Alarm device for liquid circulation system
First Claim
1. An alarm device for use in a liquid circulation system, comprising:
- an optical detection unit that generates electronic signals in accordance with the intensity of light beam penetrated through a transportation media of the liquid circulation system;
a decision circuit electrically coupled to the optical detection unit for excerpting the electronic signals generated from the optical detection unit and generating a control signal when the transportation media is in an abnormal state; and
an alarm electrically coupled to the decision circuit for generating an alert message in accordance with the control signal from the decision circuit.

Abstract
An alarm device for use in a liquid circulation system. The alarm device includes an optical detection unit, which includes an optical emitter that generates light beam to penetrate through a transportation media of the liquid circulation system, and an optical receiver that is positioned opposite to the optical emitter for receiving the light beam penetrated through the transportation media. The alarm device further includes a decision circuit, which is electrically coupled to the optical receiver for excerpting therefrom electronic signals corresponding to the intensity of light beam received by the optical receiver. The decision circuit further determines whether the transportation media is in a normal state. If the transportation media is in an abnormal state, a control signal is generated to drive the alarm sending out alert messages. The alarm device described above is assembled in a box and is securely installed to a predetermined position of the transportation media of the liquid circulation system.
