Flow Sensors Tout High Resolution, Accuracy Over Complete Measuring Range

Thu, 11/17/2011 - 7:09am


thermal mass flow sensorsSensortechnics offers sensitive thermal mass flow sensors for air and gases with measuring ranges up to 500 l/min. For medical ventilators, the company offers custom solutions with two sensing elements featuring desirable resolution and accuracy over the complete measuring range. One sensor chip is located in the middle of the main stream for the measurement of very small flows around the zero flow point. A second chip is arranged in a bypass configuration and measures higher flows up to full scale. The flow sensors use a microcontroller for digital signal processing and can continuously switch between the two sensing elements. Sensortechnics’ mass flow sensors are asserted to achieve very fast response times below 10 ms and offer a linear analog output signal and a digital I2C or SPI bus interface at the same time.
