Not similar: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? will there be an improvement? 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 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 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 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 and foremost, the accuracy. The temperature limit, alternatively, indicates the min/max values between which the instrument may be operated without damage. With this particular, the instrument specifications don’t need 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 exemplory case of a pressure sensor: The instrument is supposed to deliver solid measured values at an ambient temperature selection of 0 ? 100 �C. At the same time, the sensor should never suffer any damage at ambient temperatures between -20 �C and 0 �C. In Caution , however, it does not need to provide accurate measuring results, or 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 specific measuring components, exhibit a comparatively large, often non-linear temperature error. Without further measures, a reliable pressure measurement would be impossible. Therefore, the manufacturer has to compensate for the temperature as a way to bring the error right down to an acceptable level. From an economic perspective, the limitation to a selected temperature range is practical, or is even absolutely necessary.
The distinction between temperature range and temperature limit applies to both the ambient temperature and the medium temperature. It is also 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 creates 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 is a better linguistic distinction. But, I have to admit, the answer is outside my ?range?.
