Two versions of differential pressure sensors have been added to Sensiron's SDP600 series. The SDP6x0-125Pa and SDP6x0-25Pa feature low measurement ranges of -125 to +125Pa and -25 to +25Pa, respectively. The improvement in resolution results in zero point accuracy of 0.1Pa. Zero point repeatability reaches 0.05Pa for the 125Pa version and 0.03Pa for the 25Pa version. The differential pressure sensors are for applications in medical and HVAC markets where high accuracy measurements of particularly low differential pressure are required. As with the other sensors in the series, they have a digital I²C output and are fully calibrated and temperature compensated. The sensors are also claimed to exhibit very high long-term stability and freedom from zero-point drift.
