Omega Engineering PX429-050GV Pressure Transducer

Overview

The Omega Engineering PX429-050GV is a high accuracy piezoresistive pressure transducer with a proven track record in high performance commercial and aerospace applications for over 25 years. It uses molecularly embedded strain gauges within a highly stable silicone wafer, sealed in a chamber protected by glass-to-metal seals and a stainless steel diaphragm. A sealed chamber with silicone oil transfers pressure from the diaphragm to the strain gauge bridge, providing exceptional accuracy, stability, and minimal thermal effects.

Key Features

• Piezoresistive strain gauge construction for high accuracy and stability
• Silicone oil pressure transmission for reliable isolation

• 100% pressure and temperature cycle testing on all units
• 5-point NIST traceable calibration certificate included
• Built-in reverse polarity, EMC, and power supply fluctuation protection
• Excellent long-term stability and repeatability

Applications

• Commercial aviation and aerospace pressure measurement
• High performance industrial applications
• Critical process control and monitoring
• High reliability pressure sensing systems
