Abstract:
In this work, a highly sensitive pressure measurement device based on multimode fiber filled with
ultraviolet adhesive is presented. The experimental results show that the device has a high gas pressure
sensitivity of -40.94nm/MPa, a large temperature sensitivity of 213 pm/°C within the range from 55 to
85°C, and a relatively temperature cross-sensitivity is 5.2kPa/°C. The fiber device is miniature, robust and
low cost, in a reflection mode of operation, and has high potential in monitoring environment of high
pressure.
