The aircraft temperature sensors market size is expected to see strong growth in the next few years. It will grow to $0.35 billion in 2030 at a compound annual growth rate (CAGR) of 6.1%. The growth in the forecast period can be attributed to increasing adoption of electric aircraft and advanced air mobility, rising demand for battery thermal management, growing use of predictive aircraft maintenance, increasing demand for high-precision temperature sensing, and expansion of next-generation aircraft platforms. Major trends in the forecast period include advanced temperature sensing technologies, miniaturization of aircraft temperature sensors, high-accuracy temperature measurement, real-time aircraft thermal monitoring, and high-temperature sensor durability.

The growing air passenger traffic is expected to propel the growth of the aircraft temperature sensors market in the coming years. Air passenger traffic refers to the movement of travelers through commercial aviation networks for domestic and international transportation. Air passenger traffic is rising due to increasing tourism, as more people are traveling for leisure, business, and international experiences, leading to higher demand for air travel. Rising air passenger traffic drives demand for aircraft temperature sensors by increasing aircraft production, fleet expansion, and the need for advanced temperature monitoring systems that ensure accurate measurement and control of engine, cabin, avionics, hydraulic, and environmental temperatures to enhance aircraft safety, performance, and operational efficiency. For instance, in January 2026, according to the International Air Transport Association (IATA), a Canada-based trade association, global air passenger demand increased by 5.3% year-on-year in 2025, measured in revenue passenger kilometers (RPKs), while passenger capacity rose by 5.2%, indicating continued growth in global air traffic. Therefore, the growing air passenger traffic is driving the growth of the aircraft temperature sensors market.

Major companies operating in the aircraft temperature sensors market are focusing on developing advanced temperature sensing solutions, such as platinum resistance temperature detector (RTD) sensors, to improve temperature measurement accuracy, reliability, and engine performance across modern aircraft systems. Platinum RTD sensors refer to temperature-sensing devices that use the predictable resistance change of platinum with temperature to provide accurate and stable temperature measurements. For instance, in June 2025, Curtiss-Wright Corporation, a US-based aerospace and defense technology company, expanded its aerospace sensor product family through the addition of Weed Instrument temperature sensor solutions following its acquisition of Ultra Energy. The solutions are designed for next-generation aircraft and use proprietary platinum RTD technology for accurate and reliable temperature measurement. They support aircraft engines, fuel systems, and air management systems, enhancing engine control, performance, and efficiency.
