pH sensor series SC25V for connection to a
certified associated pH transmitter are used
for measurement of pH and temperature.
Ambient temperature range:
-40°C to +40°C for temp. class T6,
-40°C to +55°C for temp. class T4 and T5,
-40°C to +105°C for temp. class T3,
Electrical data
For the models without ID-chip the I/O
signals are from/to an associated intrinsically
safe certified pH transmitter (e.g. Yokogawa
transmitter Model FLXA21 series or
Yokogawa transmitter Model PH202S series).
For the models with ID-chip the I/O signals
are from/to an associated intrinsically safe
certified pH transmitter, Yokogawa Smart
Adapter Model SA11-P1.
Sensor input circuits:
In type of protection intrinsic safety Ex ia IIC,
only for connection to a certified intrinsically
safe circuit, with maximum values:
Ui=18 V; Ii=170 mA; Pi=0.4 W; Li=0 mH;
Ci=0 nF (without ID-chip)
Ci=0.4 nF (with ID-chip)
Special conditions for safe use:
For ambient temperature see above.
Electrostatic charges of the sensor enclosure
parts and label shall be avoided, especially
in the case that the process medium is non-
conductive. Use a damp cloth for cleaning
the equipment.
Note: When the sensor has been connected
to none intrinsically safe equipment
or equipment which exceeds the
restrictions regarding the sensor input
circuit, the sensor is not suitable for
intrinsically safe use anymore.
