Taking measurements generally involves a tradeoff between measurement range and precision. Traditionally, pressure sensors are no exception to this rule: researchers and product developers must decide whether high-precision measurements are required at either the high- or low-pressure end of the range in any given pressure application. This presents significant challenges for accurately measuring pressures that vary over a large range. This is all about to change, thanks to a new flow-based differential pressure sensor capable of making measurements across a ±5,000 Pa range with sub-pascal precision at low pressure regions.
