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.

Full Scale Ranges
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
NOTE: Setra adheres to strict quality standards including
ISO 9001 and ANSI-Z540-1. The calibration of this product is
NIST traceable.
