Not the same: temperature range and temperature limit

Temperature range and temperature limit for pressure sensors ? is there a difference? My intuitive answer will be: Yes! The initial term describes a section and the second its border. On pressure gauge 10 bar , 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 also include 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, on the other hand, indicates the min/max values between which the instrument may 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 perfect sense from a technical perspective. This could be illustrated by the following example of a pressure sensor: The instrument is meant to deliver 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, as well as measure.
The difference between temperature range and temperature limit is plausible
This sounds paradoxical at first, but is plausible on closer inspection. Pressure sensor elements, i.e. the actual measuring components, exhibit a comparatively large, often non-linear temperature error. Without further measures, a reliable pressure measurement will be impossible. Therefore, pressure gauge octa has to 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 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 example 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 you will find a better linguistic distinction. But, I must admit, the solution is outside my ?range?.
