A-1325 / A-1326 Intake Air Temperature Sensor (IAT) Thermometrics A-1325/A-1326 Temperature Sensor monitors the temperature of the incoming intake air flow for an engine and provides a signal output that is proportional to air temperature. This signal can be used as an input to a temperature gauge, or to provide input to an Engine Control Unit (ECU). The ECU then uses this information to adjust fuel delivery and optimize the air-to-fuel ratio to produce the most efficient combustion. Applications Features Intake Air Temperature High accuracy and long-term stability Integrated sealed connector Typical Application Circuit Existing field-proven design 280 Source Alternate geometries/connection systems 5 V to meet package requirements 150C max operating temperature V out T Pre-applied thread sealant Other resistance and beta values possible Amphenol Advanced SensorsA-1325 / A-1326 - Specifications Operating Temperature Range R vs. T -40C to 150C Temp.
