Setra 225 series of the ultra-high purity pressure transducer is designed explicitly for ultra-high purity gas delivery systems in semiconductor processes and control applications requiring an ultra-clean operation, high throughput, and ultra-long-term stability.

The 225 Series features a rotatable housing construction that allows the user to easily adjust the 12-turn potentiometer for zero and span fine-tuning. The standard rotary male/internal end face seal pressure interface meets the requirements of the semiconductor industry. In addition, the series also uses a variety of other interface types. The series is available in 5 VDC, 10 VDC, or 4-20 mA output types and can be electrically connected using a 6-foot multi-core cable and bayonet, D-Sub, or M12x1 connectors.

The 225 Series pressure transmitters feature Setra’s patented variable capacitance technology with VIM/ VAR 316L stainless steel diaphragm and insulated electrode plates. The insulated electrode plate and the sensor locally form a variable capacitor. As the gas pressure increases, the diaphragm becomes slightly rounded, reducing the capacitance. The sensor will detect the change in capacitance and convert it to a high-precision linear DC signal. Setra’s unique custom integrated circuits are fabricated using a patented charge-balance principle that is virtually immune to EMI/RFI interference.

After the manufacturing and assembly, Setra Ultra High Purity Pressure Transmitter is also subject to deionized water rinsing, high purity hot nitrogen purging, drying, double layer packaging, nitrogen filling, sealing, and finally shipped.

Note: Setra’s quality standards are based on ANSI-Z540. The product is calibrated with NIST traceability, a US patent number.
