A gauge having a self danger-indicating function is provided to reduce the installing costs by removing a separate system for central control and to improve efficiency by the filed manager multi-tasking. A gauge having a self danger-indicating function includes a case(18), a temperature sensing device(20), a compass needle(19), a sensor, a controlling unit, a power unit, and a danger displaying unit. The case has a temperature display plate. The temperature sensing device senses penetrated one side of the case, and senses the temperature. The compass needle is rotated by the quantity sensed by the temperature sensing device, and points the scale of the temperature displaying plate. The sensor senses whether the compass needle approached on the predetermined spot. The controlling unit is applied with the signal sensed by the sensor. The power unit supplies power to the controlling unit. The danger displaying device is applied with the controlling signal from the controlling unit after being applied with the signal from the sensor, and displays danger to the filed manager.
