Sidewall Air Velocity Sensing for Critical Containment and Industrial Applications

Sidewall Air Velocity Sensing for Critical Containment and Industrial Applications
Lab managers often choose to use sidewall sensors to maintain the face velocity of fume hoods and biosafety cabinets, instead of duct-mounted probe-style sensors, in applications where the exhaust flow is dirty or extremely hot.  The long term exposure of probe-style sensors to depositing particulates or corrosive chemicals may compromise sensor accuracy as well as reliability.  The sidewall or side flow sensor overcomes these issues by acting as a flow-through velocity device, drawing in clean, ambient air, rather than contaminated exhaust air, to measure airflow.  Sidewall sensors are typically mounted to the side of critical containment cabinets.
