The on-line detector in the invention is used for continuous on-line detection of propofol anesthetic in human blood during operation, and guides doctors to administer clinically.

The invention discloses a method for detecting the thickness of a steel tape on line. Firstly, a plurality of pairs of transmission roller groups are utilized to change the transmission direction of the steel tape, wherein two pairs of transmission roller groups are adjacent to each other, one pair is arranged right above the other pair of transmission roller group, and the steel tape is enabled to be transmitted vertically upwards for a distance. Two pressing blocks are arranged on two sides of the steel tape transmitted vertically upwards, the two pressing blocks are driven by one driving device. The driving device drives the two pressing blocks to clamp each other and be separated from each other. The integral body formed by the two pressing blocks and the driving device are fixed on a moving plate. The moving plate is capable of moving freely along the vertical direction. When the two pressing blocks clamp the steel tape tightly, the steel tape drives the moving plate to move vertically upwards. A thickness measuring device measures the thickness of the part, clamped by the two pressing blocks, of the steel tape. According to the invention, the thickness online measurement of the steel tape in the production process is realized, data obtaining is convenient and the measuring work of coiled steel tapes are greatly facilitated.
