The invention belongs to the technical field of aviation, and relates to a novel icing signal sensor. The novel icing signal sensor comprises a socket, a contact point, a static pressure chamber, a diaphragm capsule, a dynamic pressure chamber, a static pressure hole, a pipe end heater, air inlets, a power source, an elbow shell and a signal lamp, wherein the air inlets are formed in the head portion of the novel icing signal sensor, and communicated with the dynamic pressure chamber, and the dynamic pressure chamber bears the total pressure of airflow flowing through the air inlets; the static pressure hole is formed in the side of the sensor, and communicated with the static pressure chamber, and the static pressure chamber bears the static pressure of airflow flowing through the static pressure hole; the pipe end heater is arranged behind the air inlets, and heat of the pipe end heater can be transmitted to the air inlets through heat conduction and can conduct heating de-icing operation on the air inlets; the diaphragm capsule is an electric conductor, stretching and withdrawal of the diaphragm capsule are automatically adjusted through the difference of pressure, inside and outside the diaphragm capsule, of the static pressure chamber and the dynamic pressure chamber, the diaphragm capsule and the contact point are connected and disconnected to control energization and de-energization of the signal lamp and the pipe end heater, and when a circuit is connected, the air inlets are heated to remove ice through the pipe end heater.
