In combined gas-and-air systems such as boilers, the air/fuel ratio can be accurately and quickly regulated using a mass flow sensor. This enables the boiler to be dynamically adjusted, meaning that it can run more efficiently and adapt to changing conditions more quickly.
The rising demand for energy-efficient applications in combination with the proven and improved differential pressure sensors produced by Sensirion has led to great success in the VAV (variable air volume) market. Able to draw on extensive expertise in reliable and precise air flow measurement, the sensor producer is expanding its product range with the SDP821 and SPD831. These Sensirion products provide the ideal solution for applications with high requirements for type B and type C fail-safe operation.
The small form factor enables the SDP821 and SPD831 to be integrated into a host of different applications. They are intended for use in high volume OEM applications. The differential pressure sensors excel in particular due to their rapid response time and fail-safe operation. They offer exceptional repeatability and a sampling rate of up to 2 kHz. The fully calibrated, temperature-compensated sensors are available in a variety of models.
The SDP800 series is based on Sensirion’s own patented CMOSens® Technology, which measures differential pressure using a thermal measuring principle. Sensirion differential pressure sensors have no zero-point drift and outperform conventional sensors with piezoresistive membranes in terms of sensitivity at low differential pressure levels, offset drift and hysteresis. The sensors are not sensitive to shocks or fluctuations in temperature.
