Retractable pH Sensor for Tough Industrial Applications
ABB has released the Endura TBX587 Retractable pH sensor. The Endura TBX587 targets smaller, one-inch NPT process connections found in sample lines in refineries, chemical plants and other industrial applications. The Endura TBX587 incorporates several design elements requested by customers into one pH measurement system. The temperature compensation element has been moved to the tip of the sensor to provide response times up to 6x faster then 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 pH sensor is based on ABB’s solid state, Next Step Reference design. The Next Step Reference is designed to withstand chemical poisoning and buildup often found in strong chemical processes and slurries. The Endura TBX587 features 316 stainless hardware with options for hastelloy and titanium metallic fittings.
This product, combined with the ABB TB(X)557 low pressure retractable sensor, the TB(X)564 high pressure retractable sensor and the TB18 Safe-T-Clean valve, allows ABB to address nearly any insertion-style pH sensor installation.
