Abstract
A device for diagnosing a moisture content of concrete includes an electromagnetic proximity sensor configured to cause an electromagnetic field to penetrate to a certain depth of concrete and to receive a detection signal that varies depending on a permittivity of the concrete within the covered region of the electromagnetic field; a current supply unit configured to supply current to the electromagnetic proximity sensor; and a diagnostic unit configured to analyze a moisture content of the concrete by using the detection signal.
Claims20
A device for diagnosing a moisture content of concrete, the device comprising:
- an electromagnetic proximity sensor configured to cause an electromagnetic field to penetrate to a certain depth of concrete and to receive a detection signal that varies depending on a permittivity of the concrete within the covered region of the electromagnetic field;
- a current supply unit configured to supply current to the electromagnetic proximity sensor;
- and
- a diagnostic unit configured to analyze a moisture content of the concrete by using the detection signal.
A system for diagnosing a moisture content of concrete, the system comprising:
- a concrete moisture content diagnosis device which includes an electromagnetic proximity sensor having a first side configured to face the concrete while making an electromagnetic field penetrate into the concrete, and which analyzes a moisture content of the concrete by using a detection signal that varies according to a permittivity of the concrete;
- and
- a moving device configured to connect to a second side of the concrete moisture content diagnosis device to move the concrete moisture content diagnosis device.
A method of diagnosing a moisture content of concrete, the method comprising:
- making, by an electromagnetic proximity sensor, an electromagnetic field penetrate to a certain depth of concrete and receiving a detection signal that varies depending on a permittivity of the concrete;
- deriving, a permittivity of the concrete by using the detection signal;
- and
- determining a moisture content of the concrete according to the derived permittivity.
