1-3 Description
Brooks Instrument’s Model SLA7840 is a 1-1/8" wide profile metal sealed
instrument that controls pressure while measuring flow rate. The Model
SLA7840 receives a remote pressure transducer signal, and using
adjustable integral PID control electronics and a control valve, maintains a
desired set pressure. In addition to the pressure function, the Model
SLA7840 provides a 0-5 V signal that is linear with mass flow rate. The
Model SLA7840 can also be configured as a mass flow controller for
calibration or test purposes.
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 SLA7840 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 SLA7840 to serve as a direct replacement for existing analog
products bringing with them greatly improved accuracy and reliability.
