Therefore, it is very interesting to once again ask about their real quality. The object of the next mini-examination was the contactless “de-pe-de-ze” for VAZ cars - three brands of three each.

[/ caption] The fact that all sensors will work did not cause much doubt. Another thing is how accurate and for how long. To find out more about this, we returned the purchased products to the Etalon test center for life tests. Their essence is to make each sensor turn back and forth a million times - at a frequency of 60 cycles per minute. Then, for a change, add this “one million torment” with two-hour heat resistance tests at a temperature of 130 ° C and only then speculate on the linearity of characteristics and other nuances.

[/ caption] Externally, the sensors do not differ much. True, a careful study of the packaging of the Kursk product immediately confused - what kind of working temperature range is it up to + 45 ° С? Whether it is not enough - 130 is supposed! By the way, it is precisely at temperature tests that the “smokers” will trip over, but it will be a bit later.

[/ caption] What are the sensors inside? Looking ahead, we say that when they were opened after the tests, it turned out that the same principle of operation (a ring magnet on an eccentric plus a microcircuit) each of the three factories embodied in their own way - this is clearly visible in the photo. Which solution is better? It is logical to assume that exactly what is inherent in the winning sensors. And this time Kaluga won!
