Abstract
PURPOSE: To enable the resolution not lowered even with the usage for a long time at high temperature, by constituting the damper of electroacoustic conversion probe with the joint of ferrite system stainless steel and austenite system stainless steel.
CONSTITUTION: At the bottom of the case 1 made of stainless steel, the piezoelectric element 2 is contained via the contact media 3a and the insulation cylinders 4a and 4b are contained. The damper 5a incorporates the austenite system stainless steel 5b and the ferrite system stainless steel 5c with welding in advance before locating it in the case 1. One end of the core wire 7 of the sheath wire 6 is connected to the damper 5a, another end is connected to the power supply through the center hole of the cap 8, and the external tube 9 of the sheath wire 6 is connected to another end of the power supply. The probe of this constitution can withstand the temperature change up to 1600°C and can give sufficient performance as the damper.
