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)

 Approx. <- 1% per month

Working temperature

Measuring water temperature: 0 … +45 °C

(no ice crystals in measuring water)
Ambient temperature: 0 … +55 °C

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
