The invention provides a marine high-static-pressure-resistant pressure difference measuring device, a ship and a measuring method. The device comprises a shell, a pressure difference sensor and a signal output part. The first end of the shell in the length direction is used for being connected with a hull shell, and the second end of the shell in the length direction extends into the hull shell.The shell is provided with a first pressure inlet hole, a second pressure inlet hole and a containing cavity communicating with the first pressure inlet hole and the second pressure inlet hole. The pressure difference sensor is arranged in the containing cavity, a first sensing end of the pressure difference sensor is communicated with the first pressure inlet hole, and a second sensing end of thepressure difference sensor is communicated with the second pressure inlet hole; and the signal output part is connected with the shell and is electrically connected with the pressure difference sensor. According to the marine high-static-pressure-resistant pressure difference measuring device, the ship and the measuring method, the pressure difference between the inside and the outside of a shipbody is measured by one pressure difference sensor according to the received media from the outside and the inside of the ship body, the static pressure on the two sides of each pressure difference sensor is offset, meanwhile, errors caused by inconsistent environments do not exist, and the measuring precision is high.

    本公开提供一种船用耐高静压的压差测量装置、船舶和测量方法,装置包括:壳体、压差传感器和信号输出件;壳体沿其长度方向的第一端用于与船体外壳连,壳体沿其长度方向的第二端延伸入船体外壳内;壳体设置有第一进压孔、第二进压孔以及分别连通第一进压孔和第二进压孔的容纳腔;压差传感器设置在容纳腔内,压差传感器的第一传感端与第一进压孔连通,压差传感器的第二传感端与第二进压孔连通;信号输出件与壳体连,与压差传感器电连接。本公开一种船用耐高静压的压差测量装置、船舶和测量方法,用一个压差传感器根据接收的来自船体外内介质测量船体内外压差,单个压差传感器两侧的静态压力互抵消,同时不存在环境不一致引入的误差,测量精度较高。
