SDP1000 Series - Differential Pressure Sensor

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 com- pensated sensors feature excellent long-term stability and measure even miniscule pressure differences below 0.25 Pa (0.001 inch water). Superior 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, e.g. 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

Depending on your specific requirements you can choose between different versions. The individual characteristics are displayed below:

Version:	Range:	Characteristic:	Accuracy*:
SDP1000-L025	-62 to 62 Pa	linear	0.5% FS / 1.5% m.v.
SDP1000-L05	0 to 125 Pa	linear	0.2% FS / 1.5% m.v.
SDP1000-L	0 to 500 Pa	linear	0.1% FS / 1.0% m.v.
SDP1000-R	0 to 500 Pa	root square	0.2% FS / 1.0% m.v.
SDP2000-L	0 to 3500 Pa	linear	0.1% FS / 1.0% m.v.

* FS = full-scale or span, m.v. = measured value; the bigger value is valid.
