Description / Abstract:
SCOPE:
This SAE Aerospace Standard (AS) applies to all temperature
instruments used in aircraft
applications and environments. The word "instrument" as used in this
Standard encompasses only the
display device and does not include the temperature sensors. Examples
of the types of instruments
covered are as follows:
Temperature instruments using a Resistance Temperature Detector
for temperature sensing.
Temperature instruments using a thermocouple for temperature
sensing.
Temperature instruments using an averaging thermocouple harness
for temperature sensing.
Temperature instruments receiving an input from a signal
conditioning unit.
Temperature instruments receiving an input from another
temperature instrument.
Temperature instruments receiving an input from other temperature
sensing devices.
Purpose:
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.
