5850EM Series Metal Sealed Thermal Mass Flow Controller
Brand: Brooks Instrument5850EM Series metal sealed mass flow controllers measure and control high-pressure gas flows in ultra-clean environments with a proven stability built on the performance of the widely used 5850E & i Series MFCs.
Its metal sealed construction and electro-polished wetted surfaces ensure outstanding flow integrity and help improve overall process efficiency by eliminating the need for continuous monitoring and readjustment of gas pressures to provide a stable gas flow.
Features- Long-term zero stability of < 0.2% full scale per year
- < 3 seconds settling time to command changes with negligible overshoot/undershoot
- Wide flow range – from 3 sccm up to 30,000 slpm
- High pressure rating - up to 1,500 psi
- Optional enhanced process internal finish - 5µ inch Ra avg
- Removable flow sensor
- Insensitive to mounting attitude
- Mechanically and electrically compatible with other mass flow controllers
- TTL compatible "valve off" and purge function
Benefits
- All-metal flow path enhances gas purity and reduces leaks
- Proven long-term stability and accuracy across broad process and application range
- Excellent return on investment due to reliable performance
- Removable flow sensor eliminates need for continuous monitoring and readjustment of gas pressures
- Easily installed and serviced with analog only input/outputs
