Zusammenfassung:	Disclosed is a smart device for anchoring/measuring a post-tensioning (PT) tendon used for a prestressed concrete (PSC) girder, capable of easily measuring the tension of a strand buried in a PSC girder. According to the present invention, the smart device for anchoring/measuring a PT tendon comprises: a wedge plate including a plurality of wedge mounting holes to mount and fix a wedge coupled to each of a plurality of strands thereinto; an anchor casting connected to the wedge plate at a front side to pass the plurality of strands; and a trumpet part connected to the anchor casting at a front side to pass the anchor casting and the plurality of strands, and connected to a duct at a rear side. The trumpet part comprises: a rear trumpet connected to the anchor casting; a front trumpet connected to the duct; and an EM sensor disposed between the rear and front trumpets to cover the plurality of strands. The rear and front trumpets are made of a nonmetallic material, and the wedge plate and the anchor casting may include a metallic material. PSC(Prestressed Concrete) 거더에 사용되는 PT(Post-Tensionning) 텐던 정착/계측 스마트 장치가 개시되며, PT(Post-Tensionning) 텐던 정착/계측 스마트 장치는 복수의 강연선 각각에 결합된 왯지가 안착 고정되는 복수의 왯지 안착 홀이 형성된 왯지 플레이트, 상기 복수의 강연선이 통과되도록 상기 왯지 플레이트와 전방으로 연결되어 앵커 캐스팅 및 상기 복수의 강연선이 통과되도록 상기 앵커 캐스팅과 전방으로 연결되고 후방으로 덕트와 연결되는 트럼펫부를 포함하되, 상기 트럼펫부는 상기 앵커 캐스팅과 연결되는 후방 트럼펫, 상기 덕트와 연결되는 전방 트럼펫, 및 상기 복수의 강연선을 둘러싸도록 상기 후방 트럼펫과 상기 전방 트럼펫 사이에 개재되는 EM센서를 포함하며, 상기 후방 트럼펫 및 상기 전방 트럼펫은 비금속 재질이고, 상기 왯지 플레이트, 상기 앵커 캐스팅은 금속 재질을 포함할 수 있다.
