Rosemount™ 402VP Retractable Contacting Conductivity Sensor
rosemount 402 and 402vp sensor
With the Rosemount 402VP retractable conductivity sensors, you will be able to accurately measure electrolytic conductivity in a broad range of applications from high purity water to clean cooling water.
The Rosemount 400 sensors are ideal for use in clean, non-corrosive liquid having less than 20,000 μS/cm.
Rosemount™ 402VP Retractable Contacting Conductivity Sensor


Ambient Temperature
32–212 °F (0–100 °C)
Cable length (Model 402 only): 10 ft (3.1 m). For longer cable length, choose option -60 (integral junction box) and order interconnecting cable separately.


  • Retractable design allows sensor to be removed from process piping without shutting down and draining the line
  • Rugged construction: Titanium electrodes with 316 stainless steel insertion tube and PEEK insulator
  • 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
  • Comes with Variopol (VP6) quick disconnect fitting.
