11J Temperature Sensor for Home Air Conditioners

Application

Air Conditioners

Refrigeration Temperature Sensor Series: The 11J series NTC thermistor temperature sensor is primarily used in refrigeration equipment requiring wide-range temperature measurement. This series offers low cost, reliable performance, and high accuracy, clearly advantageous compared to traditional bimetallic thermostats limited to one or two temperature points. The 11J sensor's thermistor is highly sensitive, changing resistance rapidly with temperature. Combined with electronic circuitry, it allows continuous temperature monitoring over a broad range.

Application Areas: # Refrigeration system temperature sensing # Freezer compartment temperature sensing # Other general-purpose equipment

Product Features: # High reliability # Low cost # Single integrated design # Fast response

Principle of Operation: An NTC thermistor is a semiconductor ceramic made from various metal oxides, whose resistance decreases as temperature increases. Controlled by corresponding electronic circuits, it measures ambient temperature. Unlike bimetallic thermostats providing both sensing and control, the thermistor acts solely as a temperature sensor; electronic control is handled by the connected circuitry.
