TB4042 Toroidal Electrodeless Sensor
Brand: ABB GroupThe TB4042 conductivity cell expands the advancements in process conductivity measurement initiated by ABB with four-electrode conductivity measurement.
Unlike four-electrode sensors, toroidal sensors have no electrodes.
The TB4042 toroidal conductivity cell provides a means for measuring solution conductivity in chemically aggressive solutions that corrode, foul, or otherwise destroy, electrode-type sensors.
The sensor itself comprises two wound toroids encapsulated in a chemically resistant non-conductor made of polyetherether ketone (PEEK).
Measurement is made inductively via a magnetic coupling between the solution and the toroids.
Because measurement is made inductively and there are no electrodes that can be affected by erroneous resistances from foulants or coatings, these sensors are virtually impervious to all but thick layers of foulants.
Features- Greatly reduces coating and other fouling problems
- inductive measurement technique yields a solution conductivity measurement virtually unaffected by solution contaminants
- Multi-range capability
- measures from 400 µS/cm to 2,000 mS/cm
- Versatile mounting
- hardware for submersion, 1½ in In-line and low and high pressure ball valve insertion
- Automatic temperature compensator with fast thermal response
- Small size with large center bore
- enables 1½ in mounting, yet center bore is 50 % larger than comparatively sized sensors
- PEEK encapsulation
- assure chemical resistance and durability
- High pressure and temperature ratings
- up to 200° C (392° F), 2,070 kPag (300 psig) depending on mounting hardware and materials
- 316 stainless steel, Kynar®, titanium and CPVC hardware
