Not similar: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? will there be 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 the same thing in relation 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 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 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 may be operated without damage. With this, the instrument specifications do not have to be adhered to at all.
What may sound a bit pedantic, makes perfect sense from a technical point of view. This can be illustrated by the following example of a pressure sensor: The instrument is meant to provide solid measured values at an ambient temperature selection of 0 ? 100 �C. At the same time, the sensor must not 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 trusted pressure measurement will be impossible. Therefore, the manufacturer must compensate for the temperature as a way to bring the error 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 applies to both ambient temperature and the medium temperature. Additionally it is useful for other specification characteristics, for instance overpressure.
Conclusion
Yes, you will find 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 results in the question of whether there exists a better linguistic distinction. But, I must admit, the solution is outside my ? Worry ?.
