case length, specifically designed for applications requiring a medium unthreaded section and a relatively deep mounting hole. The unthreaded length must be at least 20 mm less than the case length (60 < 120‑20 = 100, satisfied). The 1.0 m total length is for 5‑meter systems (paired with a 4.0 m extension cable). The armor provides mechanical protection for environments with crushing, pulling, or abrasion risks. This model does not include connector protectors or hazardous area approvals.
Armor Details
Stainless Steel Armor
The armor layer consists of flexible AISI 302 or 304 stainless steel braid, covered with an FEP outer jacket, providing the following protection:
Crush Resistance: Prevents cable damage from compression during installation or operation
Tensile Strength: Enhances overall cable pull strength for conduit routing
Abrasion Resistance: Prevents insulation damage from friction against metal conduits or equipment edges
Cut Resistance: Protects internal conductors from accidental cuts or sharp object damage
No Connector Protector
This model does not include pre-installed connector protectors, so the connector is exposed to the environment without additional oil or dust sealing. It is suitable for dry, clean environments where the connector will not contact turbine oil, moisture, or dust. If environmental sealing is required, select a version with connector protectors (e.g., 330104-06-12-10-01-00, etc.).
Selection Tip: Armored cable weighs approximately 103 g/m (standard cable is 34 g/m). Consider the tensile load on connectors and probes during installation. The minimum bend radius for armored cable is 25.4 mm (1.0 in), the same as standard cable, but the armor increases stiffness.
Application Scenarios & Selection Guide
330104-06-12-10-02-00 is suitable for the following typical applications:
5‑Meter System + Mechanical Protection + Medium Unthreaded Length & Long Case: Paired with a 4.0 m extension cable and a 5 m Proximitor Sensor to form a complete 5‑meter monitoring system. Ideal for applications where the probe tip must extend 60 mm from the mounting hole and the hole depth is about 120 mm, such as through moderately thick equipment walls or to avoid internal shoulders in the mounting hole.
Thick‑Walled Equipment Vibration Monitoring: For equipment with wall thickness between 60 mm and 120 mm (e.g., large compressor casings, turbine housings), standard probes cannot position the tip close to the target surface. The 60 mm unthreaded length and 120 mm case length satisfy this requirement.
Special Mounting Brackets or Deep Blind Holes: When using non‑standard mounting brackets or when equipment has deep blind holes, this model provides sufficient unthreaded and case lengths.
Conduit Routing + High Mechanical Stress Environments: Armor protects the cable from damage during conduit routing or in high‑vibration environments.
Standard Industrial Environments: No hazardous area approvals – suitable for non‑hazardous, dry, clean installations.
Selection Notes:
Total Length Matching: Probe length + extension cable length = Proximitor Sensor total system length (5 m or 9 m). This 1.0 m probe must be used with a 4.0 m extension cable to form a 5‑meter system.
Thread Matching: The mounting hole must be M10×1 metric thread. Do not mix with 3/8-24 UNF imperial threads.
Unthreaded Length vs. Case Length: The unthreaded length (60 mm) must be at least 20 mm less than the case length (120 mm) – satisfied. Before installation, verify that the mounting hole depth can accommodate the full case length (120 mm), while ensuring that the effective thread engagement does not exceed the recommended value (15 mm for M10). Excess case length will remain outside the mounting hole; be aware of potential space interference.
Effective Thread Engagement: The datasheet maximum recommended thread engagement is 1.5 times the nominal diameter (15 mm for M10). Use lock nuts and washers to limit actual engagement to ≤15 mm. Do not thread the entire 120 mm case into the hole.
Armored Cable Bend Radius: While the minimum bend radius is 25.4 mm, armor increases cable stiffness; allow sufficient clearance when routing.
Weight: Armored cable weighs approx. 103 g/m; consider the tensile load on connectors and probes during long runs.
Connector Protection: If the environment has oil mist or moisture, select a version with connector protectors.
Ambient Temperature: Standard probe is rated to +177°C. For higher temperatures, select an ETR high‑temperature armored probe (330194 series).
Hazardous Area Requirements: If explosive gas atmospheres are present, select the version with hazardous area approvals (e.g., 330104-06-12-10-02-05).
Mechanical Dimensions & Installation
Probe Tip Diameter: 8.0 mm (0.31 in)
Thread Specification: M10×1-6g; recommended lock nut torque: 11.2 N·m (100 in·lbf) (imperial approximate)
Overall Case Length: 120 mm (4.72 in)
Unthreaded Length: 60 mm (2.36 in)
Cable Outer Diameter: Armored section 7.67 mm (0.302 in) maximum; armor ferrule 10.2 mm (0.40 in) maximum; non‑armored section (near connector) 3.68 mm (0.145 in)
Connector Outer Diameter: 7.24 mm (0.285 in) maximum
Minimum Bend Radius: 25.4 mm (1.0 in)
Installation Tips: Before installation, carefully measure the total depth and effective thread depth of the mounting hole. Because the case length is 120 mm but only 15 mm of thread engagement is required, use lock nuts and washers to limit engagement to ≤15 mm; the excess case will remain outside the hole. Use the recommended lock nut (part number 04301008 for M10×1) and tighten to the specified torque. Set the probe gap to the recommended -9 Vdc (approx. 1.27 mm), monitored via the Proximitor Sensor output voltage. The armored section can withstand higher pulling forces, but it is still recommended to attach pulling lines to the cable jacket rather than the connector.
