Installing IoT onto pre existing instrumentation

Shaun

Hi all,

I'm looking to see if someone can advise me about an IoT solution we are tring to implement. 

Presently, we have installed a Netvox 4-20mA sensor which is working to an extent however it can only read to the nearest 0.1 of a milliamp. This isnt overly useful as the device outputs data with much higher precision than that and we would need to be looking at the nearest 0.001 milliamp. 

Does anyone have experience with getting such precise readings on the IoT netowrk and if yes can you recommend a device which is capable of it. So far ive got in contact with a couple suppliers but the seem to be unable to help. 

Thanks!

    Hi, I would  suggest using an IoT device with a higher precision ADC. For a plug & play solution, check the Advantech WISE-4012 which has 4-20mA and 16-bit ADC resolution, so should achieve the precision you need. A higher percision solution is the ADS1256 HAT for the Raspberry Pi, which has 24-bit ADC. The drawback here is that custom programming would be needed and careful consideration of the wiring circuit. Best of luck, Eoin.
