Abstract
Disclosed is a device for recording a curing temperature history on precast concrete products, which is buried in a precast concrete product so as to record curing temperature and time histories during a steam curing procedure and to inform a user/inspector of recorded data, thereby controlling the quality of the steam curing concrete products. The device comprises: a socket formed in the shape of a hexahedron, including a collection chamber opened at the upper portion thereof, a hole formed through a lower portion of one side wall, and a magnet installed on another side wall and serving to operate a capsule when the capsule is inserted into the collection chamber, and to protect components of the capsule when the device is buried in a designated position of the precast concrete product to be cured; and a capsule formed in the shape of a hexahedron, accommodated in the collection chamber of the socket, and provided with a MCU (Micro Controller Unit) installed on a printed circuit board within the capsule and switched on/off by the magnet of the socket, senses a curing temperature of the precast concrete product by means of the control signal of the MCU when the device is buried in …
