MCE/MCV–Series: Vacuum Gas Mass Flow Controllers

Use MCE/MCV-Series Vacuum Gas Mass Flow Controllers to update your vacuum deposition fixtures. The MCE–Series includes welded 1/4″ VCR fittings and matches end to end with SEMI standard MFCs, and the MCV–Series is additionally equipped with a pneumatic shut-off valve for hard vacuum applications.

Drop-in compatibility. Form factor includes welded 1/4″ VCR fittings and matches end to end with SEMI standard MFCs.
Versatile & accurate. Real-time control with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.
