Sensirion (Westlake Village, CA) has introduced the SDP2108-R, a sensor solution for measuring air flows in medical ventilation applications. The sensor features an extended measuring range of 0 to 3500 Pa. The sensor is fully calibrated and temperature compensated; it features a response time of 8 ms and provides an analog output signal with a range of 0–4 V. The root square output enables accurate measurements at small differential pressure levels, while allowing the sensor to cover a wide dynamic measuring range. The sensor utilizes the principle of thermal flow measurement to achieve sensitivity and accuracy even with extremely small differential pressures. Unlike membrane-type differential pressure sensors, the SDP2108-R exhibits very high stability and freedom from zero point drift.
