Caisson Method for Measuring Sensor
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
