Conductivity Cell TB457

The Conductivity Cell TB457 has 316 stainless steel body and integral Tri-Clamp fittings for use in sanitary services. The electrode tips and electrodes are sealed with Food and Drug Administration (FDA) approved silicone potting material. ABB offers two styles of these sensors to meet each particular need. The first is a flush face style that meets the process at the Tri-Clamp fitting. The second has an extended face designed to place the measurement electrodes into the process past the fitting. The extended face type is narrow enough to allow cleaning chemicals or steam to surround the electrode body thus insuring crevice free cleaning.

• Integral Tri-Clamp flange
• All FDA approved wetted materials
• Corrosion resistant stainless steel electrodes
• Extent of fouling notification and fouled sensor relay
• Integral automatic temperature compensators
• Suitable for all measurements: From ultrapure to concentrated solutions
• Maximum temperature 175 °C (347 °F)
• Maximum pressure 861 kPa (8.61 bar / 125 psi)

Conductivity Cell TB461

Ruggedly constructed of 316 stainless steel, the Conductivity Cell TB461 withstands the most demanding processes and measurement requirements. The TB461 insertion / submersion sensors (are easily installed into process lines and vessels by the 3/4 in. NPT insertion threads or submersed directly into fluids by the back-threads. TB461 hot-tap sensors are directly inserted and removed from lines and vessels without disturbing the process via either a 1-1/2 in. normal or 1-1/4 in. full port ball valve. This series is the most versatile offered by ABB. Full spectrum conductivity measurement is achieved by the wide rangeability of the sensor and the unique interchangeable tip design.

• Insertion, submersible and retractable models available
• Interchangeable and replaceable electrode tips
• Extent of fouling notification and fouled sensor relay
• Integral automatic temperature compensators
• Suitable for all measurements
• Inline / submersible max. pressure / temperature: 1,550 kPa (15.5 bar / 225 psi) at 200 °C (392 °F)
• Hot-tap max. pressure / temperature: 689 kPa (6.89 bar / 100 psi) at 200 °C (392 °F)
