Model 225, 226, and 228: Toroidal Conductivity Sensors

Source: Emerson

The Model 225, 226, and 228 toroidal (inductive) conductivity sensors consist of a pair of wire-wound metal toroids overmolded with corrosion-resistant PEEK or Tefzel. One coil is the transmitter, and the other coil is the receiver.

Use Rosemount Toroidal Conductivity Sensors in liquids where sensors with metal electrodes would corrode or become fouled.

The Model 225, 226, and 228 toroidal (inductive) conductivity sensors consist of a pair of wire-wound metal toroids overmolded with corrosion-resistant PEEK or Tefzel. One coil is the transmitter, and the other coil is the receiver. When the sensor is immersed in a conductive liquid and the transmitter coil is energized, the coil induces a current in the solution. The solution current induces another current in the receiver coil, which the analyzer measures. The current in the receiver coil is directly proportional to the conductivity of the solution.

Features

  • NON-CONTACTING (TOROIDAL) SENSORS resist corrosion and fouling.
  • SENSORS ARE IDEAL for measuring concentrations of acid, base, and salt solutions.
  • A VARIETY OF MOUNTING CONFIGURATIONS ARE AVAILABLE: submersion, immersion, and flow-through.
  • SENSORS ARE COMPATIBLE with most Rosemount Analytical toroidal conductivity analyzers.
  • MODEL 225 SENSOR AVAILABLE in unfilled PEEK and USP Class VI unfilled PEEK. Sensor meets 3A sanitary standards.
