operating temperatur

The operating temperature describes the optimal temperature or the optimal temperature range for the operation of electronic, electromechanical or mechanical systems, units or individual components of theirs.

Beyond the operating temperature, there is usually a lower degree of efficiency and (especially if overheating ) there is a risk of destruction. If a temperature interval is specified, it can also relate to absolute tolerance limits beyond which operation is excluded or there is a risk of destruction.

In DIN EN 60204-1, the ambient temperature is the temperature of the air or another medium in which the equipment is used as intended. It is part of the physical environmental and operating conditions, non-observance of which may exclude a warranty claim.

For manually operated devices in the consumer sector, care is usually taken to set the operating temperature in the range between room and body temperature .

Examples of optimal operating temperatures:

• Otto engines : 80 to 120 ° C

The cooling water, which heats up faster than the (crucial) engine oil, is usually measured. The pressure-tight closure of the cooler enables water temperatures of over 100 ° C.

• Commercially available NiMH batteries : −20 to 65 ° C
• Commercially available PC : 0 to 30 ° C ( temperature ranges of electronic components ).
