Temperature Development of C2 Series after Power-Up 
This section gives information about the temperature development of C2 series after power-up. A 
total of three temperature measurement cases are shown and compared. 
The first case indicates the development of internal temperature and external housing temperature 
after power-up without any additional mounted heat sink. This case is very unlike, because in most 
industrial applications the C2 sensor is mounted on a heat conductive carrier (e.g. metal plate), which 
works as a heat dissipater. The operation of C2 sensor without any metal plate (e.g. during evaluation 
and/or testing in laboratory environment), requires the mount of a heat sink on the housing. 
The other two cases show the temperature development after power-up with one and two mounted 
heat sinks. In all test cases the ambient temperature was 22 °C.
