Industrial Sensing

Product Selection Guide

Setra Systems, Inc. was founded in 1967 by brothers Dr.Y.T.

Li and Dr. S.Y. Lee, both professors of engineering at the

Massachusetts Institute of Technology and co-developers

of the variable capacitance transduction principle.

Building on this heritage of innovation, we continue to

design and deliver premium sensing devices for many

diverse applications and industries — innovating solutions

for HVAC & building automation, industrial OEM, test &

measurement, and critical environments.

Diaphragm

(conductive surface)

Setra is part of the Fortive group of companies, a diversied

industrial growth organization with 24,000 employees

worldwide. The Fortive Business System (FBS) is the

cornerstone of our culture and our ultimate competitive

advantage. It drives every aspect of our work, our strategy

and our performance. We use FBS to guide our decisions,

measure how well we execute and develop innovative ways

to do even better.

Variable capacitance

In a typical Setra conguration, a compact housing contains two closely
spaced, parallel, electrically isolated metallic surfaces, one of which is
a diaphragm capable of slight flexing under pressure. The diaphragm
is constructed of a low-hysteresis material such as 17-4 PH SS or a
proprietary compound of fused glass and ceramic (Setraceram).

Sensor body

Advantage of

capacitive

sensors

These rmly secured surfaces (or plates) are mounted so that a slight
mechanical flexing of the assembly, caused by a minute change in applied
pressure, alters the gap between them (creating, in effect, a variable
capacitor).The resulting change in capacitance is detected by a sensitive
linear comparator circuit (employing proprietary custom designed ASICs),
which amplies and outputs a proportional, high level signal.

Better for applications that are susceptible to over-pressurization

—

Very good hysteresis, linearity, stability, and repeatability, in

addition to static pressure measurement capability

—

Excellent accuracy in low pressure ranges – as low as 1 PSI.

Thin lm strain gauge

Thin lm pressure transducers are made by vapor deposition or sputtering
of insulation and strain gauge elements directly on a polished pressure
sensing diaphragm or beam. The desired strain gauge pattern is deposited
either by masking the non-conductive areas or by etching away unwanted
conductive material.

Through a sputtering process, a small circuit is created that contains on
it a Wheatstone-bridge resistance network. As pressure is applied to the
diaphragm and unbalances (or strains) the bridge, its electrical resistance
is changed and results in a voltage output.
