J1 VIBRATING WIRE EMBEDMENT JOINTMETER

The Vibrating Wire Embedment Jointmeter is ideal for monitoring movement of joints in mass-concrete structures.

The jointmeter comprises two parts: a socket and a main body. The socket is a detachable end that is cast into the first lift of concrete. The main body is a protective outer case which houses a vibrating wire displacement transducer and screws into the socket. Once screwed into the socket, it is cast into the second lift of concrete.

The transducer has a vibrating wire sensing element which is anchored at one end and connected to a spring loaded push rod at the other end.
