GP-2000 Pressure Sensor
Range from 0.35 MPa to 70 MPa
Isolated oil-filled sensing structure
316L stainless steel housing
Compact size φ12.6 mm
Temperature compensated
High overload resistance
The GP-2000 isolated oil-filled pressure sensor is designed for reliable pressure measurement in demanding industrial environments. The sensor integrates a MEMS silicon sensing element with an oil-filled isolation structure, allowing the measured pressure to be transmitted through a stainless-steel diaphragm to the sensing chip. This structure protects the sensing element from direct media contact while ensuring stable pressure transmission.
The compact sensor body with a diameter of 12.6 mm allows easy integration into pressure transmitters, hydraulic equipment, and embedded measurement systems. Integrated temperature compensation improves measurement stability across varying operating temperatures.
With its 316L stainless steel housing and robust mechanical design, the GP-2000 offers strong resistance to overload and mechanical stress. These characteristics make the sensor suitable for applications such as hydraulic systems, pumps, loading machinery, and industrial process control where stable pressure sensing is required under demanding operating conditions.
