Not the same: temperature range and temperature limit

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