On vessels with temperature insulation, the sensor and the source

container should be preferably mounted outside of the tank insulation.

cut-out in the tank insulation for mounting the sensor and the source

container. Make sure that the max. ambient temperature of the sensor

is not exceeded.

If the max. ambient temperature is exceeded, you must take suitable

measures to protect the instrument against overheating.

You can protect the instrument by providing a suitable insulation

against the heat or mounting the instrument further away from the

heat source.

Make sure these measures are taken into account already in the plan-

ning stage. If you want to carry out such measures later on, contact

our specialists to ensure that the accuracy of the application is not

impaired.

Ifthesemeasuresarenotsucienttomaintainthemax.ambient

temperature, you could consider using the water cooling system we

oerforSOLITRAC31.

The water cooling must also be included in the calculations for the

measuring point. Contact our specialists regarding the dimensioning

of the water cooling.
