Not the same: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? is there a difference? My intuitive answer would 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 a lower and upper value, for instance 0 ? 100 �C. The relevant standard nevertheless defines a difference. Why?
IEC 61987 speaks of two different specification characteristics
The standard described is IEC 61987. This deals, among other things, with the properties of fluid sensors, which also include pressure sensors. With ?range? and ?limit?, the typical 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 which the instrument could be operated without damage. With this particular, the instrument specifications do not have to be honored at all.
What may sound a little pedantic, makes sense from a technical perspective. This could be illustrated by the following exemplory case of a pressure sensor: The instrument is meant to deliver solid measured values at an ambient temperature range of 0 ? 100 �C. Simultaneously, 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, as well as 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 specific measuring components, exhibit a relatively large, often non-linear temperature error. Without further measures, a trusted pressure measurement will be impossible. Therefore, the maker has to compensate for the temperature so that you can bring the error down to a satisfactory level. From an economic viewpoint, 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 is a difference between range and limit in the normative world of pressure sensor technology. And yes, it makes technical sense. However, I doubt if the normal user, without knowledge of standards, understands it intuitively. Which inevitably leads to the question of whether you will find a better linguistic distinction. But, I have to admit, the solution is outside my ?range?.
