entSensorThresholdRelation

This variable indicates the relation between sensor value
(entSensorValue) and threshold value (entSensorThresholdValue), 
required to trigger the alarm.  when evaluating the relation, 
entSensorValue is on the left of entSensorThresholdRelation, 
entSensorThresholdValue is on the right. 
              
in pseudo-code, the evaluation-alarm mechanism is:
              
...
if (entSensorStatus == ok) then
    if (evaluate(entSensorValue, entSensorThresholdRelation,  
        entSensorThresholdValue)) 
    then
        if (entSensorThresholdNotificationEnable == true)) 
        then
            raise_alarm(sensor's entPhysicalIndex);
        endif
    endif
endif
