Any of them using the newest battery free technology cars have had for several years? (They work great)
I'd like a set of those with sensors that mount inside the tire.
I am curious what cars have a battery free sensor mounted inside the wheel? Only battery free system I have seen does not have sensors, they use the anti lock brake sensor at each wheel and count tire revolutions compared to the other tire. My Honda has this system but there is no sensor in the wheel. Only asking because I like to keep up with the new stuff and have not heard about this.
As far as TPMS for trailers go I have had the TST system with repeater running for years now and just upgraded to the new color monitor. I use it for the truck since my aftermarket wheels won't take the factory sensors and two trailers. I do recommend metal valve stems because I did have a rubber stem crack on my boat trailer. The only complaint I have is the new monitor has the temp and pressure reversed from the old style monitor so after years of looking at it one way it's backwards now and it takes some getting use to but that's just me I guess.
Our Challenger SRT has them and I would guess that other FCA products have them too. Also my friends Aston Martin is so equipped.
yes, there are a few out but they are AFAIK all using a larger inside the tire mount rather than being able to be used with a valve stem mount.
they use a piezoelectric SAW sensor and rquire a transmitter/reciever placed near each tire. TI has comercical offerings. transmitter/reciever and sensor is an RFID type device.
the nice thing for vehicle mfg is that it is designed to be used with the canbus system in the vehicle and doesn't need a seperate RF transmitter/reciever. so for a mfg it may be less costly than the current systems.
