GP High Pressure Transducers
Standard Equipment by HPI, Austria
The GP Series’ front sealing transducers all have the identical exterior dimensions, an M10x1mm thread, and are compatible with currently used NATO measurement bores. For tests with a piezoelectric transducer, charge amplifiers and common wires can be utilized.
The most difficult task in creating a new generation of transducers was to identify a better piezoelectric material than quartz.
The industrial method for producing gallium phosphate ensures the piezo material’s consistent quality and is crucial for requirements like:
- High accuracy
- High reliability
- High sensitivity
- Wide measuring range
- Small Dimension
The method of industrial growth ensures a consistent level of material quality.
Features
- Better accuracy by high sensitivity
- Excellent temperature behavior by use of GaPO4
- 800 MPa despite small dimensions
- “GP6” NATO APPROVED / NSN6685-41-000-7580
