这里介绍的光纤温度传感器可以不用机电滑环把信号从一个旋转连接面传递到另一个连接面。它是通过非接触光学滑环,把旋转轴上的光学信号传递到静止的测量电路。这种非接触光学连接方式适用于高速旋转(例如,涡轮机),而热电偶和其他的电温度传感器都需要接触连接才能传递电信号,因此旋转速度受到限制。 The fiber optic temperature sensor described here can transfer signals from one rotating connection to the other without the electromechanical slip ring. It is through the non-contact optical slip ring, the optical axis of the optical signal is passed to the static measurement circuit. This non-contact optical connection is suitable for high-speed rotation (eg, turbines), and thermocouples and other electrical temperature sensors require a contact connection to transmit electrical signals and therefore rotational speed is limited.
