TRAFAG’S THIN-FILM-ON-STEEL SENSORS SHOW, EVEN AFTER 20 MILLION CHARGE CYCLES, A DRIFT CLEARLY BELOW 0.05%.
Trafag’s thin-film-on-steel sensors, even after more than ten years, maintain their measurement values, in most cases, below 0.3% of their original state. One of the most challenging trials made by Trafag is that in which 20 million charge cycles are applied, with a minimum of 1.5x nominal pressure. Only a small quantity of our competence’s sensors resist this trial without damage to the sensor. On the contrary, Trafag’s thin-film-on-steel sensors show, even after 20 million charge cycles, a drift clearly below 0.05%; which means that they stay practically on their original state and without any damage. For sectors such as the railway, where both the rolling stock and the infrastructure must work reliably for a long period, it is vital that the installed sensors can also work correctly for many years under hard conditions. In these applications is where accuracy, reliability and precision are a must, all together with an excellent long-term stability on the measurement signal.
Additionally, our railway sensors comply to EN50155, EN45545, EN61373, EN50121 and EN60068.
Our H2 compatible sensors, manufactured using an austenitic steel, with a high content of Nickel and an N2 treatment, prevent embrittlement and permeability, being EC-79 certified.
