Hello,
I have a confusion in defining calibration range.
As far as i know calibration range is defining ranges for which corresponding 4 mA or 20 mA should be generated for a given sensor. Is this correct?
When comes to my work i am doing data sheets for field instruments in my datasheets like pressure transmitter and temperature transmitter there are fields like:
Range Limits
Calibration Range
i will define range limits my considering Max operating Pressure/Temp that will come to 66 % of the desired range.i am clear about range limits.
but for defining calibration range i am not clear. when i made little research on internet some said Min Operating pressure/Temp and Max operating pressure/Temp will be calibration range. But i feel this not clear because some people contradicted this.Please clarify me regarding this calibration range.
To add about temperature transmitters, i am using both RTD's and Thermocouple's for my application. when i interacted with some vendors they said there is no use of defining any calibration range at all for temperature sensors as everything is predefined in the form of table's and said calibration range is needed only for pressure sensors and other sensors other than temperature sensors.
But some vendors are contradicting this statement.
i am now totally confused in defining calibration range. If to define please guide me how to decide calibration range with respect to sensors application (Pressure, Temperature, Flow etc).
Please help me as soon as possible.
Thanks in advance
