Setra 227 Ultra High Purity Pressure Trandurcer

The Setra 227 Pressure Transmitter, known as the Ultra High Purity Pressure Transducer, is specifically designed to meet the requirements of high-density modular “Block” gas bars and panels used in 300 mm tools. Its compact size of only 11/8″ provides valuable space-saving advantages. Built with a robust construction, this model ensures high precision, long-term stability, and reliable pressure measurement even in harsh environments. The Setra 227 features a small sensor chamber design that facilitates easy purging, making it an excellent choice for a wide range of applications. All wetted parts are made from VIM/VAR 316L stainless steel and surface passivated to 5 Ra (maximum 7 Ra) to prevent gas contamination.

With its low leakage rate, VCR connector, and a maximum pressure rating of 200PSI/250PSI/3000PSI (depending on the product variant), the Setra 227 delivers exceptional performance. It undergoes a stringent ammonia leakage test at a level of 1×10-9 ATM.CC/sec, ensuring high-quality standards. The transmitter is equipped with anti-electromagnetic interference/RF interference protection, guaranteeing reliable operation and preventing any accidental downtime. The 4-20mA output type is non-flammable and suitable for use in potentially hazardous areas, complying with CE and RoHS standards.

The Setra 227 Pressure Transmitter finds widespread application in 11/8″ “Block” gas bars and panels, high purity gas delivery systems, and semiconductor process tools, providing precise and dependable pressure measurement solutions for critical processes.
