Understanding the specifications
The available range of SPD series pressure sensors allows for a wide
range of applications. In order to get good results, it is very important to
fully understand the meaning of the various specifications and their
effects on accuracy, especially the ones that deal with temperature
coefficients. (Silicon resistors are very temperature dependent).
