The two versions complement the comprehensive product range of Sensirion’s digital differential pressure sensors in the SDP600 series. Along with the other products of this series, they offer a digital I2C output and are fully calibrated and tem-perature compensated. Thanks to the principle of calorimetric flow measurement, the CMOSens® differential pressure sen-sors achieve outstanding sensitivity and accuracy, especially around the zero point. Furthermore, the sensors exhibit very high long-term stability and freedom from zero-point drif
Digital differential pressure sensors with very low measurement ranges
Sensirion has recently launched two new versions of its differential pressure sensors with-in the SDP600 series. The new sensors SDP6x0-125Pa and SDP6x0-25Pa feature par-ticularly low measurement ranges of -125 to +125 Pa and -25 to +25 Pa, respectively. Due to their better resolution, the new products have improved zero point accuracy of 0.1 Pa. In addition, zero point repeatability reaches a remarkable 0.05 Pa for the 125Pa ver-sion and 0.03 Pa for the 25Pa version. The new differential pressure sensors are excel-lent solutions for many applications in medical and HVAC markets where high accuracy measurements of particularly low differential pressure are required.
