Key Parameters

Core Features & Advantages

• Extended Linear Range for Large Shaft Movements: The module’s standout feature is its 4.0 mm (160 mils) linear range, which is double that of standard 8 mm probes . This extended range is essential for applications involving large shaft movements, such as axial thrust position measurement on turbines, ramp differential expansion, and rod position monitoring on reciprocating compressors, where 8 mm probes would saturate or lose linearity .

• Proven Eddy-Current Technology with API 670 Compliance: The probe uses eddy-current non-contact sensing technology and fully complies with the American Petroleum Institute’s API 670 Standard for machinery protection systems . This ensures reliable, accurate measurement of shaft vibration and position in the most demanding oil and gas, power generation, and heavy industry applications.

• Robust Construction for Harsh Environments: The probe features an AISI 304 stainless steel case and a PPS (Polyphenylene Sulfide) tip that resists oil, moisture, dust, and chemical contaminants . The 5/8-18 UNF mounting thread is standard for industrial machinery housings, and the miniature ClickLoc™ connector provides a secure, vibration-resistant electrical connection .

• Complete System Interchangeability: The 3300 XL system supports complete interchangeability of probes, extension cables, and Proximitor sensors. The 1.0-meter probe cable is designed to work with a 9.0-meter extension cable (330730-090-xx-xx) to form a complete 10.0-meter system when paired with a 10-meter Proximitor sensor . The 11 mm system also provides a direct upgrade path from legacy 7200-series 11 mm and 14 mm systems .

Typical Applications

The 330707-00-62-10-01-00 is widely used for critical rotating machinery monitoring in demanding industrial applications :

• Steam and Gas Turbines: Axial thrust position and differential expansion measurement where large shaft movements occur

• Centrifugal and Reciprocating Compressors: Rod position monitoring and shaft displacement tracking

• Industrial Motors and Generators: Radial vibration and axial position monitoring on large frames

• Pumps and Gearboxes: Vibration monitoring on critical rotating assets in refineries and chemical plants

Frequently Asked Questions (FAQ)

Q1: What does the model number “330707-00-62-10-01-00” indicate?
A: The breakdown is: 330707 = 3300 XL 11 mm Probe with 5/8-18 UNF thread, without armor; -00 = 0 in unthreaded length (fully threaded); -62 = 6.2 in (157.5 mm) case length; -10 = 1.0 meter cable; -01 = Miniature ClickLoc™ connector with protector, standard cable; -00 = No agency approvals .

Q2: What is the main advantage of the 11 mm probe over an 8 mm probe?
A: The 11 mm probe offers a longer linear range (4.0 mm vs. 2.0 mm) and higher rigidity for larger shafts. It is optimized for measuring large shaft movements such as axial thrust position and differential expansion, while the 8 mm variant is better suited for smaller, tighter installations .

Q3: What is the recommended installation gap for this probe?
A: The recommended gap is 2.5 mm (100 mils). The linear range spans from approximately 0.5 mm to 4.0 mm .

Q4: What scale factor does this probe use?
A: The scale factor is 3.94 V/mm (100 mV/mil), which is different from the 7.87 V/mm (200 mV/mil) used by standard 8 mm probes. This means the Proximitor sensor must be specifically matched for 11 mm systems .

Q5: Can this probe be used with a standard 8 mm Proximitor sensor?
A: No. The 11 mm probe requires a 3300 XL 11 mm Proximitor sensor specifically designed for its scale factor and electrical characteristics. Using an 8 mm Proximitor will result in incorrect measurements .

Q6: What total system length does this 1.0-meter probe require?
A: The 1.0-meter probe cable requires a 9.0-meter extension cable (330730-090-xx-xx) to form a complete 10.0-meter system when paired with a 10-meter Proximitor sensor .

Q7: Does this probe require agency approvals for hazardous areas?
A: This specific model (-00 suffix) has no agency approvals and is suitable for general-purpose environments only. For hazardous area installations, select a variant with the appropriate approval suffix (e.g., -05 for CSA, ATEX, IECEx).

Q8: Can this probe replace older 7200-series probes?
A: Yes, but all components must be replaced—the probe, extension cable, and Proximitor sensor. The monitoring system (e.g., 3500 series) may also require updated configuration software. Partial replacement of only one component will not work due to electrical length and scale factor mismatches .

Choosing the Right Model

• For large shaft movement applications: The 330707-00-62-10-01-00 with its 4.0 mm linear range is the correct choice for axial thrust position and differential expansion measurements where 8 mm probes would saturate .

• For system completion: Pair with a 9.0-meter extension cable (330730-090-xx-xx) and a 10-meter 11 mm Proximitor sensor to form a complete measurement system .

• For hazardous area installations: Select a variant with the -05 suffix for CSA, ATEX, and IECEx certifications.
