Embedded Sensing

Embedded Air Velocity Sensing Products

Cambridge AccuSense air flow sensors can be found embedded in mission critical telecommunications systems, medical and laboratory products, and in electronics equipment. 

Airflow sensors are offered with a number of sensor head options, including remote locations where the sensor itself can be up to 5 meters away. The sensor head's compact geometries allow unimpaired access in tight locations with minimal distortion of the measured airflow. Each sensor is calibrated in our NIST traceable wind tunnels to ensure stated accuracies. The sensors are designed to be fully interchangeable and to provide direct measurements of airflows in a variety of outputs. We also offer custom calibration ranges and custom sensor design. We have designed many sensor systems with control and relay boards for industries with unique airflow measurement requirements. As experts in the field of air flow management, we realize the importance of accurate and reliable airflow measurement. That’s why every air flow sensor with our name on it goes through stringent quality control, test, and calibration process.
