The A series
1.5%, 1%, 0.5%, FSO, BFSL: it pays to look closely and make a fair comparison.
In 2013 we launched the new generation of its MEMS pressure sensors, the A series. Based on a 2-chip concept (Sensor Die+ ASIC), the solution quickly proved itself on the market and is now widely used in many applications. At first glance, the Japanese sensors do not necessarily stand out from their rival products. But if you look more closely, you will notice that most competitors define accuracy according to the BFSL method and place the typical values in the foreground. Fujikura, in contrast, defines accuracy or the maximum error (Fig. 1) as the maximum deviation from the expected measured value over the entire pressure and temperature range – which is actually the most consistent and honest definition, just not the one with the best values at first glance.
