1-3 Description
The Brooks
®
Model SLA5840 Pressure Controller/Flowmeter is designed to
control pressure while also measuring flow rate. The Model SLA5840
receives a remote pressure transducer signal, and using adjustable
integral PID control electronics and control valve, will maintain a desired
set pressure. The Model SLA5840 can also be configured as a mass flow
controller for calibration or test purposes.
Brooks now offers control interface with DeviceNet and Profibus, two high-
speed digital communication networks. Other network protocols are in
development. Talk to your Brooks representative about your specific needs.
The MFC's microprocessor uses a multi-point calibration curve, to deal
with residual sensor non-linearity, yielding a highly accurate process signal.
The microprocessor then executes Brooks’ proprietary Adaptive Valve
Control algorithm to rapidly adjust the valve actuation to match setpoint.
Process data and commands may be wired using either traditional analog
connections or digital communications networks, the measurement and
control performance is the same!
The SLA5800 family of products takes advantage of modular design in
both mechanical and electrical construction. This modularity allows for
