详情描述


Suitable for measuring the soil pressure on the shield machine's liner and grouting pressure behind the wall


Even with surface wear under pressure, there is no effect on output and initial value.


Load Cell Type Soil Pressure Gauge, unaffected by bending


Particulate dust pressure for particle diameter φ10 or so


本质-safe explosion-proof construction


This sensor is unaffected by component bending in design and is a load cell-type soil pressure gauge, suitable for measuring wall soil pressure. Available in 12 and 18 models, it can be selected for use based on the installation direction.


Do not apply a load (pressure and weight) exceeding the rated capacity to the loaded surface for proper use. (Refer to the table.)
