Recommended Sensors for Conductivity
All Rosemount 400 series conductivity sensors (Pt 1000 RTD) and 410VP 4-electrode sensor.
Toroidal Conductivity (Codes
–
T)
Measures conductivity in the range of 1 µS/cm to 2,000,000 µS/cm (2 S/cm). Measurement choices
are conductivity, resistivity, total dissolved solids, salinity, and % concentration. The % concentration
selection includes the choice of five common solutions (0-12% NaOH, 0-15% HCl, 0-20% NaCl, and 0-
25% or 96-99.7% H
2
SO
4
). The conductivity concentration algorithms for these solutions are fully
temperature compensated. For other solutions, a simple-to-use menu allows the customer to enter
his own data. The transmitter accepts as many as five data points and fits either a linear (two points)
or a quadratic function (three to five points) to the data. Reference temperature and linear tempera-
ture slope may also be adjusted for optimum results. Two temperature compensation options are
available: manual slope (X% / °C) and neutral salt (dilute sodium chloride). Temperature compensa-
tion can be disabled, allowing the transmitter to display raw conductivity. For more information con-
cerning use of the toroidal conductivity sensors, refer to the product data sheets.
