GP-2211 Flush Diaphragm Pressure Sensor
Measuring range up to 35 MPa
Food-grade oil-filled isolation
316L stainless steel housing
Flat diaphragm overload protection
G1/4 thread with flush membrane
The GP-2211 Flush Diaphragm Pressure Sensor integrates a high-quality MEMS sensing element with food-grade oil filling and a stainless-steel isolation diaphragm. This structure effectively separates the process medium from the sensing die, ensuring high accuracy, stability, and long-term reliability.
Each sensor undergoes strict aging, screening, temperature compensation, and output calibration to guarantee consistent performance across the full operating range.
The pure flush diaphragm combined with rear-threaded G1/4 connection eliminates dead zones and prevents media residue, making installation and cleaning easy. This design is especially suitable for hygienic processes, viscous fluids, and applications in food, pharmaceutical, and sanitary industries.
