Model 204 0 pages

Setra’s Model 204 pressure transducers
are intended for accurate pressure
measurements of gas or liquid
media compatible with 17-4 PH stainless steel.
The high level output signal and excellent
stability, combined with fast dynamic
response, make this unit ideal for industrial,
laboratory and aerospace applications.
The exceptional accuracy is achieved by
combining Setra’s unique electronic circuitry
with its patented variable capacitance sensor.
This unit is compensated for both zero and
sensitivity shifts due to environmental

temperature variations. The Model 204, with a
high-level 0-5 VDC output, and the Model
C204, with a high-level 4-20 mA output,
require no additional signal conditioning. The
sensor features a one-piece 17-4 PH stainless
steel pressure sensor and an insulated electrode,
which form a variable capacitor. As the
pressure increases, the capacitance decreases.
This change in capacitance is detected and
converted to a linear DC electric signal. On
absolute pressure units, the reference side of
the diaphragm is sealed by electron beam
welding under high vacuum.
