Abstract

The embodiment of the invention discloses a sensor, a measurement and control system and an aircraft. The sensor comprises a probe, a signal converter and a voltage conversion circuit, wherein the probecomprises a platinum resistor used for sensing the environment temperature and generating a temperature signal, and a silicon-sapphire pressure sensitive core body used for sensing environment air pressure and generating a pressure signal; the signal converter comprises a conditioning circuit which comprises a temperature signal conditioning circuit and a pressure signal conditioning circuit, and a temperature compensation circuit which is used for compensating a second voltage signal output by the pressure signal conditioning circuit through a first voltage signal output by the temperature signal conditioning circuit; and the voltage conversion circuit is used for converting the first voltage signal and the second voltage signal into voltage signals required by the measurement and control system.

Description

technical field [0001] The invention relates to the field of sensors. More specifically, it relates to a sensor, a measurement and control system and an aircraft. Background technique [0002] A sensor is a device that can convert the sensed information into an electrical signal or other required form of output according to a certain rule. It is an important part of the measurement and control system, especially in aviation and aerospace measurement and control systems. Temperature sensors and pressure sensors have a large number of applications. , is the nerve ending of the measurement and control system that sensitively measures the temperature environment parameters and pressure parameters, and plays an important role in the health monitoring and control of the aircraft. [0003] With the rapid development of aviation and aerospace vehicle technology, the flight speed of the aircraft is getting faster and faster. At the same time, the integration and miniaturization of i...
