GP-2900 Differential Pressure Sensor
Wide range: 0 kPa to 3.5 MPa
Static pressure up to 20 MPa
Temperature compensated output
Stainless steel diaphragm isolation
High accuracy and long-term stability
Robust 316L stainless steel housing
The GP-2900 Differential Pressure Sensor is a robust industrial-grade piezoresistive sensor designed for accurate differential pressure measurement in gas and liquid applications under high static pressure conditions.
The sensor incorporates a MEMS piezoresistive sensing die hermetically encapsulated within a 316L stainless steel housing. High- and low-pressure ports are isolated from the sensing element by stainless steel diaphragms, ensuring reliable media compatibility, corrosion resistance, and long-term sealing integrity.
With a measurement range from 0 kPa up to 3.5 MPa and a maximum static pressure rating of 20 MPa, the GP-2900 is well suited for compact industrial differential pressure transmitters and instruments operating in demanding environments. Integrated temperature compensation delivers stable output across varying thermal conditions, while the classic mechanical structure ensures proven reliability, repeatability, and ease of system integration.
