This module acts as the sophisticated electronic core of a proximity transducer system, converting the eddy current signals from a 25mm probe into a linear voltage output. Specifically designed for applications requiring an extended linear range, this sensor is a critical component for Turbine Supervisory Instrumentation (TSI). Its high-grade construction ensures deterministic data acquisition, allowing for the precise tracking of mechanical motion in critical rotating assets where standard 8mm systems lack the necessary measurement depth.\u003c\/p\u003e\n\u003ch3\u003eHardware Parameters and Engineering Specifications\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3300 XL 25 mm Proximity Transducer System\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDesigned for extended displacement up to 10 mm (approx. 400 mils)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Power:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eStandard -24 Vdc supply with a 50mA maximum current draw\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Sensitivity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePrecisely calibrated to 0.787 V\/mm (20 mV\/mil)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCapable of handling high-frequency data up to 50 kHz for rapid transient capture\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eEnvironmental Sealing:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIP67 rated for complete protection against dust and temporary immersion in industrial fluids\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e-40°C to +85°C (-40°F to +185°F) for extreme industrial climates\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction Material:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCorrosion-resistant housing with CN-specific regional certification compliance\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Integrity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAdvanced RFI\/EMI shielding to prevent data distortion in electrically noisy motor rooms\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIndustrial Deployment and System Utilization\u003c\/h3\u003e\n\u003cp\u003eThe 330850-90-CN Proximitor is the primary choice for monitoring large-bore rotating machinery, such as massive steam turbines, hydroelectric generators, and large-scale industrial process compressors.\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"citation-2248 citation-end-2248\"\u003eBecause of the 25mm system's superior linear range, this sensor is ideally suited for monitoring differential expansion—tracking the relative movement between a machine's rotor and its casing during thermal startup cycles.\u003csup class=\"superscript\"\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eIt is also utilized for axial (thrust) position monitoring on heavy shafts where significant movement is expected.
