Differential Pressure Sensors SDP1108
Sensor for Air Flow Measurements in Medical Applications
The SDP1108 differential pressure sensor is a high-performance sensor solution, specially designed for air flow measurements in medical applications.
Based on the differential pressure sensors of the SDP1000 series, SDP1108 features the same high-value mechanical, electrical and physical characteristics. The SDP1108 sensor provides an analog output signal with a range of 0-4 V and is fully calibrated and temperature compensated. In addition, it has a high resolution. Thanks to the principle of thermal flow measurement the SDP1108 sensor series achieves outstanding sensitivity and accuracy even at extremly low differential pressures, exhibits very high stability and is freedom of zero point drift. Furthermore, the SDP1108 series offers square-root output characteristics for a wider dynamic measurement range. The faster response time - compared to the SDP1000 series - makes the differential pressure sensor a perfect solution for respiratory devices and time-critical process automation applications.
