A process isolation device for handling a process sensor probe at a process location fitting, characterized in that, the process isolation device comprises
- an adapter in said isolation device, said adapter being arranged in the process location fitting and being fitted for the process sensor probe to hold and move the sensor in at least three positions of the process sensor probe and so to switch between said three positions, the positions comprising the process sensor probe inserted position into the process location via the fitting into the process fluid, the process sensor probe retracted position from said processor location fitting and the process sensor probe pivoted aside position from said processor location fitting,
- push-pull means in co-operation with pivot means to push and pull the process sensor probe as attached to the adapter in co-operation to pivot the process sensor probe in said adapter.
