Pressure Transducer. ST550 Datasheet
• Extremely small
• Stainless Steel construction
• High proof pressures for low ranges
• Ranges to 30K
• Hermetically sealed
The Series ST550 is an extremely small, accurate, reliable
pressure transducer for measuring dynamic and static pressures.
Available in absolute, sealed gage, or true gage zero pressure
reference, the unit is entirely welded of stainless steel. Major
feature of design is its small size. Other features include long
term stability, low sensitivity to shock and vibration, wide
temperature range, excellent response to transient pressures,
infinite resolution and built in over-pressure protection for ranges
• Alternative pressure ports
• Alternative electrical connectors
• Alternative materials of construction
• Expanded operating range
• Increased compensated temperature range
