Differential Pressure Sensors SDP1108
Not Recommended for New Designs (NRND)
We recommend the SDP800 or SDP3x differential pressure sensor as successor of the SDP1108.
The SDP800 series and the SDP3x offer a better cost/performance ratio and are based on the new chip generation, which includes an extended feature set.
The SDP1108 is available to existing customers for support of their running production.
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 offers high resolution, sensitivity and accuracy, even at very low differential pressures. Furthermore, it exhibits high stability, is free of zero point drift and features square-root output characteristics for a wider dynamic measurement range. The faster response time - compared to the SDP1000 series - makes the differential pressure sensor an ideal solution for respiratory devices and time-critical process automation applications.
Features
- Analog voltage output: 0 to 4 Vdc
- Highest dynamic range thanks to root-square output characteristics
- Fast response time: 8 MS
- Outstanding accuracy and sensitivity thanks to principle of dynamic measurement
- No offset, zero drift, hysteresis free
- Fully calibrated and temperature compensated
Applications
Characteristics of the SDP1108
| Calibrated range: | Accuracy*: | Characteristic: |
|---|---|---|
| 0 to 500 Pa +2" H2O | 0.2% FS / 1% m.v. | root square |
*FS = full-scale or span; m.v. = maesured value; the bigger value is valid
