The Bently Nevada 330909-05-25-10-02-00 is a precision-engineered proximity probe from the trusted 3300 NSv series. This model offers a total length of 1.0 meter and incorporates a robust armor layer for enhanced cable protection. Its primary function is to provide accurate, non-contact measurement of shaft vibration and position. Therefore, it plays a vital role in the predictive maintenance and protection of expensive rotating assets. Furthermore, the probe's construction uses high-grade materials like AISI304 stainless steel and PPS, ensuring longevity in harsh industrial environments.
This section details the core technical attributes of the 3300 NSv probe.
Model Configuration: The product number 330909-05-25-10-02-00 breaks down as follows: '05' specifies a 0.5-inch unthreaded length, '25' indicates a 2.5-inch overall case length, '10' denotes a 1.0-meter total cable length, and '02' signifies a miniature coaxial ClickLoc connector with standard cable.
Electrical Characteristics: The probe operates with a 75 Ω coaxial cable and features fluoroethylene propylene (FEP) insulation. For this 1.0-meter version, the DC resistance from the center conductor to the outer conductor (RPROBE) is precisely 4.2 ± 0.5 ohms.
Mechanical Construction: The case is machined from AISI304 stainless steel (SST), providing excellent corrosion resistance. Moreover, the probe tip is made from Polyphenylene sulfide (PPS), a material known for its stability and insulation properties.
Connector Type: It comes equipped with a miniature coaxial ClickLoc connector, which ensures a secure and reliable connection to the extension cable, preventing signal loss.
Understanding the environmental limits is crucial for proper application of the 330909-05-25-10-02-00.
Torque Specifications: For installation, adhere to the recommended torque of 11.3 N•m (100 in•lb) for the 3/8-24 UNF probe case. For the first three threads, use 7.5 N•m (66 in•lb). The maximum rated torque is 33.9 N•m (300 in•lb).
Thread Engagement: The maximum recommended length of thread engagement for the 3/8-24 case is 0.563 inches. This ensures proper mechanical stability and sensor gap.
Temperature Range: The probe supports an operating and storage temperature range of -52°C to +177°C (-62°F to +351°F). However, prolonged exposure below -34°C (-30°F) may compromise the pressure seal.
Pressure Capability: This 3300 NSv probe is engineered to seal differential pressure between the tip and case using a Viton O-ring. It is important to note that probes are not pressure tested prior to shipment.
Weight: The unit weighs approximately 14 to 150 grams (0.5 to 5.3 oz), depending on the cable length.
Proper installation of the Bently Nevada 330909 is key to achieving accurate measurements. First, verify the thread engagement to avoid damaging the probe case or the mounting hole. Specifically, use a torque wrench to apply the recommended tightening values. Next, ensure the target surface is clean and within the probe's specified linear range. Additionally, avoid running the cable near high-voltage sources to prevent electrical interference. Finally, secure the cable with appropriate clamps to prevent strain on the connector and the armor.
