The Brooks 4800 Series features a broad flow range, compact size, a variety of analog
and digital I/O options, a MEMS-based sensor that provides lightning fast response times,
and many other benefits for a variety of applications. The 4800 Series of mass flow
controllers and mass flow meters is fully RoHS compliant and is an excellent choice for
measurement and control of many common gases including air, N2, O2, Ar, He, H2, CO2,
CO, N2O, CH4, C3H6, and C3H8. The optional Local Operator Interface (LOI) provides a
convenient user interface to view, control, and configure the 4800 Series devices
eliminating the need for remote secondary electronics.
The 4800 Series MEMS-based sensor provides lightning fast response times.
The 4800 Series utilizes a Micro Electro Mechanical System (MEMS) based thermal sensor.
Similar to typical thermal sensors, it measures a change in temperature to determine
mass flow rate. The difference is that gas flows directly across the sensor, achieving
extremely fast response times.
Fast settling times and stable control come standard with the 4850 controller.
The Model 4850 uses a proprietary PID algorithm to optimize
the control valve response to ensure rapid settling times. The
4850 can be counted on to quickly match actual mass flow to
any changes in setpoint.
Good things come in small packages.
The MEMS sensor enables a dramatic reduction in size
compared to traditional thermal mass flow controllers and
thermal mass flow meters. In fact the compact size of the 4800
Series 1” x 3” x 4” (25mm x 76mm x 101mm) takes up less
than half the space of typical thermal mass flow controllers.
The 4800 Series is ideal for OEMs.
The broad flow range, fast response time, compact size and
the ability to store up to nine (9) gas calibrations make for a
perfect fit in any OEM system where gas flow needs to be
measured or controlled.
The Local Operator Interface (LOI) simplifies set-up and operation.
The LOI mounts securely on top of the 4800 Series device.
With status LEDs and a large backlit LCD it provides a
convenient user interface to view, control and configure the
Brooks 4800 Series thermal mass flow devices. This option also
allows the user to power the device with a simple power adapter
that plugs right in to the wall.
Fully RoHS compliant per EU Directive 2002/95.
Variety of input/output options.
The 4800 Series thermal mass flow controllers and thermal
mass flow meters come standard with voltage or current and
RS-232 I/O. These products are also available with RS-485 or
Profibus digital communications.
Software and support tools
The Brooks Smart DDE (Dynamic Data Exchange)
makes it easy to communicate with the 4800 Series RS-485
Digital devices. If you choose Profibus communications the GSD
file is available for download. If analog I/O is selected you can
download a free LabView VI to monitor and zero the device.
Easily integrated into modular gas delivery systems
The 4800 Series is available with downport connections making
it easy to integrate into modular gas delivery systems.
