MEMS Pressure Sensor Transducer for Shield Tunneling Machine

Sturdy structure, good long-term stability
No cavity flat film, anti-clogging design
Vibration resistance, impact resistance, and abrasion resistance

Tunnel Shield Machine
Brick-making machinery
Petroleum exploration and water conservancy river dam

The PT219 series MEMS pressure sensor transducer adopts a high-precision pressure core and precision compensation technology for wide-range temperature compensation. The pressure-sensitive diaphragm adopts a solid diaphragm with a special treatment. The superb mechanical transmission structure design ensures that the hard sand in the measured medium will not damage the isolation flat diaphragm, compact structure, corrosion resistance, vibration resistance, and impact resistance of hard sand particles. Mainly used in various engineering equipment, tunnel shield machinery, brick-making machinery, liquid pressure, oil exploration, and mud measurement of water conservancy river dams.
