Setra's Model 227 transducer is designed for high density, modular block gas sticks and panels required for today's 300 mm tools. The Model 227s 1-1/8" 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 purgeabiIity. 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.
Available with 5 VDC, 10 VDC, or 4 to 20 mA output, the Model 227 offers ±0.25% Full Scale or ±1.0% of Reading accuracy. The Model 227 comes with a space-saving 1 -1/8"C-SeaI 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 327 1-1/81" rotatable display, this package provides the ultimate in pressure measurement and display.
Side access to the zero and span adjustments beneath the rotating protective cover, and choice of absolute, gauge or compound pressure ranges complete this unique design.
