The Endura TBX587 is a retractable combination pH and redox (ORP) sensor designed for installation in 1-inch process lines, featuring a compact body with a T-handle for easy insertion and removal in pressurized systems. It incorporates a solid-state Next Step reference electrode to prevent poisoning and plugging, and includes a solution ground rod for continuous diagnostics. The sensor offers integral temperature compensation with either a Pt100 or 3 kΩ Balco thermoresistor, supporting operating temperatures up to 140 °C with selected glass electrodes. Wetted materials include PVDF, stainless steel, titanium, or Hastelloy, with EPDM, Viton, or Kalrez O-rings. Cable connections are available as pinned leads or IP68-rated VarioPin quick-disconnect. Dimensions are 279 mm (11 in) in length with a 1-inch full port. The sensor is rated for maximum pressure of 150 psig (10.3 bar).
The Endura pH / Redox (ORP) Sensor TBX587 is the latest addition to our comprehensive industrial pH sensor product line. This new pH sensor uses the familiar solid state Next Step Reference design offered in our TB5 and TBX5 product lines.
The sensor targets smaller 1 in. process connections found in sample lines in refineries, chemical plants, and other industrial applications. This product, combined with the successful TB(X)557 retractable sensor, TB(X)564 high pressure sensor, and the TB18 Safe-T-Clean valve allows ABB to address nearly any insertion sensor installation.
