Ordering Information

Please choose one from each category to build your product number.
MODEL NUMBER 697C Fully encapsulated, non-indicating two-wire transmitter with 4-20mA output
MEASUREMENT PARAMETER (specify measuring scale) C1 Conductivity (from 0-5 to 0-20,000 µSiemens/cm)
E3 Electrodeless Conductivity (from 0-500 to 0-1,000,000 µSiemens/cm)
MOUNTING OPTIONS K Special
R Module mounted on metal plate for use with polycarbonate enclosure (NEMA 4X)
OUTPUT ISOLATION 0 Non-isolated output
1 1 Isolated output (Model 697C1 only)
NOTE: Isolated output option is not necessary for Model 697E3 because the process is electrically isolated from the transmitter, thereby making the output effectively isolated
N Standard
