Abstract
An alarm device for feedthrough assembly is proposed. The device comprises a body having a chamber, a sealing module configured on a first surface of the body for connecting to a feedthrough assembly, wherein a first surface has a hole across the chamber, and an alarm assembly configured in the chamber. In addition, if a shaft seal of the feedthrough assembly is failure, a pressure difference produced between the chamber and inner shaft seal forces the alarm assembly to move toward the feedthrough assembly.
