Specifically designed to monitor vibration on gas turbines, steam turbines, and other rotating machinery where surface temperatures exceed the limits of standard sensors, this two-wire transducer provides a self-generated electrical signal proportional to vibration velocity. Its robust construction ensures reliable performance in the high-heat zones of power generation and petrochemical facilities, allowing for continuous monitoring of critical assets to prevent costly mechanical failure and extend the Mean Time Between Failures (MTBF).\u003c\/p\u003e\n\u003ch3\u003eSuffix Logic Breakdown\u003c\/h3\u003e\n\u003cp\u003eThe specific hardware configuration for the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e74712-06-05-04-00\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eis defined by the following industrial options:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e74712\u003c\/strong\u003e: Base model for the High-Temperature Two-Wire Velocity Transducer.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan class=\"citation-90\"\u003e\u003c\/span\u003e\u003cstrong\u003e06 (Mounting Angle\/Freq Option)\u003c\/strong\u003e\u003cspan class=\"citation-90 citation-end-90\"\u003e: Optimized for a mounting angle of 0 plus or minus 100 degrees, with a minimum operating frequency of 10 Hz (600 cpm).\u003csup class=\"superscript\"\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e05 (Mounting Base Option)\u003c\/strong\u003e: Supplied without a base;
