1. An ice detector probe receiving selective energization for sensing ice deposition from an air mass moving relative to and impinging upon the probe comprising:

  • mounting means for installation of the probe to receive a flow of the air mass;

    thermal means disposed on the mounting means,the thermal means including a sensing surface oriented to receive impingement of the air mass and having a thermal member receiving the selective energization for heating the sensing surface and for also sensing a temperature of the sensing surface, the thermal member further providing an output representative of the temperature of the sensing surface sensed by the thermal member during the time the selective energization of the thermal member is operative to heat the sensing surface to melt ice, the output representative of the temperature sensed indicating the ice deposition; and

    wherein said thermal member comprises a protective member having a thin film platinum resistance thermometer deposited on the protective member in a batch fabrication process.
