The AVS 1000 Series is an air velocity sensor designed to measure low velocity. The remote sensing head allows for measurement of airflow in small and confined locations. Designed as an embedded product, the AVS 1000 thermistor-based sensor has long-term stability and durability. The AVS 1000 Series is ideal for cleanrooms and VAV controls. Available linear outputs include 0-10V or 4-20 mA.

The AVS Series of airflow sensors is designed to directly measure airflow for embedded locations, such as cleanrooms, ductwork, and VAV systems. Directly obtaining airflow measurements eliminates the need for pressure pickup devices and conversion of pressure measurements to an airflow reading. The remote sensor allows the user to obtain measurements in small or tight locations, while the all solid-state technology gives the sensor stability and ruggedness. The processing electronics inside the AVS Series performs temperature compensation and linearization of output.

Choice of standard or customized calibrations

The Series 300 Airflow Switch is a line of solid-state highly reliable electronic switches, designed to monitor airflow in critical environments such as cleanrooms, semiconductor fabrication facilities, and operating rooms as well as in traditional electronic enclosures to warn of cooling degradation. These compact, easy-to-install units detect loss of airflow below a pre-programmed setpoint, and provide a fast and distinct warning of airflow deterioration.

Designed to replace traditional “sail” or “vane” switches, the Series 300 offers unparalleled resistance to shock and vibration. The Series 300 may be either uni-directional or bi-directional. The uni-directional model discriminates between forward and reversed airflow, indicating a fault if the airflow direction reverses. The bi-directional model accepts airflows from either of two opposing directions.

The output of the Series 300 can be used to drive computer logic or it can activate alarms, relays or other circuits. Normally-open and normally-closed versions are available.
