Transmitter concept
2011-9-29 17:22:28

     A transmitter is a sensor that outputs a standard signal. 侯也 与传感器通用。 The term is sometimes used in common with sensors.
很多, 总体来说就是由变送器发出一种信号来给二次仪表 使二次仪表显示测量 数据。 There are many types of transmitters . In general, the transmitter sends a signal to the secondary meter , so that the secondary meter displays the measured data. 普通电信号 转换为标准电信号输出或 能够以通讯协议方式输出的设备。 A device that converts a physical measurement signal or a common electrical signal into a standard electrical signal output or can be output in a communication protocol. Generally divided into: temperature / humidity transmitter, pressure transmitter , differential pressure transmitter , liquid level transmitter , current transmitter, power transmitter, flow transmitter, weight transmitter and so on .
者叫 实验数学模型 ,就是 将物理量的变化转化成4-20mA 等标准信号的装置。 The transmitter follows a physical law or experimental mathematical model , which is a device that converts changes in physical quantities into standard signals such as 4-20mA . The transmitter converts the sensing signal into a unified standard signal: 0 / 4-20mADC, 1-5VDC, 0-10VDc . 有传感的功能之外 同时 还有放大整形的功能,输出为标准的控制信号 In addition to the sensing function, the transmitter also has the function of amplifying and shaping, and the output is a standard control signal .
