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 predifined 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:)
