3300 XL 8 mm Probe Bently Nevada 330101-00-16-50-02-05

3300 XL 8 mm Probe Bently Nevada 330101-00-16-50-02-05

Product Introduction

The Bently Nevada 330101-00-16-50-02-05 belongs to the trusted 3300 XL series of proximity sensors. This 8 mm probe features a 3/8-24 UNF thread and comes without armor for flexible installation. Its 5.0-meter total length works exclusively with the 5-meter Proximitor sensor system. The probe incorporates patented TipLoc and CableLoc technologies for superior durability. Additionally, the miniature coaxial ClickLoc connector ensures a secure and reliable connection. This model also includes CSA, ATEX, and IECEx approvals, making it suitable for demanding industrial environments.

Technical Specifications

Electrical Characteristics

The 330101-00-16-50-02-05 offers precise measurement capabilities. Its nominal DC resistance from center to outer conductor is 8.73 ± 0.50 Ω for the 5-meter length. The extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable. The maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet).

Linear Range and Scale Factor

This probe delivers a 2 mm (80 mils) linear range starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, which equals roughly 1.27 mm (50 mils). The incremental scale factor stands at 7.87 V/mm (200 mV/mil) with ±5% accuracy for 5-meter systems. Deviation from the best fit straight line remains less than ±0.025 mm (±1 mil) from 0°C to +45°C.

Temperature and Environmental Ratings

The standard probe operates from -52°C to +177°C (-62°F to +350°F) for both storage and operation. Furthermore, the probe tip uses Polyphenylene sulfide (PPS) material, while the case is made from AISI 303 or 304 stainless steel. The relative humidity test shows less than a 3% change in average scale factor when exposed to 93% humidity for up to 56 days.

Mechanical and Physical Parameters

Construction and Durability

The 3300 XL probe incorporates a patented TipLoc molding method. This creates a robust bond between the probe tip and the probe body. Moreover, the CableLoc design delivers 330 N (75 lbf) pull strength for secure cable attachment. The larger 8 mm diameter provides thicker encapsulation of the probe coil, resulting in a more rugged probe overall.

Thread and Torque Specifications

The probe case features a 3/8-24 UNF thread with a maximum engagement length of 0.563 inches. For standard forward-mounted probes, the maximum rated torque is 33.9 N•m (300 in•lbf), with a recommended value of 11.2 N•m (100 in•lbf). For the first three threads only, the maximum rated torque is 22.6 N•m (200 in•lbf) with a recommended setting of 7.5 N•m (66 in•lbf).

Pressure and Sealing

The 330101-00-16-50-02-05 is designed to seal differential pressure between the probe tip and case. The sealing uses a Viton® O-ring. Probes are not pressure tested prior to shipment, but custom testing is available upon request.

Installation Guidelines

Mounting Instructions

First, ensure the mounting hole is clean and free from debris. Next, thread the probe into the mounting hole using the 3/8-24 UNF threads. Apply the recommended torque of 11.2 N•m for standard installations. For the first three threads, use 7.5 N•m to avoid damage. Meanwhile, set the initial gap to achieve -9 Vdc output for radial vibration monitoring.

Cable Routing and Connection

Connect the miniature coaxial ClickLoc connector to the extension cable or directly to the Proximitor sensor. Subsequently, route the cable away from high-temperature surfaces and moving parts. Avoid sharp bends that could damage the cable. For field wiring, use 3-conductor shielded triad cable and tinned wiring for best results.

System Configuration

This 5-meter probe must pair exclusively with a 5-meter Proximitor sensor system. The system supports up to 305 meters of field wiring between the sensor and monitor. However, longer wiring may affect high-frequency response, as shown in the frequency response graphs.

Frequently Asked Questions

1. What is the total length of the Bently Nevada 330101-00-16-50-02-05 probe?
This probe has a total length of 5.0 meters (16.4 feet). It is specifically designed for use with the 5-meter Proximitor sensor system only.

2. What approvals does the 3300 XL 8 mm probe carry?
The Bently Nevada 330101-00-16-50-02-05 holds CSA, ATEX, and IECEx approvals for use in hazardous and explosive atmospheres.

3. What is the recommended gap setting for this probe?
The recommended gap setting for radial vibration measurement is -9 Vdc, which corresponds to approximately 1.27 mm (50 mils) from the target surface.

4. Can I use this probe with a different length Proximitor sensor?
No, this 5-meter probe must pair exclusively with a 5-meter Proximitor sensor. Using mismatched lengths will result in inaccurate measurements.

5. What is the maximum operating temperature for the standard version?
The standard probe operates from -52°C to +177°C (-62°F to +350°F). However, exposing the probe to temperatures below -34°C (-30°F) may cause premature pressure seal failure.
