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 second its border. On second glance, however, I must 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 ? digital pressure gauge �C. The relevant standard nevertheless defines an improvement. 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 standard 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 that your instrument could be operated without damage. With this, 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 is often illustrated by the next example of a pressure sensor: The instrument is supposed to provide solid measured values at an ambient temperature selection of 0 ? 100 �C. Concurrently, the sensor must not suffer any damage at ambient temperatures between -20 �C and 0 �C. In this range, however, it does not need 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 would be impossible. Therefore, ไดอะแฟรม ซีล 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 pertains to both the ambient temperature and the medium temperature. Additionally it is useful 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 creates technical sense. However, I doubt whether 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 must admit, the solution is outside my ?range?.
