本SAE航空航天标准（AS）适用于飞机应用和环境中使用的所有温度仪表。本标准中使用的“仪器”一词仅包括显示设备，不包括温度传感器。所涵盖仪器类型的示例如下:1.1使用电阻温度检测器进行温度传感的温度仪器；1.2使用热电偶进行温度传感的温度仪表；1.3使用平均热电偶线束进行温度传感的温度仪表；1.4接收信号调节装置输入的温度仪表；1.5接收另一温度仪表输入的温度仪表；1.6接收其他温度传感装置输入的温度仪表。本文件规定了主要用于飞机的电气式温度仪表的基本最低性能要求，这些仪表可能会受到本文规定的环境条件的影响。

This SAE Aerospace Standard (AS) applies to all temperature instruments used in aircraft applications and environments. The word "instruments" as used in the Standard encompasses only the display device and does not include the temperature sensors. Examples of the types of instruments covered are as follows: 1.1 temperature instruments using a resistance temperature detector for temperature sensing; 1.2 temperature instruments using a thermocouple for temperature sensing; 1.3 temperature instruments using an averaging thermocouple harness for temperature sensing; 1.4 temperature instruments receiving an input from a signal conditioning unit; 1.5 temperature instruments receiving an input from another temperature instrument; and 1.6 temperature instruments receiving an input from other temperature sensing devices.This document establishes the essential minimum performance requirements for electrical type temperature instruments primarily for use on aircraft which may subject the instruments to environmental conditions specified herein.
