temperaturkoder

Temperaturkoder are symbolic labels used to describe temperature conditions without reporting exact degrees. They are employed in meteorology, logistics, manufacturing, and building automation to simplify communication, feed control systems, and document compliance. A temperaturkod can be numeric (1–5), alphanumeric (T1–T5), or a simple set of letters (C for cold, N for normal, H for hot). Each organization defines a legend that maps codes to temperature ranges or states, and there is no universal standard.

In practice, a temperaturkod serves several purposes: it compresses information for quick human reading, enables automated decision rules in controllers, and standardizes reporting across teams and devices. For example, a transport company might use T1 for temperatures below -20°C, T2 for -20°C to -5°C, T3 for -5°C to 5°C, T4 for 5°C to 20°C, and T5 for above 20°C. In weather services, codes may represent temperature bands used in alerts or forecasts. In industrial processes, codes indicate operating states or setpoints rather than exact readings, which can trigger safety interlocks or alarms.

Implementation typically involves defining the code set, its ranges, and the intended action for each code; publishing a legend in user manuals; and integrating the codes into data logs and alarms. Limitations include ambiguity between nearby values and the need for country- or industry-specific conventions.
