Bluetooth Transmitters (Pressure, Flow)
Bluetooth Transmitters (Pressure, Flow)
(OP)
Hi Everyone,
We are adding some additional piping to an existing facility, and need to install instrumentation. As this is an existing site, we are trying to avoid new wiring, and would like to use a wireless tranmisster (powered by solar panels).
We are investigating wireless transmitters (pressure and flow mostly) and are looking into "Bluetooth" tranmsitters. We are primarily interested in pressure and flows.
Has anyone used/bought/installed a blue tooth transmitter? What are your thoughts/experiences/concerns?
Thanks.

I believe most of the communication is in the 900-930Mhz operation, but I'm not sure what protocol this is.
Plus, if any of the instrumentation is used for control, I wouldn't recommend using wireless just yet. I'd stick with hardwiring. If the instrumentation is just for indication, wireless is great.

RE: Bluetooth Transmitters (Pressure, Flow)
Your are right. I think I read that the maximum distance for Bluetooth is about 25ft, which is sufficient for us to get the signal back to the local panel/RTU.
Have you used Bluetooth transmitters?

I would guess Modbus. Almost all of our remote sites on our SCADA system is Modbus.
Thanks though.

Specifically, I am interested in Bluetooth transmitters. Any personal experience there?
RE: Bluetooth Transmitters (Pressure, Flow)
My recollection of Bluetooth was as a wireless connection for a room in a house. For the PC market, Wi-Fi took the market for multiple rooms, etc.
Phoenix and many organizations offer wireless accessories to send a signal somewhere.

I regard the wireless stuff as suitable for monitoring but would need lots of experience before I used wireless for control.
I see Bluetooth on the web labeled as "Personal Area Networking".

We came across some info on Bluetooth transmitters. Since our distances is relatively short - about 20 ft - we are looking into this. Unfortunately, we can't recall where we seen it, and are now digging.
RE: Bluetooth Transmitters (Pressure, Flow)
I think I will leave Bluetooth alone for now, and just use wires.
