330101-00-12-10-02-00 is a Bently Nevada 3300 XL series standard eddy current probe with a total length of 1.0 meter (3.3 feet). This model features 3/8-24 UNF threads, 0.0‑inch unthreaded length, 1.2‑inch overall case length, a standard ClickLoc coaxial connector, and standard FEP‑insulated cable. It does not include armor or hazardous area approvals. Its distinguishing feature is the longer case length of 1.2 inches (compared to the standard 0.8 inches), making it suitable for deeper threaded mounting holes or applications where the probe needs to be inserted further into the equipment.
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), ideal for installations where the Proximitor Sensor is mounted close to the equipment (e.g., in a junction box).
Model Breakdown: 330101-00-12-10-02-00 Configuration Details
Following Bently Nevada’s part number coding system (refer to datasheet Pages 13-14), the fields in this model number represent the following:
Field | Code | Parameter | Description |
Base Model | 330101
| 3300 XL 8 mm Probe, 3/8-24 UNF thread, without armor | Compatible with 3300 XL 8 mm and 3300 5 mm systems |
Unthreaded Length (A) | 00
| 0.0 inches | Distance from probe tip to start of thread; shortest configuration |
Overall Case Length (B) | 12
| 1.2 inches | Total threaded length (code 12 = 1.2 inches) |
Total Length Option (C) | 10
| 1.0 meter (3.3 ft) | Total probe cable length (including connector) |
Connector & Cable Option (D) | 02
| Miniature coaxial ClickLoc connector, standard cable | Standard FEP‑insulated cable, gold‑plated ClickLoc connector |
Agency Approval (E) | 00
| Not required | Standard industrial version for non‑hazardous areas |
Key Configuration Note: The defining feature of this model is its 1.2‑inch case length, longer than the common 0.8‑inch case, making it suitable for installations requiring deeper thread engagement or thicker mounting flanges. The 1.0 m total length is intended for 5‑meter systems (paired with a 4.0 m extension cable). The unthreaded length is 0.0 inches, meaning the thread starts immediately after the probe tip.
Application Scenarios & Selection Guide
330101-00-12-10-02-00 is suitable for the following typical applications:
Standard 5‑Meter System Configuration: 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, ideal for compact layouts where the Proximitor Sensor is mounted near the equipment (e.g., in the same junction box or on the equipment casing).
Installations Requiring Longer Thread Engagement: The 1.2‑inch case length (approx. 30.5 mm) is longer than the standard 0.8 inches, suitable for deeper mounting holes or applications where the probe needs to be inserted further into the equipment, such as thick-walled housings or equipment with thick mounting flanges.
Radial Vibration Monitoring: Suitable for shaft vibration measurement on fluid‑film bearing machines such as compressors, steam turbines, generators, and pumps.
Axial Position (Thrust) Monitoring: Can be used to measure rotor axial position and monitor thrust bearing wear.
Keyphasor / Speed Measurement: Can serve as a Keyphasor probe to provide speed reference signals.
Standard Industrial Environments: No armor, 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.
Case Length Selection: This model has a 1.2‑inch case length. Before installation, verify that the mounting hole depth can accommodate this longer thread. If the mounting hole is shallow, select a model with a 0.8‑inch case length (e.g., 330101-00-08-10-02-00). Thread engagement should not exceed the datasheet maximum (0.563 inches) to avoid installation difficulty or probe damage.
Unthreaded Length: This model has 0.0‑inch 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 "04" = 0.4 inches).
Ambient Temperature: Standard probe is rated to +177°C. If the application exceeds this temperature, select an ETR high‑temperature probe (330191/330192 series).
Hazardous Area Requirements: If the installation area has explosive gas atmospheres, select the version with hazardous area approvals (e.g., 330101-00-12-10-02-05).
Armor Protection: If the cable may be subject to mechanical damage (crushing, abrasion), select an armored version (e.g., 330102 base model or the same specification with armor).
Mechanical Dimensions & Installation
Probe Tip Diameter: 8.0 mm (0.31 in)
Thread Specification: 3/8-24 UNF-2A; recommended lock nut torque: 11.2 N·m (100 in·lbf)
Overall Case Length: 1.2 in (30.5 mm)
Unthreaded Length: 0.0 in
Cable Outer Diameter: 3.68 mm (0.145 in) maximum
Connector Outer Diameter: 7.24 mm (0.285 in) maximum
Minimum Bend Radius: 25.4 mm (1.0 in)
Installation Tips: Before installation, inspect the mounting hole threads for cleanliness and proper depth. Because the case is longer, ensure the mounting hole has sufficient depth to accommodate the full thread length. Use the recommended Bently Nevada lock nut (part number 04301007) and tighten to the specified torque. Set the probe gap to the recommended -9 Vdc (approx. 1.27 mm), which can be monitored via the Proximitor Sensor output voltage.
