Product Introduction
I. Functions of Ozone Sensor OZE 3-mA-2ppm, OZE 2-4P
OZE typeOzone SensorUsed for the determination of ozone in drinking water, swimming pool water, and process water of similar quality.
Measured Variable: Ozone
Application: Swimming pool water, drinking water, and process water of similar quality (free of surfactants)
Measurement Range: 0.02⋯2mg/l OZE 3-mA-2ppm Order No.: 79.29.57.8
0.1⋯3mg/l OZE 2.2-4P Order No.: 91.49.23.8
pH Range: Stable range for ozone
Temperature Range: 5-40°C (with temperature compensation) Maximum temperature change rate <0.3°C/min (no sudden temperature changes)
Maximum Pressure: 1 bar
Flow Rate: 30 l/h in DGM or DLGlll A/B type inline sensor housings
Not highly dependent on flow; typical signal increases by 15% when flow is twice the recommended value.
Break-in Period: 2-6 hours for initial operation; 1-3 hours for subsequent operation
1-3 hours after replacing electrolyte/membrane; 6 hours after cleaning the gold cathode
Membrane Cap Life: Standard one year (depending on water quality)
Electrolyte Life: Standard 6-8 weeks (depending on water quality)
Membrane Cap Material: Transparent PVC
Electrode Post Material: Black PVC or transparent PMMA (plexiglass)
Enclosure Protection: IP65
Supply Voltage: OZE3-mA: 16-24V DC
Output Signal: 4-20mA ≈0⋯133% of range
Cross Sensitivity: Chlorine <2%; chlorine dioxide interferes with measurement
Substances that reduce surface tension: e.g., surfactants, oil-clogged membranes (incorrect measurement)
Storage Temperature: 5-50°C
III. Electrical Connection of Ozone Sensor OZE 3-mA-2ppm, OZE 2-4P
OZE 3-mA-2ppm: Rotate the upper part of the sensor counterclockwise by 1/4 turn and remove it. Loosen
the fixing screw of the PG7 threaded connection and pass the 2-core cable through (4mmΦ, 2×0.25mm²).
(Important: Ensure that about 5cm of bare wire is left in the sensor). Then connect the two-core cable to the terminals
(1 = positive, 2 = negative). Press the upper part of the sensor completely into the housing and rotate clockwise to the
end. Tighten the fixing screw of the PG threaded connection. The OZE 3 sensor is now ready for installation.
Important: The sensor output signal is not electrostatically shielded.
OZE 2 – 4P: The sensor is connected to the corresponding measurement and control equipment, e.g.,
the 4-core lead of the DULCOTEST is connected to the OZWS (with 4-core connectors and moisture-proof threads on each side).
