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 initial term describes a section and the second its border. On second glance, however, I must 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 instance 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 also include 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 particular, the instrument specifications don’t need to be adhered to at all.
What may sound a little pedantic, makes sense from a technical perspective. This could be illustrated by the next example of a pressure sensor: The instrument is meant to provide solid measured values at an ambient temperature range of 0 ? 100 �C. At diaphragm seal , the sensor should never suffer any damage at ambient temperatures between -20 �C and 0 �C. In this range, however, it generally 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 comparatively large, often non-linear temperature error. Without further measures, a trusted pressure measurement will be impossible. Therefore, เกจวัดแรงดัน must compensate for the temperature so that you can bring the error right down to a satisfactory level. From an economic perspective, 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. It is also useful 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 results in the question of whether you will find a better linguistic distinction. But, I must admit, the solution is outside my ?range?.
