Pressure Ranges
The top external zero and span adjustments complete
this unique design for all UHP down-mount
applications. Setra's patented variable capacitance
sensor features a 316L stainless steel diaphragm and an
insulated electrode plate. A variable capacitor is formed
between the sensor body and the electrode plate. An
increase in pressure causes a slight rounding of the
diaphragm, which decreases the capacitance. The capacitance
change is detected and converted to a
highly accurate linear DC electric signal by Setra's
unique custom integrated circuit, utilizing a patented
charge balance principle.
Setra’s entire Ultra-High Purity series is based on Setra's
proven capacitive sensing technology with highly
accurate and stable voltage or current output signals
that are virtually EMI/RFI immune.
Setra maintains a 700 square-foot, vertical laminar flow,
Class 100 clean room, where all UHP producst are carefully
cleaned, tested, inspected, double bagged and back-filled
with high-purity nitrogen and sealed for shipping.

Setra's Model 217 Transducer is designed
for modular "Block" gas sticks
and panels. The 217 is ideal for pressure
measurement applications that require
exceptional insensitivity to environmental
extremes, such as temperature transients
resulting from the flow of cold gas.
The Model 217, available with a C-Seal or W-seal
down-mount pressure port, has a small swept
sensor chamber for easy purgeability. All wetted
parts are 316L VIM/VAR stainless steel passivated
to 5 Ra (7 Ra. max.) finish, which eliminates surface
irregularities and provides the proper
surface chemistry for corrosion resistance, assuring
contaminant-free gas distribution. Every
sensor is mass spectrometer helium leak tested to
1 x 10-9 atm.cc/sec.
The 217 is offered with a 5 VDC, 10 VDC or 4-20 mA
output. A variety of standard electrical terminations
are offered.
