I just sold a set like that to KIAI,I'd had since new,IMO I would not waste my time with wireless as one is only dealing with 4 lines and they work fine.
Not as expensive as it could be Thanks, I don't want to buy them only to find they don't work when they get here I have almost all the bits for my Scud project now.
No reason why they wouldn't work. You'd just have to make sure you put the correct scale under the appropriate wheel.
For what its worth; My calf cradle load cells were wireless, but my bull and maternity cradle load cells where hooked up by gold plated wire connections. Over time the wired readings werefar more accurate.
the wireless frequency these units operate at is the same as bluetooth and WLANs so in a "hostile" environment like the racetrack where MANY WLANs and 2.4Ghz kit is operating there is always the possibility of low-end wireless scales getting interference by people "violating" the max power output and upsetting the WPAN of the scales. They will work fine at home which is what the WPAN standard was meant for, if you're going to use them at the track then the wired scales are the go so long as they are RFI protected
doesn't make sense Dave, I would say the quality of the wired scales is better than the wireless scales ...... so long as you have a connection then the result comes down to the quality of the measuring device
Scott, the theory is that at the track there are so many 2 way radios and broadcasting units all running on different frequencys that the wireless units will always pick up a bit of interference, we also seem to have trouble with internet ect at the track too, my money would be spent on a hard wired set, thesignal on all these gadgets is only going to get stronger in the future so the interference is only going to get worse until the technology of the scales catches up, if you think back to early wireless computer networks they all had the same problem. The guy in the US may of upgraded the scales accordingly but the question is are you going to fly the prototype. ( an oompaloompa thats about a foot taller than me gave me that info)
Glen, by law the free wireless frequencies are not allowed to exceed 100mW in this country, it varies in other countries but 100mW is the max. I put in a LOT of the early autonomous wireless networks and the only problem I had in those days was bandwidth, 802.1a,b,g,n have developed into quite reasonable networks today but are still operating under the same scientific principles.
Ask a question and get a whole bunch of intelligent answers. Wow, don't see that often around these parts Thanks for the answers Gents, most helpful.
Thats why I emphasised the quality of the heavier weight set. Gold plated connections and much heavier weight range. I think the wireless transmitters and receivers tend to get lower quality as they try to price match.
You've probably already made up your mind, but to confirm , yes keep away from the wireless option. Spoke to my guy today as requested and he said they were hopeless, causes all sorts of problems at tracks. Even if only using at home you'll find the batteries will probably go flat on one scale meaning having to lift the car up to replace batteries and reset.
I haven't done anything yet, thanks for checking it out. I don't think there would be battery problems though as they say they will last a whole year.
