Abstract
An elongated heat detection device identifies heat sources based upon infrared radiation. The device includes a purged and sealed instrumentation chamber and a rugged and shock absorbing case. The case surrounds and protects the chamber and includes anti-roll features. The instrumentation is provided in a forward end of the device and is capable of being plugged into the balance of the device for rapid repair and replacement. The power supply is contained in a rear end of the device and the case forms a portion of the power supply circuit. The device employs a startup test of the sensor and the power supply. Also, the power supply is continuously monitored. The device also employs a lost device locator such that the device can be readily located after being misplaced. Moreover, the device has a signal expanding feature that allows a heat source that is rapidly passed over to be relocated on subsequent sweeps of the device.
