Bently Nevada 330101-10-27-05-02-05 - 3300 XL Probe

330101-10-27-05-02-05 Bently Nevada Sensor, 0.5 Meter

Product Introduction

The Bently Nevada 330101-10-27-05-02-05 is a certified 3300 XL 8 mm Probe engineered for machinery protection in potentially explosive environments. This sensor excels at measuring radial vibration, thrust position, and speed on critical rotating equipment like compressors, pumps, and gas turbines. Manufactured in the U.S.A., this model features a 3/8-24 UNF thread and comes without armor, offering a cost-effective solution for standard mounting holes.

This specific configuration includes a 1.0-inch unthreaded length and a 2.7-inch overall case length. The 330101-10-27-05-02-05 is equipped with a 0.5-meter (1.6 feet) total length and a miniature coaxial ClickLoc connector with a standard cable. Most importantly, this probe carries the Agency Approval Option 05, which includes CSA, ATEX, and IECEx certifications. Therefore, it is perfectly suited for installation in areas classified as hazardous according to international standards.

This 3300 XL series probe builds on proven technology with several patented advancements. For example, the TipLoc molding method ensures a robust bond between the probe tip and body, preventing separation. Simultaneously, the CableLoc design provides a pull strength of 330 N (75 lbf), securely attaching the cable to the probe tip. Consequently, this sensor offers exceptional reliability and longevity in demanding industrial applications.

Technical Specifications

The 330101-10-27-05-02-05 sensor delivers consistent and accurate electrical performance. Its nominal DC resistance (RPROBE) is 7.45 ± 0.50 Ω for the 0.5-meter length. Additionally, the extension cable capacitance is typically 69.9 pF/m (21.3 pF/ft). For field wiring, we recommend using a 3-conductor shielded triad cable, 16 to 24 AWG, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor.

Specifically, the linear range of this probe spans 2 mm (80 mils), starting at roughly 0.25 mm (10 mils) and extending to 2.3 mm (90 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). The Incremental Scale Factor (ISF) is a standard 7.87 V/mm (200 mV/mil) ± 5%, including interchangeability error, when measured over the 80-mil linear range from 0°C to +45°C. Furthermore, the Deviation from Best Fit Straight Line (DSL) is less than ±0.025 mm (±1 mil) under the same conditions.

Mechanical and Environmental Parameters

The construction of the 3300 XL 8 mm Probe prioritizes durability in harsh settings. The probe tip uses molded Polyphenylene sulfide (PPS), offering excellent resistance to chemicals and wear. Moreover, the case is machined from AISI 303 or 304 stainless steel (SST), providing a strong, rigid housing. The cable and probe assembly weighs 323 g/m (11.4 oz).

In terms of environmental resilience, the standard probe operates within a temperature range of -52°C to +177°C (-62°F to +350°F). However, exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. The probe uses a Viton® O-ring to seal differential pressure between the tip and case. Additionally, it demonstrates outstanding humidity resistance, with less than a 3% change in Average Scale Factor (ASF) after 56 days of testing in 93% relative humidity per IEC standard 68-2-3.

Hazardous Area Approvals and Temperature Schedule

The 330101-10-27-05-02-05 distinguishes itself with its comprehensive agency approvals. Specifically, the Agency Approval Option 05 includes CSA, ATEX, and IECEx certifications. This makes the probe suitable for use in explosive atmospheres defined by these regulatory bodies.

For EPL Ga and Gc (gas environments), the probe has the following temperature classifications:

• T1: Ambient -55°C to +232°C

• T2: Ambient -55°C to +177°C

• T3: Ambient -55°C to +120°C

• T4: Ambient -55°C to +80°C

• T5: Ambient -55°C to +40°C

For EPL Dc (dust environments), the classifications are:

• T280°C: Ambient -55°C to +232°C

• T225°C: Ambient -55°C to +177°C

• T170°C: Ambient -55°C to +120°C

• T130°C: Ambient -55°C to +80°C

• T105°C: Ambient -55°C to +100°C

• T90°C: Ambient -55°C to +40°C

Always verify the temperature classification of your specific hazardous area to ensure safe operation.

Installation Guidelines

Correct installation is essential for the optimal performance of the 330101-10-27-05-02-05. The probe case thread is 3/8-24, and the maximum length of thread engagement is 0.563 inches. For standard forward-mounted probes, the maximum rated torque is 33.9 N•m (300 in•lbf), with a recommended torque of 11.2 N•m (100 in•lbf). For the first three threads, the maximum rated torque is 22.6 N•m (200 in•lbf), with a recommended setting of 7.5 N•m (66 in•lbf).

Remember, this probe is not pressure tested before shipment. Therefore, contact our custom design department if your application requires a pressure seal test. Furthermore, ensure that the field wiring and connections comply with the hazardous area certification requirements. Using the correct gland and cable entry method is critical for maintaining the integrity of the explosion-proof installation.
