Differential Pressure Sensor With Extended Range for Medical Ventilation
The SDP2108-R is based on the proven SDP1108-R, which covers a smaller measuring range of 0 to 500 Pa, and it has similar mechanical, electrical, and physical characteristics. The SDP2108-R differential pressure sensor is fully calibrated and temperature compensated. It also features a very fast response time of 8.0 ms and provides an analog output signal with a range of 0-4 V. The root square output enables very accurate measurements at small differential pressure levels, while at the same time allowing the sensor to cover a wide dynamic measuring range.
Like all differential pressure sensors from Sensirion, the SDP2108-R features extremely high precision. The sensor utilizes the principle of thermal flow measurement to achieve outstanding 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.
