Built with an AISI 304 stainless steel case, a rugged polyphenylene sulfide (PPS) probe tip, and a 9.0-meter high-temperature PFA-insulated FluidLoc triaxial cable, this probe maintains continuous measurement accuracy up to 200°C (392°F) and tolerates short-term excursions up to 250°C (482°F) for under 24 hours.\u003c\/p\u003e\n\u003cp\u003eGlobal PLC Spare HUB's Insight: During a high-temperature turbine overhaul at a major combined-cycle power station in Germany, our mechanical diagnostic team installed the \u003cspan style=\"color: #0056b3;\"\u003e\u003cstrong\u003e330876-02-90-01-05\u003c\/strong\u003e\u003c\/span\u003e on the high-pressure steam turbine DE journal.
