传感器在机械工程测试中的应用研究
摘要
在工业生产过程及工程检测中, 为了对各种工业参数（如压力、温度、流量、物位、位移等）进行检测与控制, 首先要把这些参数转换成便于传送的信息, 这就要用到各种传感器, 把传感器与其它装置组合起来, 组成一个检测系统或调节系统, 完成对工业参数的检测与控制。
本文主要介绍传感器在机械工程测试中的应用，包括温度测量、压力测量、流量测量、物位测量等。
关键词：传感器温度测量压力测量流量测量物位测量
APPLICATION OF SENSOR IN MECHANICAL ENGINEERING TEST
ABSTRACT
In the process of industrial production and engineering testing, in order to various industrial parameters (such as pressure, temperature, flow, level, displacement etc.) to detect and control, first take these parameters into convenient delivery information, it is necessary to use a variety of sensors, the sensor and its device combination, a detection system or control system, complete the detection and control of industrial parameters。
This paper mainly introduces the application of sensors in mechanical engineering testing, including temperature measurement, pressure measurement, flow measurement, and location measurement.
Key words: sensor /temperature measurement /pressure measurement /flow measurement
/object position measurement
