Setra’s Model 239 series of pressure
transducers are specifically designed for
very low pressure applications that
require high accuracy.
Setra’s variable capacitance sensor is designed
to be simple and reliable. A stainless steel
diaphragm and an insulated electrode form a
variable capacitor. As pressure increases or
decreases, the capacitance changes. This
change in capacitance is detected and
converted to a linear D.C. electric signal by Setra’s unique electronic circuit. The Model
239 provides a high level voltage output. The
C239 provides a 4-20 mA current output. High
positive overpressure protection is achieved
by the sensor electrode acting as a stop for the
diaphragm. The high level output signals,
excellent long term stability and fast dynamic
response make these transducers ideal for a
wide range of industrial, laboratory and
aerospace applications.
