Temperature sensors and temperature transmitters are devices used to measure and monitor temperature, and they have some differences in function and application.
A temperature sensor is a sensor device used to measure temperature. It can convert temperature into corresponding electrical signal output for temperature monitoring and control. Common temperature sensors include thermocouples, thermal resistors (such as platinum resistors), semiconductor sensors, etc. Temperature sensors are usually mounted directly on the measurement object and sense temperature changes through physical or electrical effects, converting them into electrical signal output. The output signal of a temperature sensor is usually an analog signal whose value is proportional to the temperature.
A temperature transmitter (Temperature Transmitter) is a device that converts the analog signal measured by the temperature sensor into a standard signal output. It receives the analog signal from the temperature sensor and converts it into a standard signal, such as a 4-20mA current signal or a 0-10V voltage signal. Temperature transmitters are commonly used in industrial automation control systems to transmit temperature information to devices such as data collection devices, controllers or Recorders. By using temperature transmitters, analog signals can be converted into standard signals to achieve long-distance transmission and anti-interference capabilities of signal transmission.
Therefore, the main difference between a temperature sensor and a temperature transmitter is its function and the form of the output signal. A temperature sensor is responsible for measuring and sensing temperature and converting it into an analog signal output, while a temperature transmitter converts an analog signal into a standard signal output for transmitting and monitoring temperature information. In the field of industrial automation, temperature sensors and temperature transmitters are often used in combination to achieve accurate temperature measurement and long-distance transmission. ...
