Behavior of the thermocouple
The integrated thermocouple has no direct contact to the liquid and is used to calculate the expansion
of the housing. The environment temperature has a big influence on the measured temperature of
the thermocouple. The response time of temperature changes is very high caused by the mounting
position of the thermocouple inside the housing.
Step-response time
Step-response time after a significant temperature change. (Filter „Off“)
