Digital Pressure Sensors achieve 0.1% offset stability.

Press Release Summary:




Employing flow-based technology that integrates flow channel with sensing elements, FPS Series offers pressure ranges of 0.1, 0.2, 0.4, 1, and 2 in. H2O. Low flow rates allow use of input filters and long pneumatic tubing without sacrificing calibrated accuracy. Sensors are available for use with 3 or 5 V supply voltage, and offer both analog and digital SPI output. Housed in miniature package with SMT and DIP lead configurations, FPS Series is immune to dust contamination and humidity.



Original Press Release:



Ultra Low Pressure Digital Sensor



The FPS Series employs an innovative flow-based technology that integrates a flow channel with sensing elements. Utilizing a proprietary chopper offset compensation technique; a superior offset stability is achieved better than 0.1%. This technology provides extreme miniaturization that reduces the gas flow rate providing a significant immunity to dust contamination and humidity. Lower flow rates also allow for the use of input filters and long pneumatic tubing without sacrificing calibrated accuracy. The FPS is based on sensitive thermal mass flow measuring principles that provide a high resolution signal. Both an analog and digital SPI output is available. The FPS is designed with a microcontroller for precision digital signal conditioning that provides high resolution. Devices are available for use with 5V or 3V supply voltage.



The FPS Series is intended for clean air and gas applications that require high accuracy, long term stability, and low pressure measurements in Medical, HVAC and Instrumentation applications. Pressure ranges include, 0.1, 0.2, 0.4, 1, and 2 inH2O.
