2.5 Operating range
Conductivity : 0 – 2000 mS/cm at actual process temperature.
Note: The sensor has an error (0.5 µS/cm for PEEK model, 1.0 µS/cm for PFA model) that
must be considered when application is chosen.
Temperature : -20°C to 130°C (-4°F to 266°F) for PEEK sensor
-20°C to 100°C (-4°F to 212°F) for PFA sensor
Pressure : 0 to 20 bar (0 to 290 PSIG) for PEEK sensor
0 to 10 bar (0 to 145 PSIG) for PFA sensor.
Note: At maximum process temperature the maximum pressure for the PFA sensor is 5 bar
(72 PSIG).
Cable length : max 50 meter, in combination with WF10 extension cable and
BA10 junction box

certified intrinsically safe circuit with the following maximum
values: Ui = 19.1 V; Ii = 170 mA; Pi = 0.8 W; Ci = 0 nF; Li = 0 mH

model IC200S series
Note: The effective internal capacitance Ci and the effective internal inductance Li of the
sensor are depending only upon the properties and the length of the connected cable.
Special conditions (X) : T6 for Tamb. -30°C to 40°C
T5 for Tamb. -30°C to 95°C
T4 for Tamb. -30°C to 130°C, depending on sensor body
material
: The sensor must be installed and used so, that dangers
of ignition due to hazardous electrostatic charges cannot
occur, especially in the case that the process medium is non-
conductive.
