Sensor Venturi

The F-4417-10 Sensor Venturi is single units designed for 20 PSI pressure range. The Sensor Venturi allows a high velocity of air to pass through the center port drawing a vacuum through the two side output ports producing a definite off signal. For entirely free flow, the output level will be a vacuum, typically equal to 20% of the supply pressure. When sensor flow is obstructed completely, full supply pressure is diverted to the two side output ports. Two output ports are provided on each unit; cap the unused connection with a vinyl cap when required. The output state of each venturi shows on a black and white indicator.
