The Bently Nevada 330101-00-12-10-11-00 is a high-performance 3300 XL 8 mm Probe designed for critical machinery protection. This sensor is an essential component for measuring radial vibration, axial position, and keyphasor signals in turbines, compressors, and pumps. Manufactured in the U.S.A., this model features a 3/8-24 UNF thread and comes without armor for standard mounting applications.
This particular configuration includes a 1.2-inch overall case length and a 1.0-meter total length. The 330101-00-12-10-11-00 is equipped with a miniature coaxial ClickLoc connector, which includes a connector protector for enhanced durability. Furthermore, the FluidLoc cable option is integrated to prevent oil or other process liquids from leaking out of the machine through the cable's interior, a critical feature for maintaining a clean and safe operating environment.
This 3300 XL series probe incorporates several patented design improvements. For instance, the TipLoc molding method creates a robust bond between the probe tip and its body, significantly reducing the risk of failure. Meanwhile, the CableLoc design provides a pull strength of 330 N (75 lbf), ensuring the cable and tip remain securely attached even under stress. Therefore, this probe offers superior reliability compared to previous generations.
The 330101-00-12-10-11-00 sensor boasts impressive electrical characteristics. Its nominal DC resistance (RPROBE) from the center conductor to the outer conductor is 7.59 ± 0.50 Ω for a 1.0-meter length. Additionally, the extension cable features a typical capacitance of 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 is 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). The recommended gap setting for radial vibration measurement is -9 Vdc, which corresponds to roughly 1.27 mm (50 mils). The Incremental Scale Factor (ISF) for this 1-meter system is a standard 7.87 V/mm (200 mV/mil) ± 5%, including interchangeability error, when measured over the full linear range from 0°C to +45°C.
The robust construction of the 3300 XL 8 mm Probe ensures long-term durability. The probe tip is constructed from molded Polyphenylene sulfide (PPS), providing excellent chemical resistance and structural integrity. Moreover, the probe case is machined from AISI 303 or 304 stainless steel (SST), offering a stronger, more resilient housing that withstands physical abuse. The weight of the cable and probe assembly is 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) for both storage and operation. However, exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. Furthermore, it demonstrates exceptional 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.
Proper installation is crucial for optimal performance of the 330101-00-12-10-11-00. The probe case thread is 3/8-24, with a maximum length of thread engagement of 0.563 inches. For standard forward-mounted probes, the maximum rated torque is 33.9 N•m (300 in•lbf), while the recommended torque is 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).
Additionally, consider the temperature schedule for different hazardous area classifications. For EPL Ga and Gc, the ambient temperature ranges from -55°C to +232°C (T1) down to -55°C to +40°C (T5). Therefore, always verify the classification of your specific environment to ensure safe operation. Remember, this probe is not pressure tested prior to shipment; contact our custom design department if your application requires a pressure seal test.
