Not similar: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? is there a difference? My intuitive answer would be: Yes! The initial term describes a section and the next its border. On second glance, however, I have to conclude that both words ultimately express a similar thing with regards to temperatures: Range and limit are defined by a lower and upper value, for example 0 ? 100 �C. The relevant standard nevertheless defines a difference. Why?
IEC 61987 speaks of two different specification characteristics
The standard referred to is IEC 61987. This deals, among other activities, 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 which the instrument could 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 sense from a technical viewpoint. This could be illustrated by the following example of a pressure sensor: The instrument is supposed to deliver solid measured values at an ambient temperature range 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 does not have to provide accurate measuring results, or even 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 trusted pressure measurement would be impossible. Therefore, the maker has to compensate for the temperature as a way to bring the error right down to a satisfactory level. From an economic viewpoint, the limitation to a selected temperature range is practical, or is even essential.
The distinction between temperature range and temperature limit applies 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, compound gauge ราคา doubt if the normal user, without understanding of standards, understands it intuitively. Which inevitably results in the question of whether there is a better linguistic distinction. But, I must admit, the answer is outside my ?range?.
