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 |
