Differential Pressure Sensors SDP1000 Series
Not Recommended for New Designs (NRND)
The differential pressure sensor SDP1000 series is replaced by the differential pressure sensor SDP800 series. The SDP800 series is based on the new chip generation which offers better performance as well as new functionality. The SDP1000 series is only available to existing customers for support of their running production. The SDP2000 with extra high pressure range is still available.
Analog Sensor for Lowest Pressure Differences
The SDP1000 family of low differential pressure sensors provides precise differential pressure measurement with an analog 0 to 4 voltage output.
The fully calibrated and temperature compensated sensors feature high long-term stability and measure even miniscule pressure differences below 0.25 Pa (0.001 inch water). High performance and simple operation help minimize design effort. Several ranges from ±62 Pa to 0-3500 Pa (14 inch water) are available. The SDP1000 series is an ideal choice for demanding applications, for example medical and HVAC systems.
Features

- Fully calibrated and temperature compensated
- Not sensitive to the mounting orientation
Applications
- Medical
- Heating, Ventilating, Air Conditioning (HVAC)
- Gas Boilers, Gas Ovens, Pellet Stoves (Smart Energy)
- Industrial
- Automotive
Evaluation
Depending on your specific requirements you can choose between different versions. The individual characteristics are displayed below:
| Version: | Calibrated range: | Accuracy*: | Characteristic: |
|---|---|---|---|
| SDP1000-L025 | -62 to 62 Pa -/+ 0.25" H2O | 0.5% FS / 1.5% m.v. | linear |
| SDP1000-L05 | 0 to 125 Pa + 0.5" H2O | 0.2% FS / 1.5% m.v. | linear |
| SDP1000-L | 0 to 500 Pa + 2" H2O | 0.1% FS / 1.0% m.v. | linear |
* FS = full-scale or span, m.v. = measured value; the bigger value is valid
