Setra 227 Ultra High Purity Pressure Trandurcer

The Setra 227 Pressure Transmitter is a compact and robust model designed specifically for high-density modular “Block” gas bars and panels used in 300 mm tools. This model occupies only 11/8′′ of space, providing valuable space-saving benefits. Its rugged construction ensures high precision, long-term stability, and reliable pressure measurement in harsh environments. The Setra 227 features a small sensor chamber design that is easy to purge, making it an ideal choice for some applications. All wetted parts are made of VIM/VAR 316L stainless steel and surface passivated to 5 Ra (max. 7 Ra) to prevent pollution of gas delivery.

This pressure transmitter has a low leakage rate, VCR connector, and a maximum pressure rating of 200PSI/250PSI/3000PSI, depending on the product. It also features a 1×10-9 ATM.CC/sec level ammonia leakage test and anti-electromagnetic interference / RF interference protection to prevent accidental downtime. The 4-20mA output type is non-flammable and suitable for potentially hazardous areas, meeting CE and RoHS standards.

The Setra 227 Pressure Transmitter is commonly used in 11/8′′ “Block” gas bars and panels, high purity gas delivery systems, and semiconductor process tools.
