DULCOTEST® Sensors for Peracetic Acid

Peracetic Acid Sensor PAA 1-mA

This sensor measures peracetic acid without cross-sensitivity to hydrogen peroxide. It is designed for use in contaminated washing and waste water.

Operating limits

• pH range: 1.0 … 9.0 (peracetic acid stability range)
• Temperature: 1 … 45 °C
• Admissible temperature fluctuation: 0.3 °C/min
• Max. pressure: 3.0 bar (at 30 °C, in DGM)

Feed water

• Intake flow: 30…60 l/h (in in-line probe housing DGM or DLG III)
• Resistance to: Salts, acids, alkalis, surfactants, dirt films

Product water

• Measured variable: Peracetic acid, without cross-sensitivity towards hydrogen peroxide
• Selectivity: Peracetic acid selective towards hydrogen peroxide
• Cross sensitivity: Ozone, chlorine dioxide, chlorine, bromine

Electrical

• Supply voltage: 16...24 V DC (two-wire technology)
• Output signal: 4…20 mA ≈ measuring range, temperature-compensated, uncalibrated, not electrically isolated

Mechanical / hydraulic

• Measuring principle, technology: Amperometric, 2 electrodes, membrane-covered
• Diaphragm: Diaphragm-covered sensor, pore-free diaphragm
• Installation: Bypass: open sample water outlet
• Sensor fitting: DGM, DLG III
• Measuring and control equipment: D1C, DAC, AEGIS II

Measuring ranges

• PAA 1-mA-200 ppm: 1…200 mg/l
• PAA 1-mA-2000 ppm: 10…2,000 mg/l

Note: A mounting kit (order no. 815079) is required for initial fitting of the sensors in the in-line probe housing DLG III.

Application

• CIP (cleaning in place)
• Bottling
• Disinfection in pharmaceutical and medical technology
• Waste water treatment
• Scouring in Cleaning in Place (CIP), rinsers, also suitable in the presence of cationic and anionic tensides. The selective measurement of peracetic acid and hydrogen peroxide is possible.
