The Setra 225 series is a dedicated ultra-high purity pressure transducer, designed specifically for gas delivery systems in semiconductor processes and control applications that prioritize cleanliness, stability, and high throughput.
With its rotatable housing construction, the 225 series offers convenient zero and span fine-tuning through a 12-turn potentiometer. The standard rotary male/internal end face seal pressure interface meets the stringent requirements of the semiconductor industry, while the series also provides various other interface options. It supports 5 VDC, 10 VDC, or 4-20 mA output types, and can be easily electrically connected using a 6-foot multi-core cable and bayonet, D-Sub, or M12x1 connectors.
The 225 series pressure transmitters utilize Setra’s patented variable capacitance technology, incorporating VIM/VAR 316L stainless steel diaphragms and insulated electrode plates. As gas pressure increases, the diaphragm undergoes a slight rounding, resulting in a decrease in capacitance. This change is detected by the sensor and converted into a high-precision linear DC signal. Setra’s custom integrated circuits, based on a patented charge-balance principle, provide exceptional resistance to EMI/RFI interference.
The manufacturing process of Setra’s Ultra High Purity Pressure Transmitter involves rigorous steps, including deionized water rinsing, high purity hot nitrogen purging, drying, double-layer packaging, nitrogen filling, sealing, and final shipment. These steps ensure the highest quality and purity standards are met.
