I have got a datasheet of a pressure transmitter with Span and Cal Set under the heading Cal Range. The Span is mentioned as 100 - 2000 mbar and Cal Set is 0-200 mbar. Can this be possible as the calibration is outside of the span?
The end use max is within the allowable range of 100-2000 mbar, that part is okay. But you will have to check the accuracy over your calibrated range of 0-200 mbar.
The low end pressure transmitters are typically a tough measurement in an operating plant, so you often settle on what is available for the cost, but it is wise to check it.
It is likely interpreted like this:
The possible ranges can use spans from 100-2000 mbar.
That means ranges can be from 0-100 mbar up to 0-2000 mbar
A range of 0-200 mbar falls within the usable turndown range of the device.
