Introduction Introduction These operating instructions provide information on the technical data and functions of the DULCOTEST sensor for peracetic acid, type PAA 2 A3253 Fig. 1: DULCOTEST sensor for peracetic acid, type PAA 2 Sensor Order number PAA 2-3E-mA-20 ppm 1119538 PAA 2-3E-mA-2 ppm 1120263...
Introduction Functional description Brief description of the function Parameter Value Measured variable Peracetic acid (C Measuring range: 0.2 ... 20 mg/l pH-range: 5.5 ... 8.0 The sensor is a diaphragm-covered, amperometric three-electrode sensor. The sensor can be used to determine the concentration of peracetic acid in water. A platinum cathode acts as a working electrode and a silver halide-coated anode acts as a counter and reference electrode The peracetic acid contained in the sample water diffuses through the diaphragm.

Introduction Construction The sensor consists of 3 main compo‐ nents: the top part, the electrode shaft and the diaphragm cap. The diaphragm cap, filled with electrolyte, constitutes the measuring chamber, into which the meas‐ uring electrodes are immersed. The measuring chamber is sealed from the measuring medium by a microporous dia‐...

Safety NOTICE! Nature and source of the danger Damage to the product or its sur‐ roundings. Measure to be taken to avoid this danger. – Denotes a possibly damaging situation. If the situation is dis‐ regarded, the product or an object in its vicinity could be damaged.
Safety User qualification WARNING! Danger of injury with inadequately qualified personnel The operator of the system / equipment is responsible for ensuring that the qualifi‐ cations are fulfilled. If inadequately qualified personnel work on the unit or loiter in the hazard zone of the unit, this could result in dangers that could cause serious injuries and material damage.
Safety Training Definition Electrical technician An electrical technician is able to complete work on electrical systems and recognise and avoid possible dangers independ‐ ently based on his technical training and experience as well as knowledge of pertinent standards and regulations. An electrical technician must be able to perform the tasks assigned to him independently with the assistance of drawing documentation, parts lists, terminal and circuit diagrams.
(> 24 h). Intended use Intended use: Only use the sensor to measure and regulate concentrations of peracetic acid. Connection to external controllers requires the approval of ProMinent. The sensor is not a safety compo‐ nent.
Storage and transport of the sensor Storage and transport of the sensor Transport User qualification: instructed user Ä Chapter 2.2 ‘User qualification’ Only transport the sensor in its original on page 12 packaging and in compliance with the per‐ missible environmental conditions.
