Multi-channel Flow Rate Sensor ControllersThe Flow rate sensor detects workpieces lifted by vacuum that could not be detected by the pressure sensor. Output Mode A single controller detects four points at the same time ■ Window comparator mode 1 Mode for freely setting LI and L2. Note, however, that switch output does not go ON while flow rate is increasing. Discharge to Vacuum atmospheric valve ON pressure Workpiece Vacuum lifted by break Connectable to a personal computer • Use a PC to perform flow rate setting, capture of flow rate value, and reference flow rate setting. I Window comparator mode 2 and 3 Modes for automatically setting LI, using AL setting and reference flow rate capture. (Li = Reference flow rate — AL) Discharge to Vacuum Workpiece Vacuum atmcspheric vaf/eON lifted by break pressure * vacuum Three types of sensor heads, depending on flow rate range • Three types are available, including -500—500 m2/min (ANR), [-30.5'—30.5 in.3/min.] -3~3 0/min (ANR), [-0.11—0.11 ft.3/min.] and 0— 10 0/min (ANR), [0—0.35 ft?Anin.]. Switch output . Reference tow rate capture Not affected by piping resistance ►Window comparator mode 2 When LI has been set, this mode maintains it unchanged until reference flow rate capture is performed again. Mode for freely setting LI and L2. • Since the flow rate sensor head is not affected by piping resistance, there is no restriction on mounting position. Nozzle hole diameter 0.1 mm [0.004 in.] JSi Based on Koganei test standard. •Window comparator mode 3 • Each time the LI setting is deleted when switch output goes OFF, this mode performs reference flow rate capture and sets Li. Effective for situations where flow rate fluctuation is severe. When using window comparator mode 3, use RS232C to perform reference flow rate capture from outside.
