How do I display calibrated pressure readings in PSI on the LoopView Indicator connected to an NP640?
NP640 Pressure Transmitter with 0.25% Accuracy and Scaleable Output
I'm currently facing an issue with displaying calibrated values from an NP640 Pressure Transmitter on a LoopView Transducer Mount Loop Powered Current Indicator. Right now, the LoopView only shows values ranging from 0-9999, which are not in pressure units (PSI) as expected. I attempted to enable calibration through the configuration parameters, but this hasn't resolved the problem. My goal is to properly configure the LoopView device so that it clearly displays the readings from the NP640 Pressure Transmitter in PSI.

The LoopView can be scaled for engineering units which in your case would be PSI. In the LoopView configuration there are two parameters, in.LL which is the lower scaled value and in.HL which is high limit scaled value. For the NP640 in.LL should be set to 0 and in.HL to the upper range of the NP640 in PSI. You may also have to adjust your decimal point(dP.Po) depending on the range of your transducer. Feel free to contact IOthrifty for more assistance if you are still having difficulty.
