MINITRAC 31 • 4 … 20 mA/HART - four-wire

40447-EN-130430

Fig. 8: Level measurement - Residue detection on a storage tank

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 sufficient to maintain the max. ambient

temperature, you could consider using the water cooling system we

offer for MINITRAC 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.
