DESCRIPTION

ierra Instruments’ SmartTrak® 50 Series is a
digital gas mass flow controller designed to
meet the low-cost budgetary requirements
of OEM's while maintaining excellent quality and
performance. Inspired by the need for accurate and
reliable gas mass flow control at an OEM price,
the 50 Series delivers by building on the same
core sensor, LFE and valve technology found in our
award-winning SmartTrak 100 Series, all backed
by industry best off-the-shelf fast product delivery
and Sierra's style of personalized customer support.
Our 50 Series has a standard accuracy of +/- 1.0%
of full scale. The flexible and powerful direct-acting
control valve sets it apart from the competition by
minimizing leak-by, while offering a 300 ms response
time to setpoint changes at +/- 0.25% repeatability.

It is our philosophy that core sensor technology must
be of the highest quality and performance to make
an excellent MFC. In contrast to the many wetted
parts of CMOS and MEMS flow sensors, Sierra uses
its most advanced 316L stainless steel platinumwound capillary sensor technology ensuring the very
best mass flow control for nearly any clean gas. As
a result, the 50 Series shares the same advanced
sensor as the flagship SmartTrak 100 Series, while
incorporating a slightly varied valve and laminar
flow element design also inspired by the original
Smart-Trak. A more efficient manufacturing process,
a streamlined design, and our partnership with a
very strong supplier base combined to make the 50
Series a reality.
Experience our passion for flow with the 50 Series in
your next application.
