WIKA Model S-11 Flush pressure transmitter

Selection Notes

• Choose flush diaphragm when measuring viscous, particulate or sticky media
• Confirm process connection size (e.g., G1 B, G1/2 B) based on installation requirements
• Verify required pressure range from vacuum up to several thousand psi/bar
• Determine desired electrical connection and output (2-wire 4–20 mA or other options)

Why Choose the WIKA S-11 Flush Pressure Transmitter

• Flush Diaphragm Design: Prevents clogging and allows clean, dead-space-free pressure measurement — ideal for difficult media.
• Reliable Output: Standard 4–20 mA 2-wire output signal compatible with PLC/DCS and process automation.
• Stainless Steel Construction: Durable case and wetted parts withstand industrial environments and contamination.
• Wide Range Availability: Offered in many pressure ranges from vacuum to high-pressure options to suit diverse applications.
• Vibration and Shock Resistance: Robust sensor design resistant to spikes and mechanical stress.
• Low Maintenance: Easy to clean flush diaphragm reduces downtime and maintenance needs in tough process conditions.

FAQ
