Function
DLTNA3-32099 is digital thermal mass flow controller manufactured by MKS Instruments. It continuously detects gas mass flow and dynamically adjusts valve opening to stabilize flow. All-metal construction minimizes particle generation and outgassing. Sensor contamination or valve seat wear will cause flow deviation and gas leakage. It is high precision gas flow regulation component for advanced semiconductor process.
Installation
Follow lockout/tagout safety procedure before installation. Isolate gas pipeline and release residual gas pressure. Mount DLTNA3-32099 on gas manifold following marked flow direction. Connect gas metal fittings and 24V DC power & signal cable. Complete leak test, zero calibration and closed-loop flow verification before operation.
Interface
Gas inlet and outlet metal compression fittings, multi-pin electrical connector for power, digital communication and analog signal, status LED indicators on housing of DLTNA3-32099.
Diagnostic
Flow reading drift: Sensor contamination or valve sticking. Cannot reach target flow: Supply gas pressure fluctuation or valve aging. Gas leakage: Fitting loose or metal seal damage. Communication failure: Wiring fault or control board abnormality.
