Autoclave internal precise force measurement device

Relating to the technical field of driving force measurement, the invention in particular discloses an autoclave internal precise force measurement device. The device comprises a drive rod, force sensors, signal cables and a cable sealing component. Specifically, the drive rod passes through an autoclave shell from the bottom up, and a dynamic seal installed between the autoclave shell and the drive rod is utilized for sealing; the force sensors are arranged on the inner wall surface of the drive rod, and the signal cables connected to the force sensors pass through the cable sealing componentso as to lead signals of the force sensors out to a signal acquisition system. According to the force measurement device, the force sensors are arranged inside the autoclave, the interference of dynamic seal frictional force is eliminated from the measured force signal, thus significantly improving the force measurement precision; at the same time, the force sensors installed inside the internalcavity of the drive rod do
