KG-A Crack Displacement Transducer
±2 mm/±5 mm 
This displacement transducer is set across a crack on the surface of concrete or across a joint between two concrete blocks to measure the displacement of surface gaps. Its waterproof structure allows this transducer to make stable measurement outdoors over a long period of time. Mounts using an achor bolt (KGF-11) or mounting brackets (KGF-31).
Temperature-integrated model with built-in thermocouple also available.
Protection ratings : IP 65 equivalent
