多年来，我们已经数次提出涂层测厚仪的机械结构设计落后，马达、变频器、编

Over the years, we have repeatedly proposed that the mechanical structure design of the coating thickness gauge is backward, and the motors, inverters, encoders, clutches, couplings, etc. are too complicated and difficult to maintain. In 2019, Thermo also stated that it has carried out design improvement work. It has been more than 2 years now, and Thermo is requested to inform us of the design improvement and the follow-up schedule.

Over the years, we have proposed several times that the mechanical structure design of coating thickness gauge is backward, the motor, frequency converter, encoder, clutch and coupling are too complex, and the maintenance is difficult. In 2019, thermo also stated that it has carried out design improvement work. Now it has been more than two years. Please inform thermo of the design improvement and the subsequent schedule<br>
