ABB has announced the release of the Endura TBX587 Retractable pH sensor. The Endura TBX587 targets one inch NPT process connections found in sample lines in refineries, chemical plants, and other industrial applications. The temperature compensation element has been moved to the tip of the sensor to provide response times up to 6x faster than conventional gel-filled pH sensors. An optional IP68 Vario Pin style cable connector simplifies sensor replacement without complicated wiring or terminal strips. The mechanical design of the Endura TBX587 includes a large “T” style handle to aid in insertion and retraction into pressurized process pipelines. The new pH sensor is based on ABB’s solid state, Next Step Reference design. The Next Step Reference is designed to withstand chemical poisoning and build-up often found in strong chemical processes and slurries. 316 Stainless hardware is standard with the Endura TBX587 with options for Hastelloy and Titanium metallic fittings.
