Model 227 Ultra High Purity Pressure Transducer
Brand: Setra Systems, IncSetra’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 1-1/8" 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 purgeability.
All wetted parts are 316L VIM/VAR stainless steel passivated to 5 Ra (7 Ra. maximum) finish, which eliminates surface irregularities and provides the proper surface chemistry for corrosion resistance, assuring contaminant-free gas distribution.
FeaturesSemi F19/F20 compliant 316L VIM/VAR wetted materials Superior stability avoids downtime EMI/RFI immunity prevents false shutdown Optimal non-incendive approval for use in potentially hazardous locations available for 4-20 mA output units Meets CE conformance standards RoHS compliant.
