1-2 Description
Brooks Instrument’s Model SLA7810/SLA7820 are 1-1/8” wide profile metal
sealed instruments that accurately measure and control upstream or
downstream pressure. The heart of these devices is a solid-state pressure
transducer, which produces an electrical output proportional to pressure.
The electronics use this signal to operate a control valve and to provide an
output signal. The SLA7800 Series family of pressure measurement and
control products offers unparalleled flexibility and performance and is
designed for use in advanced gas handling systems. The result is the
most accurate, repeatable, and responsive controllers on the market today!
Superior Valve Technology
The co-planar valve offers unmatched performance. Due to its simplified
construction, the valve exhibits superior repeatability, stability, and
response time. Instruments are less sensitive to pressure variations in the
process because of the larger valve control range. The co-planar valve
also offers lower leak-by rates compared to other metal sealed controllers.
These advancements ensure a more stable process over time.
Highly Adaptable Configurations
The 1-1/8” body offers a compact, space saving footprint. The SLA7800
Series family of pressure controllers is easily retrofitable to existing gas
box designs that utilize the traditional 1-1/2” body platform. Likewise, the
all-digital electronics is adaptable and allows the SLA7800 Series to serve
as a direct replacement for existing analog products bringing with them
greatly improved accuracy and reliability.
Broad Array of Communication Options
Brooks offers the SLA7800 Series pressure controllers with a traditional 0-
5 volt analog option. Brooks also offers control interface with DeviceNet
TM ,
a high-speed (up to 500k baud) digital communication network. Brooks’
communication capabilities and device-profiles have been certified by the
ODVA (Open DeviceNet Vendor’s Association). Other network protocols
are in development. Talk to your Brooks representative about your specific
needs.
