Setra’s Model 227 transducer is designed for high density, surface mount gas sticks and panels, required for today’s 300 mm tools. The Mode 227’s 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. 316L VIM/VAR stainless steel wetted materials 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 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. Versatile configuration options Available with 5 VDC, 10 VDC, or 4 to 20mA output, the Model 227 offers Ultra-High Purity Pressure Transducer +_0.25% Full Scale or 1.0% of Reading accuracy. The Model 227 comes a multiconductor cable, 4-pin bayonet connector, and 9 or 15 pin D-sub • Variable capacitance technology 1-1/8” rotatable display, this package provides the ultimate in pressure • High resolution & longterm stability measurement and local readout. with a industry standard 1-1/8” C-Seal surface mount base with choice of connector for electrical termination. When coupled with the Model 328 • Small cavity, efficient purge cycles • Semi F19/F20 compliant 316L VIM/VAR wetted materials Side access to the zero and span adjustments beneath the rotating • EMI/RFI immunity prevents false shutdown protective cover, and choice of absolute, gauge or compound pressure • Optimal non-incendive approval for use in potentially hazardous ranges complete this unique design. locations available for 4-20mA output units • CE & RoHS compliant Principle of operation Setra’s patented variable capacitance sensor features a 316L stainless steel diaphragm and an insulated electrode plate.
