Kofloc High-Grade Mass Flow Controller Model 3200 Series
High-grade Mass Flow Controller MODEL 3200 SERIES | Descriptions
Model 3200 Series Mass Flow Controller is an advanced model designed as a successor of the 3910 Series that enjoys wide use for diverse applications such as the manufacture of semiconductors, LCDs, combustion equipment, analytical devices, and biotechnology fields. Its high performance is equal to a new standard of KOFLOC.
– Equipped with a temperature follow-up type current difference detection flow sensor (patent applied for) to ensure high accuracy and high-speed response – Use of a normally closed valve to ensure safety – Reduced dead volume thanks to the diaphragm seat valve – Control of small quantities of flows available up to 1 SCCM full-scale (SR option) – Low differential pressure type control available for combustible gases (LP option)
Flow range (N2 equivalent, 20℃/1 atm): 1 SCCM–20 SLM (The conditions are freely selectable)
Sensor: Thermal mass flow sensor
Valve type: Proportional solenoid valve (closed when not energized)
Control range: 2–100% (F.S.)
Response : 1 sec. or less (0–100% within ±2% typical)
Accuracy: ±1% F.S. (Accuracy guaranteed at 15–35℃)
– Required power supply : +15 VDC (±5%) 100 mA, −15 VDC (±5%) 200 mA
– Joint (Main unit bore) : Standard: 1/4SWL Option: 1/8SWL 1/4VCR RC1/4, etc.
– Weight: Approx. 1000 g
Relating to the flow range (e.g., flow range, accuracy, and response) are expressed in N2 or air equivalent. The product will be built with the primary pressure of 300 kPa or less and the secondary side open to the atmosphere. For details on the pressure requirements, please contact us.
