Differential Pressure Sensors SDP1000 Series
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
- Accuracy of 0.1% full-scale near zero
- Amplified, analog voltage output: 0 to 4 Vdc
- No offset, zero drift, hysteresis free
- High dynamic range thanks to flow measurement principle
- 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
