Meanwhile, the system integrates easily with PLCs from Siemens or Allen-Bradley. Besides, this model withstands oil, moisture, and high temperatures. Therefore, it suits compressors, pumps, steam turbines, and generators.
Technical Insights
The Bently Nevada 330105-02-12-30-02-00 uses an eddy current principle. This method measures displacement without physical contact. Specifically, the linear range spans from 0.25 mm to 2.29 mm. The operating temperature ranges from -35°C to +120°C. Moreover, the cable assembly includes a 12 mm hex nut for simple mounting. The probe body material resists corrosion in harsh industrial environments. Additionally, this model meets API 670 standards for shaft vibration monitoring. For best performance, pair the Bently Nevada 330105-02-12-30-02-00 with a 3300 XL extension cable and proximity driver.
Installation & Maintenance
Install the Bently Nevada 330105-02-12-30-02-00 with proper gap voltage settings. Firstly, clean the mounting surface and threaded hole thoroughly. Then, set the initial air gap to 1.27 mm (50 mils). Use a torque wrench to tighten the locknut to 10 Nm. Secondly, avoid sharp bends in the probe cable. This prevents internal conductor damage. Meanwhile, inspect the probe tip for debris every three months. Also, measure the extension cable connection resistance. A healthy reading stays below 2 ohms. Finally, recalibrate the entire monitoring loop after any major machine overhaul.
