Ultra-High Purity Pressure Transducer

Setra’s Model 227 transducer is designed for high density, modular
block gas sticks and panels, required for today’s 300 mm
tools. The Mode 227’s 1-18” footprint optimizes valuable space,
and its rugged design makes it ideal for pressure measurements
that require long-term stability, high accuracy and exceptional
insensitivity to environmental extremes.
Unlike many other designs with large dead-ended cavity volume,
the 227 has a small swept sensor chamber for easy purgeability.
All wetted parts are 316L VIMVAR 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.
Available with 5 VDC, 10 VDC, or 4 to 20mA output, the Model
227 offers +_0.25% Full Scale or 1.0% of Reading accuracy.
The Model 227 comes with a industry standard1-18” C-Seal or
W-Seal downmount interfacing base with choice of a multiconductor
cable, 4-pin bayonet connector, and 9 or 15 pin D-sub
connector for electrical termination. When coupled with the
Model 328 1-18” rotatable display, this package provides the
ultimate in pressure measurement and display.
