High-Grade Metal Flow Controllers
MODEL 5100 SERIES
Model 5100 Series Mass Flow Controller/Meter features weldless structure, metal seals, the accuracy of ≤±1%, the response of ≤±1 second and other basic performance conditions required for semiconductor process control, and additionally, has achieved a significant price reduction.
– High accuracy and high response are achieved by the flow sensors with temperature- following current difference detection. – A normally-closed solenoid valve is employed. – A low leak rate is achieved by the weldless structure and metal seal. – The dead volume is reduced thanks to the diaphragm seat valve.- – The face-to-face and body dimensions and the wiring tie-in points are designed to facilitate the replacement of devices made by other companies.
