Seems as though I'm loaded with questions these days.
Outfitting a new RV is exciting and with the help of RV Net members I am able to make much better choices. We had a tire pressure monitor for our fifth wheel..each wheel had a sender and the monitor was in the cab...I had all truck wheels and RV wheels monitored. It worked well...it's the one thing I didn't sell when I sold the RV. I've been using in on my car. Here's the situation: it's time to replace the batteries in the sending units. You send the unit in to the company in Arizona and get a new one...at a reduced rate.
Are there any units available that can remotely monitor tire pressure without having a sending unit on the tire. Sounds screwy, and it may very well be. I'm curious!

No. There must be some sort of sending unit for each tire.
Perhaps, though, you asked the wrong question? Are you looking for after-market TPMS where the tire pressure sensor need no batteries? That is technically possible given the available energy from tire rotation.
Search the internet for batteryless TPMS and you will find some, but they may not be suitable.
Yes, but testing so far has not been encouraging. One type mounts on the fender and checks the aspect ratio of the tire for change. As I've read, many problems surfaced, such as keeping them clean, and folks like Pressure Pro build such a good product it is not felt they can compete. There was also a unit produced that used the ABS and computer to watch for differences in the rpm of the wheels. Seemed promising, but manufacturers would need to add it to their computers, something they aparently didn't want to do. Much easier to meet government meddling using a sensor strapped inside the tire.
I'm sure other types exist that I've not read about.
When my Pressure Pro sensors need new batteries, which so far has been unneeded in 6 years, it only costs $30 each to exchange. I'm happy.

The ABS technology is being on cars, our '03 Ford Windstar has it. But I don't think it would work on duels unless both duel tires went down.
I've had the light come on indicating a soft tire on the car. And looking at the tires I can't tell which tire is soft, only with a tire pressure gauge can I tell which tire is soft.
I carry a hand held radiant thermometer and check for high tempter. I've often wondered if that could be built in the fender well, and have a remote read out in the cab?
