Two-Wire 4-20mA Two-Electrode Ozone Sensor For Drinking Water, Direct Drinking Water, Service Process Water

OZ1.2

Swimming pool water, drinking water, service water, process water
The water must not contain any surfactants (tensides)!

Electronic

Analog version: - voltage output

- analog internal data processing

- output signal: analog (analog-out/analog)

Digital version:    - electronic is completely galvanically isolated

- digital internal data processing

- output signal: analog (analog-out/digital)

or

digital (digital-out/digital)

mA-version:        - current output analog

- not galvanically isolated electronics

- output signal: analog (analog-out/analog)

Information about the

measuring range

The actual slope of a sensor can vary production-related between 65% and 150% of the nominal slope

Note: With a slope > 100% the measuring range is reduced accordingly.

(Ex.: 150% slope → 67% of the specified measuring range)

Slope drift

At repeatability conditions

(25 °C, pH 7,2 in drinking water)

Working temperature

Measuring water temperature: 0 … +45 °C

(no ice crystals in measuring water)

Temperature

compensation

Automatically, by an integrated temperature sensor
Sudden temperature changes must be avoided

Max. allowed working pressure

Operation without retaining ring:

- 0.5 bar

- no pressure impulses and/or vibrations

Operation with retaining ring in Flow cell:

- 1.0 bar,

- no pressure impulses and/or vibrations (see option 1)
