Reliable conductivity measurements for your process

With Rosemount 402 and 402VP contacting 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 402 and 402VP contacting conductivity
sensors are ideal for use in clean, non-corrosive liquid having conductivity less than 20,000 μS/cm.

Rosemount 402/402VP Contacting Conductivity Sensors

Overview

Minimize Start-up and Installation Time

 A factory-measured cell constant ensures out-of-the-box

accuracy and no initial calibration requirements.

 Available in cell constants of 0.01, 0.1, and 1.0/cm.

Meet Your Process Mounting Needs

 The sensors are designed to be retracted through a 1¼ in. ball

valve assembly (sold separately).

 Sensors may be removed from process piping without having

to shutdown or drain the line.

 Offered with Variopol (VP6) quick disconnect fitting.

Rosemount 402/402VP Contacting Conductivity Sensors

Ordering Information

The Rosemount 402 Contacting Conductivity sensor is intended to measure
electrolytic conductivity in clean water applications. These sensors can be configured
with either a 0.01/cm, 0.1/cm, or 1.0/cm to accommodate varying levels of
conductivity. The sensors are available with either an integral cable connection (402)
or Variopol (VP6) connector (402VP). Variopol cables sold separately (see accessories).
