How many dual temperature sensors are located in each wing's anti-ice system?

In the anti-ice system of each wing, there are two dual temperature sensors. These sensors play a crucial role in monitoring and controlling the temperature within the anti-ice system to ensure effective performance. Having dual sensors allows for a more accurate and reliable assessment of the temperature, which is critical in preventing ice formation on critical aircraft surfaces. This redundancy enhances safety, as it provides a backup measurement in case one sensor fails or operates outside expected parameters. This design is particularly important in aviation, where ice accumulation can severely impact aircraft performance and safety during flight.
