The pH value requires temperature compensation for two reasons:
1. Temperature effect of the electrode:
The electrode slope is dependent on the temperature. Therefore this effect must be
compensated for temperature changes
(
Temperature compensation
, see below).
2. Temperature effect of the medium:
The medium pH value is also temperature dependent. For high-accuracy
measurements, the pH value related to temperature can be entered in table form
(
Medium temperature compensation
, see below).
Temperature compensation
ATC: Automatic temperature compensation: The medium temperature is measured with
a temperature sensor. This temperature is used via the temperature input in the
Mycom S CPM 153 to adjust the electrode slope to the medium temperature.
MTC: Manual temperature compensation: This is advisable in processes which run at a
constant temperature. Here, you enter the temperature value manually, which is used to
adjust the slope of the electrode to the medium temperature.
MTC+Temp.: The pH value is corrected with the manually entered temperature (see
MTC). On the display however, the value which appears is what the temperature sensor
measures in the medium.
F5 Steady contact
Wiping contact
Contact type: fault signalling contact
(only, when NAMUR function = off)
Steady contact
= Active for as long as an error is
present.
Wiping contact
= Active for 1 second when an alarm
signal occurs
E1
F6 ChemoClean is always a
NO contact. Note in display
(only when the full ChemoClean function is selected
in Field F1, which means CCC and CCW)
With the ChemoClean function, the valves of injector
CYR 10 are effected with a NO contact.
