Rosemount™ 400 Contacting Conductivity Sensor

Rosemount

With the Rosemount 400 general purpose 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 sensors are ideal for use in clean, non-corrosive liquid having less than 20,000 ?S/cm.

Features

  • 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
  • The sensors are designed for direct screw-in insertion into process piping using a front facing 3/4 inch MNPT fitting
  • Can alternatively be used with a pipe tee or flow cell in a sidestream installation
  • Offered with Variopol (VP6) quick disconnect fitting
  • 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
