ABB TB556.1.3.1.15.T.05 pH/ORP Sensor

Overview

ABB TB556.1.3.1.15.T.05 is a genuine ABB TB556 series Kynar-body pH/ORP (redox) sensor, engineered for continuous in-line water quality monitoring in demanding industrial process environments. Renowned for ruggedness, longevity and measurement accuracy, the TB(X)5 sensor family from ABB outperforms conventional glass-bodied sensors in aggressive chemical dosing, wastewater and process water applications, making the ABB TB556.1.3.1.15.T.05 a preferred choice for plants that cannot tolerate frequent sensor replacement or calibration drift.

As the official authorized partner and exclusive regional representative for ABB, Seven Star LLC proudly supplies genuine ABB TB556.1.3.1.15.T.05 pH/ORP sensors to industrial plants throughout Oman and the GCC. Every sensor shipped from our Muscat-based facility is sourced directly through ABB’s authorized distribution channel, ensuring authentic Kynar body construction, correct glass electrode chemistry and full compatibility with existing ABB AX400, AW500 and AWT series analyzer transmitters already installed across regional water treatment and process facilities.

Measurement Principle

The ABB TB556.1.3.1.15.T.05 measures pH or oxidation-reduction potential using a glass measuring electrode paired with a reference electrode, both housed within a chemically resistant Kynar (PVDF) body. When immersed in process liquid, the glass membrane develops a small electrochemical potential proportional to the hydrogen ion activity of the solution, which is compared against the stable reference electrode potential to generate a millivolt signal that the connected analyzer converts into a calibrated pH or ORP reading.

Because the sensing element relies on electrochemical equilibrium rather than mechanical or optical measurement, the TB556.1.3.1.15.T.05 delivers fast response times and stable readings even in fouling-prone or chemically aggressive process streams. The Kynar body construction resists attack from acids, caustics and oxidizing chemicals encountered in dosing, neutralization and effluent treatment applications, extending sensor service life well beyond that of standard glass or epoxy-bodied alternatives and reducing the frequency of costly sensor replacement.

Engineering Design of the ABB TB556.1.3.1.15.T.05

The sensor combines a precision glass pH or ORP measuring element with ABB’s solid-state Next Step reference cell, both integrated into a rugged Kynar housing that resists cracking, swelling and chemical attack under continuous submersion. The 3/4 in. NPT process connection fits standard insertion assemblies, flow chambers and submersion holders, allowing straightforward retrofit into existing ABB sensor housings without piping modification.

Electrical connection is made via a shielded, low-noise cable terminated for direct interface with ABB AX400, AW500 series analyzers, with cable length and connector configuration selected to match the specific installation. The sensor is rated for continuous immersion service across typical process water temperature and pressure ranges, and its design supports both submersion and flow-through insertion mounting configurations commonly used in water treatment and chemical dosing skids.

Reference System and Process Ratings

The ABB TB556.1.3.1.15.T.05 uses ABB’s solid-state Next Step reference, in which the potassium chloride (KCl) electrolyte sits in a solid inner chamber rather than a refillable liquid reservoir, contacting the process through a wood or PTFE junction in flush or notched style. Sealing to the process line is by external O-ring, offered in Viton, EPDM, silicone or Kalrez to suit solvents and strong oxidisers, and temperature compensation is integral, with 3 kΩ Balco and Pt100 variants alongside an uncompensated build for redox duty. ABB rates the series for 0 to 100 °C and 690 kPa (100 psi) at 80 °C, an envelope that covers typical Gulf water treatment line conditions.

The 3/4 in. NPT process connection and insertion depths from 27.9 mm to a maximum of 127 mm let the sensor be set at the correct immersion depth in pipe tees, flow chambers and open tanks without adapters, and the factory-potted cable — 1.5 m (5 ft) as standard, to 9 m (30 ft) on request, terminated as BNC or tinned pin leads — removes a common ingress path in wet installations. Buyers cross-referencing part numbers should note that the TBX556 variant, unlike the TB556.1.3.1.15.T.05, carries a solution ground rod in 316 stainless steel, titanium or Hastelloy B2 for glass- and reference-impedance diagnostics, so plants specifying predictive electrode diagnostics must confirm which body style their analyzer expects.
