Proven Application Environments
- Semiconductor CVD / PECVD / ALD process chambers
- Etch tool gas panels (N₂ purge and carrier gas lines)
- Diffusion furnace nitrogen ambient control
- Industrial gas blending and mixing systems
- R&D laboratory flow calibration benches
- Photovoltaic (PV) thin-film deposition equipment
Engineering Advantages
- Drop-in compatibility: Direct replacement for existing CELERITY DSVAF100-series installations — no re-calibration of the gas panel required when replacing like-for-like.
- Proven thermal sensing: DSVAF platform uses a bypass-type thermal mass flow sensor for long-term drift stability in continuous-duty applications.
- Normally-closed valve (ATN): Fail-safe design ensures gas flow stops on power loss, critical for safety-sensitive process environments.
- Wide dynamic range: 32–900 sccm range covers both low-flow purge and high-flow process steps within a single unit.
- Low dead volume: Compact internal flow path minimizes gas residence time, improving process response.
System Architecture & Signal Flow
The DSVAF100 integrates a thermal bypass mass flow sensor, a proportional control valve, and an onboard PID controller in a single body. Signal flow is as follows:
- Setpoint command received via 0–5 VDC analog input (pin 7 on D-sub connector).
- Thermal sensor measures actual mass flow; signal conditioned by onboard electronics.
- PID loop drives the ATN valve to minimize error between setpoint and actual flow.
- Flow output signal (0–5 VDC) available on pin 9 for real-time monitoring by host controller or MFC readout box.
- Valve override (open/close) available via dedicated pins for purge and emergency shutoff sequences.

Technical FAQ
Q: Is this unit calibrated for N₂ or can it be re-ranged for other gases?
A: This unit is factory-calibrated for IN2 (Nitrogen). Re-ranging for other gases requires recalibration using the appropriate gas conversion factor (GCF). Contact us for recalibration service options.
Q: What is the difference between DSVAF100 and DSVAF200 series?
A: The DSVAF100 is the standard analog interface variant; DSVAF200 typically refers to digital/DeviceNet-enabled configurations. Confirm your tool’s interface requirement before ordering.
Q: Can this MFC be used with corrosive gases?
A: This unit is configured for inert N₂ service. Wetted materials (316L SS, Viton) are not rated for highly corrosive halogen gases. Contact us if you require a corrosive-service variant.
Q: Do you provide a warranty?
A: Konmask.com offers a 30-day functional warranty on all listed units. Extended warranty and exchange programs available — inquire at support@konmask.com.
Q: What connector and cable do I need?
A: Standard CELERITY/Brooks 15-pin D-sub male connector. Mating cables and breakout boxes are available separately — ask our team for compatible accessories.
