Measuring Range Of The Temperature - Burkert 8223 Manuel Utilisateur

Example:
If the selected measuring range is: „0 to 10 mS/cm".
When the fluid conductivity measured by the sensor is < 2% of the full scale,
the 4-20 mA output delivers a 4 mA current; When the conductivity measured by the
sensor is equal to 10 mS/cm, the 4-20 mA output delivers a 20 mA current.
The curve hereunder shows the ratio between the measured conductivity and the
current value delivered by the 4-20 mA output.

When the conductivity exceeds the full scale by 10% (11 mS/cm in the example), the cur-
rent output delivers a 22 mA current. As soon as the conductivity is again equal or inferior
to the full scale value, the current output delivers a current between 4 and 20 mA.

3.2.2 Measuring range of the temperature

- The value of the temperature which corresponds to a 4-mA current is always -10 °C
- The value of the temperature which corresponds to a 20-mA current is always 80 °C
If the 8223 has been programmed to transmit the temperature (and not the con duc -
tiv i ty) on the 4-20 mA output (all SW2 switches are set to ON), the cor re spond ing
temperature/4-20 mA-output curve is the following:
The current output delivers a 22 mA current if the temperature is < -10 °C or > 80 °C.
