Recently, I was thinking about buying a universal tyre pressure and temperature control system. Some are sure that this thing is completely useless: it is much easier to take the usual manometer and to manually measure the pressure or to determine whether everything is in order with wheels. I've decided to trust the technique so that I don't have to test it manually and not to test it. It is not realistic to define a 30% wheel (who in doubt-try it on your own, I assure you that it can only be guessed).
And with such a system, I can control the pressure and temperature in the tyres at any time. This is especially true during long trips, and it will not be in the way of everyday driving around the city. However, the price of the question (if the cost of the system is distributed at all times) is not so great-about $200. Having weighed all for and against, I decided that the pressure and temperature control system in the tyres would be better, and the main thing is more calm than without it. The choice fell on the system of the company Carax TPMS CRX-1002 with external sensors.
Here's what the system looks like (taken from the manufacturer's site for visibility):
1. TPMMS CRX-1002-1 unit-1 unit (small compact monitor).
2. Power wire from the cigarette lighter receptacle is 1 unit. (I don't actually use it at all, because the monitor can work on batteries).
3. TPMMS CRX-1002-4 wheel (Serial):
4. LCD-LCD-display attachment and mount seat pan on a windscreen-1 unit (very easy to use, the monitor is easy to catch and is removed).
5. Device to prevent theft of wheel transducers-1 unit (ring and tab).
6. AAA Battery battery (I bought the batteries and I already forgot the last time I loaded them).
7. Lithium cells CR1632-4 pieces (normal "tablets").
8. Operating manual-1 unit (written in Russian, in plain language).
System summary:
-Signal if tyre pressure drops or exceeds programmed indicators;
-Pressure and temperature metrics in the wheels are continuously displayed on the monitor display, and can be seen at any time;
Continuous monitoring of tyre pressure;
-It has an extremely easy way to install.
There is a similar model (TPMMS CRX-1001), which is no different from this (the only difference is that the sensors are not external, but internal). Really, it's $15 more expensive, but it's not a matter of principle.
In fact, this is how it looks in reality:
A box.
Off. The device has a G-sensor that saves the battery power. It activates the device only after a small vibration, that is, enough to get in the car.
Then, after the power on, the connection is established between the parent device and each sensor.
This is what it looks like when all the sensors were found and connected (no more than 2 minutes).
All the sensors are connected and pressured.
You can see the temperature in each wheel (by pressing the thermometer button)
Everyone, after that, we can go! During the trip, the pressure and temperature will naturally increase.
Well, the last thing about installing the sensors.
Here's the transducer looking at the wheel:
It is installed and removed using a hexagonal key. The protection against the fool, of course, but the young hooligans in the yard will not be reduced. There is no point in stealing because all the sensors are serial and reprogrammed to another monitor. (only repair sensors can be programmed only once).
Anti-band (or an antivenous) ring on the nipple (the principle of simple-ring of grooves and lock, and on the counter-response).
To summarize, I can say that the pressure and temperature control system in the TPMMS CRX-1002 was pleased with the simplicity of the installation (it is easy to move from rubber to rubber, from car to car), accuracy of reading, reliability, power of the battery monitor (the nest of the cigarette lighter).
In short, I am satisfied with the purchase of this system. The first time was watching the monitor all the time, it was amusing to watch the temperature and pressure increase during driving (the child is still watching), now rarely looking at it, hanging quietly and not disturbing it.
The price of the question is: 7,000 rubles.
