I was given Rosemount 3051L to calibrat and install to measure the pressure.
The range of this diaphragm pressure transmitter is 0 - 250 kPa.
Span is 60 - 80 kPa.
This was what I did:
- Re-range using HART communicator (Beamax). I set URV= 80 kPa & LRV=60 kPa
- Error set to 1.5 % of Span.
The calibration passed. However, I was not satisfied about this result as this I think will definitely have a great impact on production…but this was what the guys here have been using… The turn down ration of this transmitter is 10:1 that makes the minimum span to be 25kPa, where as the span of this measurement is 20kPa.
I therefore would like to change out the existing installation and change with a different one that will be more suitable to the process.
Anybody having any idea as to what I will need to do?
Has anyone ever come across this issue before?
Thank you for your time.
