TCML N(-S) Overview Overview The TCML N(-S) is a membrane-covered, amperometric sensor for the determination of total chlorine. Structure Pg7 screwed connection (in the TCML N-S screw/plug connection for connecting cable AK-CL) Shaft Sensor element Counter electrode O-ring 14 x 1,8 Reference electrode Electrode finger Measurement electrode... - Page 5 TCML N(-S) Overview required. Routine calibration is done by comparison with the photometric DPD method according to DIN 38408. The TCML N sensor is connected with the monitor (e.g. MULTILINE 1000) via a Electrical connection two line connection. The wires are used for the power supply of the monitor and TCML N for the transmission of measurement signals (4 - 20 mA current signal).

TCML N(-S) Commissioning CAUTION Overpressure in the membrane cap can destroy the membrane disk. Therefore, make sure the valve opening is not inadvertently closed by your fingers. Excess electrolyte solution must be able to escape freely at any time. Screw slowly so that no back pressure can develop. Using a blunt object, slide the hose ring over the valve opening and insert it evenly in the groove. - Page 11 TCML N(-S) Commissioning Slide in and position the sensor. For the optimum measuring position align the following parts of the sensor flush with the top edge of the lock nut: TCML N: The bottom edge of the groove on the connecting head. ...
