Rosemount™ 402VP Retractable Contacting Conductivity Sensor
Rosemount 402VP & 402 Conductivity Sensor
The Rosemount 402VP Retractable Contacting Conductivity Sensor provides accurate measurement of electrolytic conductivity in a broad range of applications from high purity water to clean cooling water.
This conductivity sensor is ideal for use in clean, non-corrosive liquid having less than 20,000 μS/cm.

Materials of Construction
Wetted Materials:
  • Electrodes: Titanium
  • Insulator: Glass filled PEEK
  • Body: 318 stainless steel
  • O-Ring: EPDM
  • Washer: Neoprene
    • All wetted surfaces have 15 micro in. (0.4 micrometer) Ra finish.

    Features

    • Conductivity sensor is designed to be retracted through a 1ΒΌ-in. ball valve assembly (sold separately)
    • Conductivity sensor may be removed from process piping without having to shut down or drain the line
    • Retractable design allows conductivity sensor to be removed from process piping without shutting down and draining the line
    • No initial calibration requirements; a factory-measured cell constant ensures out-of-the-box accuracy
    • Selectable cell constants 0.01, 0.1, and 1.0/cm cover a broad range of conductivity
    • Variopol (VP6) quick disconnect fittings
