330104-00-04-10-02-00 Armored Eddy Current Probe

330104-00-04-10-02-00 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 mm unthreaded length, 40 mm (approx. 1.57 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 40 mm case length is a medium option, longer than the standard 20 mm case, suitable for applications requiring deeper thread engagement or slightly thicker mounting flanges, but without the need for an extra‑long case. The armor provides mechanical protection for the cable in industrial environments where crushing, pulling, or abrasion risks exist.

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 case, commonly used in Europe and other metric‑standard regions.

Model Breakdown: 330104-00-04-10-02-00 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:

Key Configuration Note: This model is a metric thread (M10×1) armored probe with 40 mm case length, longer than the standard 20 mm case, suitable for deeper thread engagement or slightly thicker mounting flanges. The unthreaded length is 0 mm, meaning the thread starts immediately after the probe tip. 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., 330104-00-04-10-01-00, 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

330104-00-04-10-02-00 is suitable for the following typical applications:

1. 5‑Meter System + Mechanical Protection (Metric Thread, Medium Case): Paired with a 4.0 m extension cable and a 5 m Proximitor Sensor to form a complete 5‑meter monitoring system. Suitable for equipment with M10×1 metric mounting holes where cable protection is needed and the case length of 40 mm is preferable over the standard 20 mm for slightly deeper holes or thicker flanges.

2. Medium‑Depth Mounting Holes: When the mounting hole depth is between 20 mm and 40 mm, this model takes advantage of the longer case for a more secure installation.

3. Conduit Routing + High Mechanical Stress Environments: Armor protects the cable from damage during conduit routing or in high‑vibration environments.

4. Rotating Machinery (Compressors, Turbines, Generators): Near such equipment, cables may be subject to vibration, friction, or accidental impact; armor provides a safety margin.

5. 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 40 mm case is suitable for medium‑depth mounting holes. For shallower holes (<20 mm), choose a 20 mm case (e.g., 330104-00-02-10-02-00); for deeper holes, consider 60 mm, 80 mm, or longer cases. Important: The datasheet maximum recommended thread engagement is 1.5 times the nominal diameter (15 mm for M10). Limit actual engagement to ≤15 mm using lock nuts and washers. Excess case length will remain outside the mounting hole; be aware of potential space interference.

• 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 model with a longer unthreaded length (e.g., code "02" = 20 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.

• 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., 330104-00-04-10-02-05).

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: 40 mm (1.57 in)

• Unthreaded Length: 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. Since the case length is 40 mm, the excess length beyond the engaged threads will remain outside the hole; ensure adequate clearance. 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.
