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

The KKA-PC 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
