How to distinguish between sensors and transmitters?

Sensor and transmitter are key components in the field of electronics and automation. They are used to detect, measure and convert physical quantities or environmental parameters, and convert this information into electrical signals for processing or control by electronic systems. Both sensors and transmitters play a key role in automation, monitoring and control systems.

Both sensors and transmitters are used to collect data on physical quantities or environmental parameters. Sensors measure these parameters and generate corresponding electrical signals, while transmitters are responsible for converting the analog signals output by the sensors into standard electrical signals for further processing.

One of the objectives of sensors and transmitters is to monitor the status of the environment or equipment in real-time. They provide continuous updates on information such as physical quantities, pressure, temperature, humidity, light intensity, etc., so that control or alarm measures can be taken in a timely manner.

Sensors convert physical parameters into electrical signals, while transmitters convert the analog signals output by the sensors into standard signals such as current or voltage signals. This conversion allows the signals to be transmitted to remote locations or further processed.

Sensor and transmitters can be selected based on the specific application requirements and specifications. They are capable of adapting to various environments and conditions, including temperature, humidity, pressure, and vibration.

The use of sensors and transmitters can improve the stability and reliability of automation systems. They ensure the accuracy and consistency of data, which helps to reduce system failures and maintenance efforts.

Sensors and transmitters can be used in feedback control systems to automatically adjust and maintain the operation of equipment. For example, temperature sensors can monitor temperature changes and adjust heating or cooling systems accordingly.

Although sensors and transmitters have many similarities, there are also some key differences between them. The main difference is that sensors are used to measure and generate electrical signals of physical parameters, while transmitters are used to convert and amplify these signals to better adapt to the needs of remote monitoring and control systems. Sensors typically provide raw data, while transmitters provide processed and standardized signals. Therefore, they are often used in conjunction with each other to achieve a complete monitoring and control solution.
