Code: FC1 membrane sensor
Product name: FC1 membrane sensor for total chlorine measurement

The Wallace & Tiernan® total chlorine measurement module can be used with either the SFC electronic package for single point analysis and control or the versatile MFC electronic package for multiple measurements and control.

 General
The Wallace & Tiernan® total chlorine measurement
module can be used with either the SFC electronic
package for single point analysis and control or
the versatile MFC electronic package for multiple
measurements and control. It consists of a plug-in
sensor card and a membrane-type sensor probe that
can be mounted in a variety of flow cells. Total
chlorine is the sum of free and combined chlorine
and occurs when ammonia or organically bound
nitrogen is present in the treated water to from
chloramines. The sensor features reagentless
operation with a standard measuring range from
0.05 to 20 mg/l.
Typical applications
n Measurement and control in industrial and
municipal water treatment
n Process measurement, final inspection and
testing, neutralization plants
n Monitoring of potable water, well water,
pool water as well as other clean water
applications where a total chlorine residual
measurement is required
Features
The total chlorine measurement sensor consists of a
membrane-covered potentiostatic 3-electrode system
with an integral temperature sensor for temperature
compensation between +5 and 45 °C (41 and 113 °F).
Zero point calibration is not necessary. An internal,
buffered electrolyte reduces the effect of pH eliminating
external pH buffering or pH compensation.
The sensor is supplied with a 0.9 m (3.0 ft.) screened
coaxial cable. Extension cables up to 50 m (164 ft.) in
length are available as optional accessories. Utilizing
“plug and play” technology allows the SFC or MFC
controller to automatically recognize the sensor card
and provide the correct display information. An
analog output (0/4 to 20 mA) is available along with
user configurable alarm contacts.
