LIQ-PDS-400
Reliable conductivity measurements for your process
With Rosemount 400 and 400VP 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 400 and 400VP contacting conductivity
sensors are ideal for use in clean, non-corrosive liquid having conductivity less than 20,000 μS/cm.
Rosemount 400/400VP 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 for direct screw-in insertion into
process piping using a front facing ¾ in. MNPT fitting.
Can alternatively be used with a pipe tee or flow cell in a
sidestream installation.
Offered with Variopol (VP6) quick disconnect fitting.

A Robust Two-electrode Design
The sensors have concentric titanium electrodes separated by
a PEEK insulator.
An EPDM O-ring seals the internal parts of the sensor from the
process liquid.
Available with a high temperature option up to 392 °F (200 °C)
with integral junction box.

Rosemount 400/400VP Contacting Conductivity Sensors
Ordering Information
The Rosemount 400/400VP Contacting Conductivity sensors are 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 or
Variopol (VP6) connector. Variopol cables sold separately (see accessories).
