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've had similar issues in the past as most LoRaWAN/NB-IoT native devices don't provide the needed accuracy for 4-20mA.

    I heard good things about Aircom but I haven't tested the 4-20mA yet.

    What I've done in the past is introduce a PLC which has a more higher ADC resolution, and then organised the data into modbus registers. From this I can query up to 32 registers using a Milesight UC300 polled every 5 minutes (under SF10 on LoRaWAN). This can be a good work around in an industrial environment where you may want to connect other instrumentation.
