3300 XL 8mm Probe 330106-05-30-90-12-00 Bently Nevada

Product Introduction

The Bently Nevada 330106-05-30-90-12-00 is a high-performance reverse mount proximity probe from the industry-leading 3300 XL series. This sensor is engineered for critical rotating machinery monitoring, including radial vibration, axial thrust position, and speed reference measurements. Its M10x1 thread configuration makes it suitable for metric mounting requirements commonly found in European and Asian equipment.

This model comes with a total length of 9.0 meters (29.5 feet), offering ample reach for installations where the probe tip must be positioned far from the junction box. The 330106-05-30-90-12-00 incorporates a Miniature ClickLoc coaxial connector with FluidLoc cable, providing secure signal transmission. Furthermore, its PPS tip material and stainless steel case ensure excellent chemical and thermal resistance.

Technical Specifications

Electrical Characteristics

The 330106-05-30-90-12-00 has a nominal DC resistance of 9.87 ± 0.50 Ω measured from the center conductor to the outer conductor at its full 9.0-meter length. This consistent resistance value ensures reliable signal output to monitoring systems. The connector option is –12, which is a Miniature ClickLoc coaxial type with an integrated FluidLoc cable. Nevertheless, the FluidLoc cable is generally unnecessary for most installations because the probe sleeve already provides adequate protection. Users should carefully evaluate their specific application conditions before selecting this option.

Mechanical Construction

This reverse mount probe features a probe tip made of Polyphenylene sulfide (PPS) , a high-performance engineering thermoplastic that offers excellent dimensional stability and chemical resistance. The probe case is constructed from AISI 303 or 304 stainless steel (SST) , providing superior corrosion resistance and mechanical strength. The case thread is M10x1, with a maximum thread engagement of 15 mm to ensure secure mounting.

The probe cable uses a 75Ω triaxial, fluoroethylene propylene (FEP) insulated design for the standard configuration. For extended temperature applications, a perfluoroalkoxy (PFA) insulated cable is available. Optional armor consists of flexible AISI 302 or 304 SST with an FEP outer jacket. Additionally, the connectors feature gold-plated brass or gold-plated beryllium copper for optimal signal integrity and corrosion resistance.

Mechanical Strength Ratings

The 330106-05-30-90-12-00 demonstrates impressive mechanical durability. Its maximum rated tensile strength is 330 N (75 lbf) from the probe case to the probe lead. Meanwhile, the connection between the probe lead and extension cable connectors supports up to 270 N (60 lbf) . This robust construction ensures reliable operation even in high-vibration environments commonly found in turbomachinery applications.

Environmental Performance

Temperature Ranges

The standard probe operates reliably between –52°C and +177°C (–62°F to +350°F) . For more demanding thermal conditions, the extended temperature range probe tip withstands temperatures up to +218°C (+425°F) . Furthermore, the extended range cable and connector can tolerate temperatures from –51°C to +260°C (–60°F to +500°F) . However, exposing this sensor to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal, so operators should exercise caution in extremely cold environments.

Pressure and Humidity

The 3300 XL 8 mm probes are designed to seal differential pressure between the probe tip and the case using a Viton® O-ring sealing material. It is important to note that these probes are not pressure tested prior to shipment. For applications requiring verified pressure sealing, customers should contact the custom design department to arrange specific testing.

In terms of humidity resistance, the 330106-05-30-90-12-00 exhibits exceptional stability. Testing per IEC standard 68-2-3 shows less than a 3% change in Average Scale Factor (ASF) after 56 days of exposure to 93% relative humidity. This performance ensures measurement accuracy remains consistent even in high-moisture environments.

Hazardous Area Approvals

The Bently Nevada 330106-05-30-90-12-00 carries important hazardous area certifications for versatile deployment. When installed with intrinsically safe zener barriers per drawing 141092, or with galvanic isolators, it achieves Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga classification. Additionally, it meets Class I, Groups A, B, C, D; Class II, Groups E, F, G; and Class III requirements.

Furthermore, when connected with a nonincendive circuit per drawing 140979, this probe qualifies for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc and Class I, Division 2, Groups A, B, C, D certifications. It also meets Class I, Zone 2: AEx/Ex ec llC T5…T1 Gc standards. Temperature classification schedules are provided for both EPL Ga/Gc and Dc applications, with ambient temperature ratings ranging from T1 to T5 depending on specific thermal conditions.

Installation Guidance

Installing the 330106-05-30-90-12-00 correctly ensures optimal performance and longevity. First, verify that the mounting hole is clean and the thread engagement does not exceed 15 mm to avoid damaging the probe or the mounting surface. The M10x1 thread is a metric standard, so use appropriate metric tools and thread sealant during installation.

Next, carefully route the 9.0-meter cable away from high-temperature sources, rotating parts, and sharp edges. The ClickLoc connector provides a positive locking mechanism that prevents accidental disconnection during operation. Additionally, ensure the probe tip remains clean and the target surface is within the specified gap range for accurate linear output.

For most standard installations, the FluidLoc cable option is unnecessary due to the protective probe sleeve. However, we strongly recommend evaluating your specific application environment before omitting this feature. Finally, always follow the manufacturer's torque specifications when tightening the probe to prevent mechanical damage.
