The complete AMS unit is factory assembled and tested to provide accurate setpoint monitoring at all times. The unit comes standard with a honeycomb airflow straightener, pressure sensing station and a high performance glass-on-silicone pressure transducer. The sensing blades are extruded aluminum with a clear anodize finish. The pressure transducer output signal is field selectable and can be routed to a building automation system for continuous monitoring of the flow. With a simple jumper setting you may choose either a 0 to 5 Vdc or 0 to 10 Vdc output signal. The output signal is proportional to CFM.
