Sensirion's SDP2108-R is a sensor solution for measuring air flows in medical
ventilation applications. The new differential pressure sensor in the popular
SDPx108 family combines high speed and high accuracy with an extended measuring
range of 0 to 3500 Pa.
The SDP2108-R is based on the 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 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.
The SDP2108-R features extremely high precision and 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 high stability and freedom from zero
With an extended measuring range of 0 to 3500 Pa
and a fast response time of 8 ms, the SDP2108 has been developed specifically
for medical technology. In particular, it is an ideal solution for patient
ventilation applications. The SDP2108-R is also a solution for time-critical
applications in process automation and HVAC control systems.
