4-wire PT100. The front cap provides a small cable feedthrough
where the cable of the external PT100 can penetrate the housing.
When closing the housing again, ensure that the solder points do
not get into contact to the aluminum housing.
NOTE: In order to minimize potential electrical noise coupling into
the external temperature sensor, the 4-wire cable should be
twisted and as short as possible. Cable lengths above 2m are not
recommended. For minimizing any noise further, the 4-wire cable
can be provided with an additional coaxial shield, which has to be
connected to ground.
