Claim:
1. A fluid leak detector for detecting and alerting of leakage in a pressurized fluid system having a closed conduit with an inside, an outside, and a fluid within having an ambient temperature, the fluid leak detector comprising: a first sensor in thermal communication with the outside of said conduit and capable of sensing the ambient temperature of said fluid; a second sensor in thermal communication with the outside of said conduit and responsive to a drive signal to elevate a temperature of said second sensor to an elevated temperature; a controller in communication with said first sensor and said second sensor configured to sense said ambient temperature from said first sensor and generating said drive signal to drive said second sensor to said elevated temperature greater than said ambient temperature and to generate a trip signal when said drive signal of said second sensor exceeds a trip point value; and an audible alarm in electrical communication with said controller configured to receive said trip signal from said controller and to activate an audible alert in response thereto.
