Description
The pore water pressure sensor makes use of the internal strain sensitivity of the FBG.
The head of the pore water pressure sensor is foreseen of a porous stone that allows water penetration. Dependent on the application, this stone can be flat (PWP-01) or cylindrical (PWP-02).
The sensor is temperature compensated using a second FBG.
Features
The pressure sensor can measure water pressure and temperature with a resolution of 0,1% Full Scale and an accuracy of 1% Full Scale. The pressure range can be chosen between 1 and 150 bar. The sensor can be used in harsh environment and is watertight according to IP68 BSEN60529.
Applications
The pressure sensor can be applied for flow control in all sorts of pipelines and liquid level measurement in reservoirs and others.
