Not the same: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? is there a difference? My intuitive answer will be: Yes! The first term describes a section and the second its border. On second glance, however, I have to conclude that both words ultimately express the same thing with regards to temperatures: Range and limit are defined by way of a lower and upper value, for example 0 ? 100 �C. The relevant standard nevertheless defines an improvement. Why?
IEC 61987 speaks of two different specification characteristics
The standard referred to is IEC 61987. Professional deals, among other things, with the properties of fluid sensors, which likewise incorporate pressure sensors. With ?range? and ?limit?, the typical designates two different specification characteristics. Accordingly, the temperature range describes the span in which the instrument specifications must apply ? first of all, the accuracy. The temperature limit, alternatively, indicates the min/max values between that your instrument may be operated without damage. With this particular, the instrument specifications don’t need to be honored at all.
What may sound a bit pedantic, makes sense from a technical viewpoint. This is often illustrated by the next example of a pressure sensor: The instrument is supposed to provide solid measured values at an ambient temperature range of 0 ? 100 �C. As well, the sensor should never suffer any damage at ambient temperatures between -20 �C and 0 �C. In this range, however, it does not have to provide accurate measuring results, and even measure.
The difference between temperature range and temperature limit is plausible
This sounds paradoxical initially, but is plausible on closer inspection. Pressure sensor elements, i.e. the actual measuring components, exhibit a relatively large, often non-linear temperature error. Without further measures, a reliable pressure measurement would be impossible. Therefore, the maker has to compensate for the temperature to be able to bring the error right down to an acceptable level. From an economic perspective, the limitation to a selected temperature range makes sense, or is even absolutely necessary.
The distinction between temperature range and temperature limit pertains to both ambient temperature and the medium temperature. Additionally it is used for other specification characteristics, for instance overpressure.
Conclusion
Yes, there exists a difference between range and limit in the normative world of pressure sensor technology. And yes, it creates technical sense. However, I doubt whether the normal user, without knowledge of standards, understands it intuitively. Which inevitably results in the question of whether there is a better linguistic distinction. But, I must admit, the solution is outside my ?range?.
