需要能够在恶劣环境中工作的高温传感器，以防止由于温度升高而导致的结构或系统功能故障造成的灾难。大多数现有的温度传感器不能满足需求，因为它们需要物理接触或电池电源进行信号通信，此外，它们都不能承受高温或旋转应用。本文提出了一种新型无源无线温度传感器，适用于工作在恶劣环境下的高温旋转部件监测。完全无源LC谐振遥测方案依赖于频率变化输出，已成功应用于压力，湿度和化学测量，与独特的高k温度敏感陶瓷材料集成，以便在传感器内无触点，有源元件或电源的情况下测量温度。本文基于机械和电学建模，以最大化传感距离、Q值和灵敏度为目标，对高温传感器进行了设计和性能分析。最后，在235°C的温度范围内，成功制作了传感器样机并进行了标定，验证了无源无线通信温度传感的概念。
High temperature sensors capable of operating in harsh environments are needed in order to prevent disasters caused by structural or system functional failures due to increasing temperatures. Most existing temperature sensors do not satisfy the needs because they require either physical contact or a battery power supply for signal communication, and furthermore, neither of them can withstand high temperatures nor rotating applications. This paper presents a novel passive wireless temperature sensor, suitable for working in harsh environments for high temperature rotating component monitoring. A completely passive LC resonant telemetry scheme, relying on a frequency variation output, which has been applied successfully in pressure, humidity and chemical measurement, is integrated with a unique high-k temperature sensitive ceramic material, in order to measure the temperatures without contacts, active elements, or power supplies within the sensor. In this paper, the high temperature sensor design and performance analysis are conducted based on mechanical and electrical modeling, in order to maximize the sensing distance, the Q factor and the sensitivity. In the end, the sensor prototype is fabricated and calibrated successfully up to 235°C, so that the concept of temperature sensing through passive wireless communication is proved.
