Technical Specifications

Suffix Code Explanation

Core Advantages

1. Purpose-Built for Confined Hazardous Areas

The 50 mm ultra-compact case length makes this probe ideal for installation in space-constrained hazardous locations where standard-length probes cannot fit . Combined with full hazardous area certification, it delivers maximum safety in minimum space.

2. FluidLoc Chemical-Resistant Cable

The FluidLoc cable construction prevents oil or other fluids from migrating through the cable interior. This is critical in chemical processing, oil and gas, and pharmaceutical applications where cable degradation could compromise both measurement integrity and safety .

3. Comprehensive Hazardous Area Approvals

With CSA, ATEX, and IECEx certifications covering Class I, Zone 0/1/2 and Division 1/2, this probe is approved for the most demanding explosive atmosphere applications . This eliminates the need for external barriers when used with approved intrinsically safe circuits.

4. ClickLoc™ Connector with Protector

The gold-plated ClickLoc™ connector requires only finger-tight torque and features a patented locking mechanism. The added connector protector (Option 11) shields the connection point from moisture, contaminants, and mechanical damage in harsh environments .

5. Industry-Standard Reliability

The 3300 XL series fully complies with API 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability. All system components are electrically and mechanically interchangeable, simplifying maintenance and reducing spare parts inventory .

System Integration Notes

The 3300 XL System is a Matched Set

A complete 3300 XL measurement system consists of three parts that must have consistent electrical lengths :

1. Proximity Probe (this item) – Mounts inside the machine, facing the shaft

2. Extension Cable – Links the probe to the Proximitor Sensor

3. Proximitor Sensor – Powers the probe and converts the signal to a usable output

Important: The total system electrical length (probe length + extension cable length) must equal the Proximitor Sensor's design length (typically 5 or 9 meters). This 1.0 m probe is typically paired with a 4.0 m extension cable to create a 5.0 m system .

Mounting

• Thread: M10 × 1.0 mm, max thread engagement of 15 mm 

• Recommended Gap: Set to -9 Vdc at 1.27 mm 

• Minimum Shaft Diameter: 50.8 mm (2 in)

Hazardous Area Installation

• When installed in explosive atmospheres, use appropriate intrinsic safety barriers or approved circuits

• Verify that the Proximitor sensor and extension cable are also rated for the hazardous area classification

• Follow all local electrical codes for intrinsically safe installations

Frequently Asked Questions (FAQ)

Q1: What is the Bently Nevada 330103-00-05-10-11-05?

It is a hazardous-area certified 8 mm proximity probe from the 3300 XL series, used for non-contact measurement of shaft vibration and position in explosive atmosphere applications. This variant features M10 × 1 threading, a 50 mm ultra-compact case, and a FluidLoc chemical-resistant cable .

Q2: What does each suffix in the part number mean?

00 = 0 mm unthreaded length (fully threaded); 05 = 50 mm ultra-compact case length; 10 = 1.0 meter total length; 11 = Miniature ClickLoc™ connector with protector, FluidLoc cable; 05 = CSA, ATEX, IECEx hazardous area approvals .

Q3: What is the advantage of the FluidLoc cable?

FluidLoc cable construction prevents oil or other fluids from leaking through the cable interior. This protects both the measurement signal and the surrounding environment in chemical, oil and gas, and pharmaceutical applications .

Q4: What hazardous area certifications does this probe have?

The probe carries CSA, ATEX, and IECEx certifications for Class I, Zone 0/1/2 and Division 1/2, with protection level Ex ia IIC T5-T1 Ga .

Q5: What is the total cable length of this probe?

The total length is 1.0 meter (3.3 feet) .

Q6: What thread type does this probe use?

It uses an M10 × 1.0 mm metric thread with maximum thread engagement of 15 mm .

Q7: What is the linear range and sensitivity?

The linear range is 2.0 mm (80 mils) with a sensitivity of 7.87 V/mm (200 mV/mil) when used with a 3300 XL Proximitor sensor .

Q8: What is the operating temperature range?

The probe operates from -52°C to +177°C (-62°F to +351°F) .

Q9: What connector does this probe have?

It features a Miniature Coaxial ClickLoc™ connector with a protector. The gold-plated connector requires only finger-tight torque and features a locking mechanism .

Q10: Does this probe require a specific extension cable and Proximitor?

Yes. The 3300 XL system requires matching parts with a total electrical length of 5 or 9 meters. This 1.0 m probe is typically paired with a 4.0 m extension cable to create a 5.0 m system matching a 5.0 m Proximitor sensor .

Q11: Why is this probe considered "compact"?

The 50 mm case length is significantly shorter than standard 3300 XL probes (typically 100–200 mm), allowing installation in confined spaces where longer probes cannot fit .

Q12: Can I use this probe with older 3300 series systems?

Yes. The 3300 XL 8 mm probes are backward-compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components .

Q13: What documentation accompanies this probe?

The probe is supplied with full certification files for CSA, ATEX, and IECEx standards .
