Critical Technical Specifications

• Brand & Model: 330103-02-08-10-02-05 Bently Nevada (3300 XL 8 mm System).
• Measurement Range: Offers a 2 mm (80 mils) linear range. It starts at 0.25 mm from the target and extends to 2.3 mm. This equates to a -1 to -17 Vdc output for precise gap analysis.
• Recommended Gap Setting: For radial vibration monitoring, we recommend a gap of -9 Vdc. This typically corresponds to a 1.27 mm (50 mils) physical gap.
• DC Resistance: The nominal probe resistance (RPROBE) is 7.59 ± 0.50 Ω for the 1.0-meter length. This ensures consistent signal integrity.
• Frequency Response: You can use field wiring up to 305 meters (1000 feet) between the proximitor and the monitor. Refer to standard frequency response graphs for high-frequency roll-off details.

Superior Environmental & Mechanical Design

• Temperature Tolerance: This standard probe operates from -52°C to +177°C. It withstands harsh conditions without performance loss.
• Pressure Seal: A Viton® O-ring seals the differential pressure between the tip and case. Contact us if you require a specific pressure test prior to shipment.
• Material Construction: Features a rugged probe tip made of Polyphenylene Sulfide (PPS). The probe case utilizes AISI 303 or 304 stainless steel for durability.
• Humidity Resistance: It shows less than a 3% change in Average Scale Factor after 56 days of 93% humidity testing. This complies with IEC standard 68-2-3.

Hazardous Area Approvals & Safety Compliance

• Agency Approval Option: This unit includes the '05' option for global certifications. It meets CSA, ATEX, and IECEx standards for hazardous locations.
• Intrinsic Safety (Ia): When using zener barriers or galvanic isolators, it suits Class I, Zone 0 environments. It carries AEx/Ex ia IIC T5...T1 Ga ratings.
• Non-Incendive (nA, ec): For Division 2 applications, install it with a non-incendive circuit per drawing 140979. It supports Class I, Zone 2 and Class 1, Division 2 groups.
• Connector Type: Features a '02' option: Miniature coaxial ClickLoc connector with standard cable. This ensures a secure, reliable connection in the field.

Installation & Mechanical Details

• Thread Specifications: Employs an M10 x 1 thread without armor. The maximum length of thread engagement is 15 mm.
• Physical Dimensions: This probe has an unthreaded length of 20 mm and a case length of 80 mm. The total length option '10' provides a 1.0-meter (3.3 feet) cable.
• Field Wiring: Use 0.2 to 1.5 mm² (16 to 24 AWG) wire. We recommend a 3-conductor shielded triad cable with tinned wiring for optimal performance.
• Weight: The probe weighs approximately 323 g/m (11.4 oz/ft), providing a substantial and durable feel during handling.

Frequently Asked Questions

What is the purpose of the 20 mm unthreaded length?

The 20 mm unthreaded option (Option 02) on your 330103-02-08-10-02-05 provides a smooth section before the threads start. This design helps you position the probe deeper into a mounting hole. It also allows the probe to pass through packing glands or seals without damaging the threads.

What is the difference between the standard and extended temperature range?

Your 330103-02-08-10-02-05 is a standard probe, rated to +177°C. The extended range probe survives up to +218°C at the tip. Exposing this standard model to temperatures below -34°C may stress the pressure seal. Choose the extended option if your ambient temperature consistently exceeds +177°C.

Can I use this probe with my existing 3300 series monitors?

Yes. We designed this 3300 XL 8 mm probe specifically for seamless integration with 3300 XL Proximitor Sensors. You can then connect it to most Bently Nevada monitors. Ensure your field wiring does not exceed 305 meters to maintain signal fidelity.

How do the 20 mm unthreaded and 80 mm case lengths work together?

The 20 mm unthreaded section allows the tip to extend beyond the mounting surface. The 80 mm case provides the rigid body that houses the internal components. Together, they let you reach the target area while keeping the threaded section securely engaged in the mounting boss.

What if my application requires a pressure test certificate?

Standard probes do not ship with a pressure test. If your specific reliability standards require a documented test, please contact our custom design department before ordering. They can arrange for a test of the pressure seal on your units.
