Differential Pressure Sensors SDP800 Series
SDP800 – Proven and Improved
Differential pressure sensors of the SDP800 series are the reliable solution for precise air flow measurement in most demanding but cost-sensitive HVAC applications, such as VAV controllers, burners, heat recovery systems and filter monitoring.
The SDP800 differential pressure sensors are based on the next generation of the CMOSens® sensor chip and consequently utilize the successful features of the SDP600 series. They are the result of more than 15 years of experience in measuring air flow in tens of millions of patients, car engines and HVAC systems. The sensors of the SDP800 series can easily be integrated due to their proven form factor. This next-generation sensor chip offers extended functionality, smart averaging functions and multiple measurement modes. Like all Sensirion differential pressure sensors, those from the SDP800 series are characterized by their outstanding accuracy and long-term stability, together with no zero-point drift.
Different Configurations Manifold or tube connection125 Pa or 500 PaDigital (I2C) or analog output
The digital version is highly versatile and features adaptable measurement speeds of up to 2 kHz, multiple measurement modes (triggered / continuous mode) and smart averaging functions. The version with analog ratiometric voltage output is configurable to either linear or square root by a separate pin. While the SDP80x is intended for a direct threaded connection to a pressure manifold via O-ring sealing, the SDP81x is designed for a tube connection.
Like all of Sensirion’s differential pressure sensors, the SDP800 series is based on Sensirion’s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using the flow-through principle. Thanks to this, Sensirion’s CMOSens® differential pressure sensors outperform traditional piezo-resistive membrane sensors in terms of sensitivity at low differential pressures, offset drift and hysteresis as well as position sensitivity, shock resistance and temperature variations.
