USE THE FIBER-OPTIC LASER SENSOR WITH THE STRUCTURE OF THE NINE DENSITOMETER ARTICL

摘要

PURPOSE: A structure of a densitometer having a optical fiber mode sensor structure of using a laser light is provided to reduce manufacturing processes by directly inserting a sensor installation holder into a pipe. CONSTITUTION: A structure of a densitometer having a optical fiber mode sensor structure of using a laser light comprises a sensor installation holder(10) and a sensor unit(20). The sensor installation holder includes an insert pipe(11), a valve part(15) and a holder(17). The insert pipe is inserted to the inside of the pipe. A holder flange shift(16) is formed in the opposite side end combined to the top of the valve part. The sensor unit comprises the sensor pipe and a sensor flange shift. The sensor pipe comprises the radiation optical fiber and light accepting optical fiber. The sensor flange shift is formed on the top of the sensor pipe. The insert pipe of the sensor installation holder is inserted inside the pipe and the contact surface is welded. The sensor pipe of the sensor unit exposes through the inside of holder through the end of the insert pipe.
