Sensors, transmitters, signal isolator of the differences and relations

Sensor is a kind of testing device, can feel the measured information, and will feel information, according to certain rules transform into electrical signal or other required information in the form of output, in order to meet the needs of information transmission, processing, storage, display, record and control requirements. Sensors including temperature sensor, such as thermal resistance, thermocouple. Pressure sensor. Flow sensor and transmitter is the sensor output signal into recognition of signal can be controller ( Or will the sensor input non-electricity converted to electrical signals and zoom to signal for distance measurement and control) The converter. Sensor and transmitter together constitute the monitoring signal source of automatic control. Different physical quantities need different sensors and the corresponding transmitter. Many different kinds of transmitter, used in industrial control instrument mainly have the transmitter temperature transmitter, differential pressure transmitter, pressure transmitter, liquid level transmitter, flow transmitter, current transmitter, voltage transducer, power transmitter, etc. Signal isolator is the input signal, such as current signals, voltage signals, thermal resistance, thermocouple signal, analog output isolation linear current or voltage signal, and improve electrical isolation between input, output, power performance. 传感器之间的区别和联系,发射机和信号isolatorsSensor是一种检测装置,它可以测量信息意识和感觉到的信息转换成电信号或其他所需形式的信息输出按照一定的规则来满足信息传输的要求,处理、存储、显示、记录和控制。 传感器包括温度传感器,如热电阻和热电偶。 压力传感器。 流量传感器等。 发射机是一个转换器,将传感器的输出信号转换成一个信号被控制器( 或者将非的信号源 电传感器的输入电信号放大它的远程测量和控制) 。 传感器与发射机在一起形成一个自动监测信号来源。 不同的物理量需要不同的传感器和相应的发射器。 有许多种类的发射器。 主发射机用于工业控制仪器温度变送器、差压变送器、压力变送器、液位变送器、流量变送器、电流传感器、电压传感器、功率发射机等等。 信号隔离器将输入信号,如电流信号、电压信号,热电阻信号,热电偶信号等。 线性电流或电压信号,输出隔离,之间的电气隔离性能和改善输入、输出和电源。
