Abstract: In this paper, a system for supplying electric power and signal
transmission wirelessly for the hydrostatic loading device is put forward. The
electric power supplying and signal sending module of the system adopt
contactless transmission method, which is commonly called CPT (contactless
power transmission). Energy, with the form of a certain frequency of magnetic
field, gets through the austenitic stainless steel. Being used as the chamber
of the system, the austenitic stainless steel has the same relative magnetic
permeability as the vacuum. After travelling through the chamber wall, energy
is captured by the coil inside the chamber. Then it is converted into DC power
and sent to the loads inside the chamber [1]. Signal processing and sending
module converts the analog signals into digital ones and restore them. Data
consisting of signals is sent out from the chamber with the form of magnetic
wave. Devices outside the chamber receive the data and recover it.
