此文档已被声明为“非当前”。因此，建议本文件不适用于新设计。“非现行”是指以前被广泛引用的文件，并且可能在某些现有设计中继续需要这些文件。本SAE航空航天标准（AS）涵盖两种基本类型的温度仪表，如下所示:I型:比率计型，由感温电阻元件的电阻变化驱动；通过感温电阻元件的温度变化获得电阻变化。II型:毫伏表型，由热电偶的不同电动势输出操作和驱动；通过温度传感热电偶的温度变化获得仪器的不同EMF输入。本文件确立了主要用于涡轮驱动亚音速运输机的电气式温度仪表的基本最低安全性能标准，其运行可能会使仪表受到第3节规定的环境条件的影响。 4.

This document has been declared "NONCURRENT". It is recommended, therefore, that this document not be specified for new designs. "NONCURRENT" refers to those documents which have previously been widely referenced and may continue to be required on some existing designs.This SAE Aerospace Standard (AS) covers two basic types of temperature instruments as follows: type I: ratiometer type, actuated by changes in electrical resistance of a temperature sensing electrical resistance element; the resistance changes being obtained by temperature changes of the temperature sensing resistance element. Type II: millivoltmeter type, operated and actuated by varying EMF output of a thermocouple; the varying EMF input to the instrument being obtained by temperature changes of the temperature sensing thermocouple.This document establishes the essential minimum safe performance standards for electrical type temperature instruments primarily for use with turbine powered subsonic transport aircraft, the operation of which may subject the instruments to the environmental conditions specified in Section 3.4.
