The dual temperature PT25 sensor supplies high pressure compressor (HPC) inlet temperature data to the EEC. The EEC uses the T25 temperature information to control these components: Transient bleed valve (TBV) Variable bleed valve (VBV) Variable stator vanes (VSV). The PT25 sensor has two electrical connections that supply data to both EEC channels. 用途 PT25 传感器将将高压压气机进口温度信号送到EEC, EEC利用PT25来控制如下部件: 瞬态放气活门TBV 可变放气活门 VBV 可变静子叶片 VSV PT25 传感器有两个插头分别连到 EEC 的两个通道。 The PT25 sensor is at the 6:00 position on the inner wall of the fan frame under the fan duct panel. 位置 PT25 传感器位于风扇框架内环上6 点钟位置风扇排气管盖板下。 There are two platinum elements in the PT25 sensor assembly. One element is for channel A, the other is for channel B.The EEC supplies a constant voltage power supply to the PT25 sensor elements. The elements change resistance to the electrical current in proportion to air temperature. The different output voltages from the platinum elements goes to the EEC. The EEC measures the difference between the constant output voltage and input voltage from the sensor. The EEC converts the difference into a HPC inlet temperature. 功能描述 PT25传感器组件中有二个铂金元件(铂金电极)。 一个元件用于通道A，另一个用于通道 B。EEC向PT25 传感元件提供一个恒定电压电源。元件将阻值转换成与空气温度成正比的电流。
EEC 测定恒定输出电压和来自传感器的输入电压之间差值。EEC 将差值转换成HPC 进口温度。 |
