INDUSTRY COMPONENT

Temperature Sensor

Temperature sensor for automotive active grille shutter systems that monitors coolant/air temperature to optimize engine thermal management and aerodynamics.

Component Specifications

Definition
A precision electronic component integrated into automotive active grille shutter (AGS) systems that continuously measures coolant or ambient air temperature. It provides real-time data to the vehicle's engine control unit (ECU) to regulate shutter opening/closing, balancing engine cooling requirements with aerodynamic efficiency. This sensor enables intelligent thermal management by adjusting airflow through the radiator based on operating conditions.
Working Principle
Operates on the thermistor principle (typically Negative Temperature Coefficient - NTC) where electrical resistance changes predictably with temperature variations. The sensor's resistance decreases as temperature increases, converting thermal energy into measurable electrical signals. These analog signals are transmitted to the ECU via voltage dividers or digital communication protocols (like LIN or PWM) for processing and shutter actuation decisions.
Materials
Housing: PA66-GF30 (30% glass-filled polyamide) for thermal stability and chemical resistance. Sensing element: Ceramic-encapsulated NTC thermistor chip (Mn-Ni-Co oxide). Electrical contacts: Gold-plated brass pins. Seal: EPDM rubber gasket (IP67 rating). Cable: PVC-insulated copper wires with high-temperature silicone coating.
