330104-00-08-10-02-00 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, 0.0‑inch (0 mm) unthreaded length, 0.8‑inch (approx. 20.3 mm) 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 armor consists of a flexible stainless steel braid with an FEP outer jacket, suitable for harsh industrial environments where mechanical 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) and the cable requires additional mechanical protection. This model is the metric‑thread armored version of the 3300 XL series, commonly used in Europe and other regions that adopt metric standards.
Model Breakdown: 330104-00-08-10-02-00 Configuration Details
Following Bently Nevada’s part number coding system (refer to datasheet Pages 13-15, 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 for M10×1 mounting holes, cable with stainless steel armor |
Unthreaded Length (A) | 00
| 0.0 inches (0 mm) | Distance from probe tip to start of thread; shortest configuration |
Overall Case Length (B) | 08
| 0.8 inches (20.3 mm) | Total threaded length (code 08 = 0.8 in) |
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 the metric thread (M10×1) armored version, without connector protectors or hazardous area approvals. The unthreaded length is 0 mm, meaning the thread starts immediately after the probe tip. The 0.8‑inch (20.3 mm) case length is a short option, suitable for shallow mounting holes. 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.
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., 330104-00-08-10-01-00 or 330104-00-08-10-03-00, 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
330104-00-08-10-02-00 is suitable for the following typical applications:
5‑Meter System + Mechanical Protection (Metric Thread): Paired with a 4.0 m extension cable (e.g., 330130-040-00-00) and a 5 m Proximitor Sensor (e.g., 330180-50-00) to form a complete 5‑meter monitoring system, with armor providing additional mechanical protection. Suitable for equipment with M10×1 metric mounting holes.
Short Case and Armor Required: The 0.8‑inch (20.3 mm) case length is suitable for shallow mounting holes where cable protection is needed, such as near compressors, steam turbines, generators, and other equipment where vibration, friction, or accidental impact may occur.
Conduit Routing (Dry Environments): When cables must be routed through metal conduit or cable trays and connector sealing is not required, armor effectively protects the cable against sharp edges at conduit ends.
High Mechanical Stress Environments (No Oil Exposure): Near large rotating machinery, cables may be subject to crushing or abrasion; armor provides a safety margin while the connector remains in a relatively clean area.
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.
Case Length Selection: The 0.8‑inch short case is suitable for shallow mounting holes. If the mounting hole is deeper, select a metric model with a longer case (e.g., 330104-00-12-10-02-00 for 1.2 inches). Important: The datasheet maximum recommended thread engagement is 1.5 times the nominal diameter (15 mm for M10). Actual engagement should be limited to ≤15 mm using lock nuts and washers.
Unthreaded Length: This model has 0 mm unthreaded length. If your mounting hole has an internal shoulder or you need the probe tip to extend a certain distance, select a metric model with a longer unthreaded length (e.g., code "04" = 40 mm, etc.).
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 (e.g., 330104-00-08-10-01-00).
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., 330104-00-08-10-02-05).
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) (metric torque not specified in the datasheet; refer to imperial approximate)
Overall Case Length: 0.8 in (20.3 mm)
Unthreaded Length: 0.0 in (0 mm)
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, inspect mounting hole threads for cleanliness and depth. Use the recommended lock nut (part number 04301008 for M10×1) and tighten to the specified torque. Effective thread engagement should not exceed 15 mm. 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. Set the probe gap to the recommended -9 Vdc (approx. 1.27 mm), monitored via the Proximitor Sensor output voltage.
