The Setra 224 Flow-Through Specialty Gas Pressure Transducers are designed for the most demanding specialty gas monitoring and control applications, where construction integrity, purity and performance cannot be sacrificed.

The 224 has a small, streamlined sensor chamber for easy purgeability. The sensor is designed to provide superior mechanical and thermal stability, especially in transient temperature conditions resulting from flowing gases. Isolation of the sensing element from the pressure fi tting virtually eliminates any torque effect.

This superior mechanical and thermal stability is achieved through Setra's patented variable capacitance sensor. Its fundamentally simple design features VAR 316L SS wetted parts, passivated to 5 Ra (7 Ra. max.) fi nish for system continuity, and an insulated electrode plate fastened to the center of the sensor diaphragm, which forms a variable capacitor. As pressure increases or decreases, the capacitance changes. This change in capacitance is detected and converted to a linear analog signal by Setra's unique electronic circuit.

Various tube diameters are available with optional face seal fi ttings. Sturdy construction allows for trouble-free installation and high tolerance of system torsion and welding effects, providing confi dent installations.

Model 224 transducers are able to endure bakeout to 185°F (85°C), without affecting calibration. Every sensor is mass spectrometer helium leak tested to 1 x 10-9 ATM.CC/sec.

This ultra-high purity series is based on Setra's proven capacitive sensing technology and the highly accurate and stable voltage or current output signals are virtually EMI/RFI immune.

Applications include:

  • High purity gas delivery systems
  • Semiconductor process tools
  • Pharmaceutical & biotech process
  • Gas cabinets
