Caisson Method for Measuring Sensor

KKA-PB Caisson skin-friction meter 200kPa to 300kPa

The KKA-PB is a transducer to measure skin friction bearing force with the ground acting on thewall of concrete caisson. The transducer is installed so that the sensing area of the transducer faces thecaisson's wall and measures skin friction bearing force with the ground when settled and fixed.

 

Protection ratings : IP 67 equivalent

KKB-PB Caisson cutting-edge reaction meter 5MPa~15MPa

The KKB-PB is a transducer to measure subgrade reaction force (bearing force) acting on the caisson cutting edge. It is installed so that the sensing area of the transducer faces the bottom of the cutting edge and measures the reaction force when settled and fixed.
