Critical Technical Specifications

• Brand & Model: 330103-00-04-20-02-CN Bently Nevada (3300 XL 8 mm System, Metric).
• 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 7.88 ± 0.50 Ω for the 2.0-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.

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 0 mm and a 40 mm case length. The total length option '20' provides a 2.0-meter (6.6 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.

Country Specific Approval & Compliance

• Agency Approval Option: This unit includes the 'CN' option for country specific requirements. It meets local certification standards for the Chinese market.
• Connector Type: Features a '02' option: Miniature coaxial ClickLoc connector with standard cable. This ensures a secure, reliable connection in the field.
• 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.

Frequently Asked Questions

What does the 'CN' approval option mean for this probe?

The 'CN' option on your 330103-00-04-20-02-CN indicates country specific certification for China. It meets the local regulatory requirements for installation in that region. This ensures compliance without needing the standard CSA, ATEX, or IECEx marks.

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

Your 330103-00-04-20-02-CN 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 does the 2.0-meter cable length help with installation?

The 2.0-meter total length (Option 20) provides extra reach from the probe to the junction box. This longer cable helps you avoid splicing or extending leads in tight spaces. It simplifies routing in large machinery trains.

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.
