CCS120 Operation Operation Sensor design a0006354 Fig. 7: Sensor design Membrane cap Thread NPT 3/4" Sensor shaft TOP68 plug Measuring principle The amperometric sensor is based on the conversion of the measuring variable chlorine in electrical current. Two electrodes covered by an electrolyte are in contact to the medium via a membrane. -
Page 14: Electrolyte Fill In
Operation CCS120 Electrolyte fill in Warning! Do not swallow the electrolyte. Avoid contact of the electrolyte with skin and eyes. Otherwise wash with a lot of water. In case of eye inflamation, contact a doctor. " Caution! • Do not touch or damage the membrane or electrodes. - Page 15 CCS120 Operation Perform the following steps to fill the membrane cap with electrolyte: Open the electrolyte bottle and screw on the nozzle. Squeeze out excess air. Place the electrolyte bottle completely onto the membrane cap (Fig. 8). Slowly squeeze the electrolyte out of the bottle in one steady stream, while continously retracting the bottle.

Page 16: Commissioning
Commissioning CCS120 Commissioning Note! • Read also the instructions for operation and commissioning in the operating instructions of the transmitter. • The power supply to the transmitter and to the sensor must not be interrupted. If the power supply is interrupted (> 2 hours) the sensor must be re-commissioned (polarisation time). - Page 17 CCS120 Commissioning Requirements The sensor reading is stable (no drifts or unsteady values for at least 5 minutes). This is normally fulfilled, when: • The polarisation period is finished. • The flow is constant and within the correct range. • The sample medium and the sensor are at the same temperature.
