5.8.1 Sensor Data
Memosens sensors provide relevant sensor data automatically.
Sensoface
The Sensoface icons provide the user with diagnostic information on wear and required maintenance
of the sensor. In measuring mode, an icon (happy, neutral, or sad smiley) is shown on the display to re-
flect the continuous monitoring of the sensor parameters.
You can configure the current outputs so that a Sensoface message generates a 22-mA error signal.

Behavior during Messages
The Sensoface message can also be output via a relay contact:

Note:
After a calibration, a smiley is always displayed for confirmation, even if Sensoface is disabled.
Adjusting Sensor Monitoring
01.
Open
Sensor Data
Sensor Monitoring Details
.
02.
Open a sensor parameter, e.g.,
ORP Offset
.
03.
Set
Monitoring
of the ORP offset to automatic or individual.
04.
If you select “Individual”: The nominal ORP offset and the min/max limits can be entered.
05.
In the
Message
menu item, select whether and how an exceeded limit is to be displayed:
Off
No message.
Failure
A failure message is shown in off-limit conditions; the corresponding NAMUR icon
is displayed.
Maintenance
A maintenance required message is shown in off-limit conditions; the corresponding NAMUR icon
is displayed.
06.
Set the sensor monitoring details for further sensor data such as sensor operating time or SIP
counter.
07.
Using the
left softkey: Back
, confirm the sensor monitoring settings and adjust further parameters.
or
Using the
right softkey: Back to Meas.
, confirm the sensor monitoring settings and end the func-
tion check (HOLD).
CIP/SIP Counters
Note:
CIP/SIP counters are available for the following pH sensor types:
SIP counter: Memosens pH, Memosens pH/ORP; CIP counter: Memosens pH/ORP
CIP/SIP cycles are used to clean or sterilize process-wetted parts in the process. Depending on the ap-
plication, either one chemical (alkaline solution, water) or several chemicals (alkaline solution, water,
acidic solution, water) are used.
• CIP temperature > 55 °C/131 °F
• SIP temperature > 115 °C/239 °F
The cleaning (cleaning in place) and sterilization (sterilization in place) cycles are counted to measure
the load on the sensor, e.g., in biotechnology applications.
