3300 XL Proximity Probe 330708-00-24-10-01-05 | Bently Nevada

Bently Nevada 330708-00-24-10-01-05 Proximity Probe

Product Introduction

The Bently Nevada 330708-00-24-10-01-05 probe serves as a critical component in the 3300 XL eddy-current transducer system. It provides a non-contact method for measuring shaft vibration and position. Consequently, this sensor is vital for protecting turbines, compressors, and pumps from catastrophic failure. The probe's design emphasizes interchangeability, allowing it to work seamlessly with other system components without requiring individual calibration.

This specific model, 330708-00-24-10-01-05, incorporates the patented TipLoc and CableLoc designs. These features ensure a robust mechanical connection and a high pull-strength rating. The probe measures the gap between the probe tip and the conductive target, generating a voltage output proportional to the distance. Therefore, it is an ideal choice for axial (thrust) position monitoring and differential expansion measurements on steam turbines.

Technical Specifications

The Bently Nevada 330708-00-24-10-01-05 is constructed from high-grade materials. The probe tip uses polyphenylene sulfide (PPS), while the case is made from AISI 304 stainless steel (SST). This combination ensures excellent chemical resistance and mechanical strength. The cable is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation, available in total lengths of 1, 5, or 9 meters. Specifically, this model 330708-00-24-10-01-05 has a 1.0-meter cable length.

For electrical performance, the DC resistance from the center conductor to the outer conductor measures 5.9 ± 0.5 ohms for the 1.0-meter version. The operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, exposure to temperatures below -34°C (30°F) may cause premature failure of the pressure seal. The probe also features a Viton O-ring to seal differential pressure between the tip and the case.

Mechanical and Environmental Parameters

The 3300 XL probe family offers versatile mounting options. For the 330708-00-24-10-01-05, the probe case thread is 5/8-18 UNF, with a maximum thread engagement length of 0.938 inches. The recommended installation torque for this case size is 15.2 N•m (133 in•lb), while the maximum rated torque is 45.2 N•m (400 in•lb). Additionally, the connector-to-connector torque should be finger tight, with a maximum of 0.565 N•m (5 in•lb).

Moreover, the minimum bend radius for the probe cable, with or without stainless steel armor, is 25.4 mm (1.0 inch). This specification allows for flexible routing in tight machinery spaces. The probe pressure rating is designed to seal differential pressure effectively, though units are not pressure tested prior to shipment. For applications requiring a pressure test, customers should contact the custom design department. The probe's overall case length is 2.4 inches, as indicated by the "24" option code, and the unthreaded length is 0 inches.

Installation Guidelines

Proper installation of the Bently Nevada 330708-00-24-10-01-05 ensures accurate and reliable measurements. First, clean the mounting threads and the probe case threads to prevent cross-threading. Next, apply a suitable anti-seize compound to the threads if required by your application environment. Then, thread the probe into the mounting hole until the tip reaches the desired air gap.

Furthermore, use a torque wrench to tighten the probe to the recommended 15.2 N•m (133 in•lb). Avoid exceeding the maximum torque of 45.2 N•m (400 in•lb), as this could damage the probe case. After installation, connect the miniature coaxial ClickLoc connector to the extension cable, tightening it finger tight only. Do not use tools on the connector, as this may damage the connection. Finally, verify the air gap using a calibrated proximity probe driver and power supply to ensure the output voltage is within the linear range.

Frequently Asked Questions

Q1: What is the difference between the 330708-00-24-10-01-05 and other 3300 XL probes?
The 330708-00-24-10-01-05 specifically has a 5/8-18 UNF thread, no armor, a 2.4-inch case length, a 1.0-meter cable, and a ClickLoc connector with multiple agency approvals. Other models may have metric threads, different case lengths, or armored cables.

Q2: Can this probe be used in hazardous areas?
Yes, the "05" agency approval option indicates multiple approvals, which typically include ATEX, CSA, and FM certifications for hazardous locations. However, always verify the specific approval markings on the probe against your local requirements.

Q3: How do I determine the correct air gap for installation?
The air gap depends on the target material and the driver system. For a standard 3300 XL driver, the linear range is typically between 0.25 mm and 2.0 mm. Always consult the system manual for specific calibration data.

Q4: What should I do if the probe cable is damaged?
The 330708-00-24-10-01-05 has an integral cable that cannot be field-repaired. You must replace the entire probe assembly if the cable is cut or crushed. Contact your supplier for a replacement unit.

Q5: How long is the shipping time, and which carriers do you use?
We ship all probes via FedEx, UPS, or DHL. Standard delivery takes 3 to 5 business days for most regions. Express shipping options are also available for urgent requirements.
