Sensor monitoring

NOTE!
Sensor monitoring requires plant-specific empirical values for the sensor stress caused by process con-
ditions. Configure the sensor monitoring parameters on the basis of these empirical values.

Explanation
The linearization table for the measuring range concerned can
be activated/deactivated with this parameter. Linearization ta-
bles for JUMO digiLineCRcontain up to 30 value pairs in any
measurement characteristic line. Each value pair assigns a dis-
play value (Y-column) to a measured value (X-column). A linear-
ization table is available for every measuring range.
Linearization tables are created/edited using the JUMO DSM
software.
Explanation
only for hardwired device versions:
Activation of the temperature input
Optimization of measured value updating
The larger the value of the filter time constant, the slower is the
change in measured value at the output.
Correction value added to measured value
only for device versions with a separate sensor
Connection variants for the connected resistance thermometer
Explanation
Activates/deactivates the CIP/SIP alarm
on reaching the maximum number of CIP/SIP cycles
Activates/deactivates the sensor stress alarm
The "Sensor stress" value reflects the current level of stress on
the sensor from high temperatures and high conductivity val-
ues. The following sensor stress alarm states are signaled on
JUMO masters and on the device display (only on device ver-
sions with a display) on reaching the specified limit values:
• Pre-alarm for sensor stress above sensor stress level 3
• Alarm for sensor stress above sensor stress level 7
