any one out there collecting data from wireless sensors with 2130?
got a potential new client who wants to put accels on shaker screens, and was thinking wireless might be the go. as we know these things are notorious for wiring fatigue to standard accelerometers if not done properly

Contact Haver in Perth, they have a really good wireless setup with a tablet that's being trialed at some of the Pilbara sites. I argue that it's just another piece of kit to buy, but this one is worth it if you have plenty of screens. I don't have a contact for you but I'm sure you can ask around [smile]

I have seen the Haver equipment in action and compared it to the in house data collection we were doing with the 2130 and dual channel, phase and orbits. The Haver equipment was spot on and so much faster. I would definitely give the Haver system a trial.

Forgot to say the Haver system was for the screen motion and efficiency, it was not used on the screen gearboxes. Thats a total different ball game. What were you looking to do?

It is rare to find a wireless vibration monitoring system that provides analog outputs so that could in turn feed that analog output into a portable analyzer. Most systems take the digitized data at the receiver/gateway and send the digitized data to a network PC or web location. Here is one product that actually provides analog output that may interest you:
LORD MicroStrain’s WSDA® -Base -101 -LXRS® is a USB operated gateway with eight analog outputs that relay data collected from any sensors within its local network. http://www.microstrain.com/wireless/WSDA-BASE-ANALOG

I do not sell this product or have used it in the past.

Most wireless vibration sensors provide a dedicated permanent monitoring system, such as this one:

If you do find something that fits your needs please let us know what it is.

Yeah I should have mentioned that James, that system is only for screen motion [smile]

Nok are you using the CB512 Hyd armour cables? They are designed specifically for exciter monitoring..

Thanks Gents
I looked at the links + another local wireless sensor supplier, but none seem appropriate and appear more suited to static installations.

I'm looking at suspended Gyratory screens for sifting in flour milling, a whole different kettle of fish from what we've seen in the iron ore game. looking at motor and shaft bearings. motion monitoring not required.

Havent even got the client yet but meeting him on site soon and just wanted to give him options for his screens, garden variety accelerometers and armoured cable look the best option so far

is CB512 a CTC product?

Forgot to say we used this on a shuttle conveyor on a screen house. connected the 2130 to the BBC and collected the data. It worked great and detected a defect.

Hi James
The gvsensors is the local supplier i looked at, still has "onboard" cabling and bulky transmitter making it unsuitable for 900 rpm and 200 mm/sec

Hi Nok,
It's good for normal VA, but yes the screen would be too much. I would go for the Haver system for screen motion.

Hi Nok,

Have you looked into the SKF wireless system. I no it is not compatible with the 2130 but it looked like a good system to me. I have not tried it and don't know anyone who has.

We tried the Waites Wireless system here and it did not work. We were told it was because the cell phone signal is too week here at the mill.

That's too bad the Waites wireless wouldn't work for you. We are having some success with it.
