Rosemount 400 / 400VP Endurance Conductivity Sensor
002821-HW-ROSE-021
Overview
The Rosemount Model 400 /400VP Endurance Conductivity Sensor are designed for direct screw-in insertion into process piping using a 3/4-inch MNPT fitting. The Model 400 sensors can also be used in sidestream samples. A 1-inch pipe tee with a 3/4-inch bushing is a suitable flow cell. A 3/4-inch pipe tee can be used with 0.1 and 1.0/cm cells. A transparent plastic flow cell is also available (PN 24091-02).

ENDURANCE sensors are contacting conductivity sensors. They are available in cell constants of 0.01, 0.1, 1.0, and 10/cm. The choice of cell constant depends on conductivity. High conductivity samples require larger cell constants. Consult the analyzer Product Data Sheet for recommended ranges and accuracy.
Sensors with 0.01, 0.1 and 1.0/cm cell constants have concentric titanium electrodes separated by a PEEK insulator. Viton O-rings seal the internal parts of the sensor from the process liquid. Sensors with 10/cm cell constants have graphite electrodes and an epoxy body.
