This unit combines a 3300 XL proximity probe, an extension cable, and a Proximitor sensor into a single, environmentally hardened assembly. Designed specifically for critical assets like steam turbines and centrifugal compressors, the PROXPAC XL simplifies installation by housing the sensitive electronics directly at the measurement point within a rugged, weather-proof enclosure.\u003c\/p\u003e\n\u003cp\u003eBy utilizing non-contact eddy current technology, this transducer captures shaft vibration and axial position with microscopic precision. The integrated design eliminates the need for external Proximitor housings and long, unprotected coaxial runs, significantly reducing signal interference and installation costs. Whether monitoring fluid-film bearings or high-speed rotors, the 330881-16-05-150-00-02 ensures maximum uptime by delivering high-fidelity data to your Turbine Supervisory Instrumentation (TSI) system.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eTechnical Configuration\u003c\/h2\u003e\n\u003cp\u003eThe model\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e330881-16-05-150-00-02\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eutilizes a modular engineering code to define its mechanical dimensions and electrical calibration:\u003c\/p\u003e\n\u003ch3\u003eProbe Option (-16)\u003c\/h3\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e-16\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003especifies a probe with a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e1.6-inch\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e(approx. 41mm) total case length.
