BA05-AI/I integrated current transmitter

A transmitter is a converter that converts the output signal of a sensor into a signal that can be recognized by a controller (or converts the non electric input of the sensor into an electrical signal while amplifying it for remote measurement and control). Sensors and transmitters together form the monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters. There are many types of transmitters, and the ones used in industrial control instruments mainly include temperature transmitters, pressure transmitters, flow transmitters, current transmitters, voltage transmitters, and so on.BA05-AI/I integrated current transmitter

The transmitter has a Chinese name, and its English name is Transmitter

As the name suggests, a transmitter contains the meanings of "change" and "send".

The so-called 'change' refers to the transformation of various physical quantities from sensors into an electrical signal. For example, using thermocouples to convert temperature into electrical potential; Using a current transformer to convert high current into low current. Due to the ease of processing electrical signals, modern transmitters convert various physical signals into electrical signals. Therefore, when we talk about transmitters, they usually become "electric".

The so-called 'sending' refers to the process of unifying various electrical signals that have been converted into sensors through electronic circuits (such as 4-20mA) for the purpose of facilitating the reception and transmission of other instruments or control devices. The method is achieved through multiple operational amplifiers. This combination of "change" and "send" forms the commonly used transmitter in modern times.

For example, SST3-AD is a current transmitter that converts the output current of a current transformer into a standard 4-20mA current; For example, SST4-LD can convert the weight signal from the weight sensor into a standard 4-20mA weight transmitter. [1]
