NATM PRESSURE CELLS NATM PRESSURE CELLS

NATM RADIAL PRESSURE CELL 10-50 BAR

NATM Radial pressure cell designed to measure radial stresses in concrete and shotcrete tunnel linings. The cell consists of two steel plates welded together around the border and filled with de-aired oil. A flexible tube connects the cell to a certificate pressure transducer. A pre-stressing valve complete the cell. 

Measuring range: 0-1-5 MPa (10-50 bar) 

Resolution: 0.01 MPa 

Accuracy: better then 0.3 % of full scale 

Dimensions: 150x150x6 mm 

Operating temperature: -20°C to +80°C

Equipped with 10 meters of cable.
