FREQUENCY CHARACTERISTIC MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a frequency characteristic measuring device capable of easily performing frequency characteristic evaluation test of a vibration sensor for testing in any heating state. SOLUTION: The frequency characteristic measuring device includes a heating furtherance 1 and a waveguide bar 2 having a vibration sensor S1 for fixing at one end and a vibration sensor S2 for testing at the other end, wherein the vibration sensor S2 for testing is disposed in the heating furtherance 1 and the vibration sensor for fixing is opened to the outside of the heating furnace. The vibration sensor S2 for testing is held by a cap member 43 capable of screwing to the tip of the waveguide bar via a spring body 42. The material of the spring body 42 is ceramics.
