Brooks Instrument recently announced several updates for the company's latest mass flow meters/controllers. The Model 4800 Series now has digital communications via RS-232 and a downport connection option. In addition, it is the first of Brooks' mass flow devices to be fully RoHS compliant.
RS-232 Digital Communication
This one-to-one communication protocol allows the customer to provide a setpoint and receive the process value, select one of nine gases for the calibration curve, access the valve override function, and access the re-zero function. The RS-232 protocol comes built-in to the product as part of its standard package.
Optional downport connections are now available on the Model 4800 Mass Flow Meter/Controller. In order to keep the advantage of the 4800 Series small footprint, Brooks utilized a proprietary standard downport option. This option allows top mounting for ease of maintenance and installation and also offers additional space savings over traditional mountings because there is no point-to-point tubing necessary.
The RoHS Directive places restrictions on the use of certain hazardous substances in electrical and electronic equipment. This directive bans new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, and certain other materials from being distributed in the EU. In Europe and Asia, customers continue to ask and require devices to be RoHS compliant. The 4800 Series is Brooks' first, fully RoHS compliant MFC.
Golden Gas Award Winner
Brooks is also proud to announce that its Model 4800 mass flow meter/controller recently won the Gold Award in the 2008 Golden Gas Awards competition in the Mass Flow Measurement and Control category from Gases & Instrumentation magazine, as judged by experts from academia and government. Judges were selected based on their expertise in the areas of technology that matched the award categories.
