In summary, digital temperature transmitters are devices used to measure temperature and convert it into digital signal output.

Common types of digital temperature transmitters include:

  1. RTD (Resistance Temperature Detector) Type: Based on the principle of resistance varying with temperature, often utilizing platinum resistance thermometers (e.g., PT100, PT1000) for higher accuracy and stability.

  2. Thermocouple Type: Utilizes the thermoelectric potential difference between two different metals to measure temperature, suitable for high-temperature environments with fast response times.

  3. Semiconductor Type: Based on semiconductor materials like silicon or silicon carbide, characterized by fast response times, small size, and relatively lower cost.

  4. Infrared Type: Measures temperature by detecting the infrared radiation emitted from the surface of an object, suitable for non-contact temperature measurement, such as high-temperature surface measurement.

Technical features include:

  • High Accuracy: Typically offering high measurement accuracy to meet precise requirements in various applications.
  • Digital Output: Converts temperature into digital signals for easy connection to various digital systems for processing and control.
  • Strong Anti-interference Capability: Digital signal transmission usually possesses strong anti-interference capability, ensuring stable operation in harsh industrial environments.
  • Temperature Compensation: Some digital temperature transmitters feature temperature compensation functions to automatically calibrate in response to temperature changes.

Digital temperature transmitters find applications in various fields including:

  • Industrial Automation: Used for temperature monitoring and control in industrial production processes such as chemical, pharmaceutical, and food processing industries.
  • Environmental Monitoring: Utilized in fields like meteorology and environmental protection for temperature monitoring.
  • Energy Sector: Employed for temperature monitoring and control in power plants, nuclear power stations, and other energy-related equipment.
  • Healthcare: Utilized in medical equipment for temperature monitoring, such as thermometers.
  • Automotive Industry: Applied in components like car engines and gearboxes for temperature monitoring and control.
In summary, digital temperature transmitters are devices used to measure temperature and convert it into digital signal output. They are characterized by high accuracy, digital output, and strong anti-interference capability, and are widely applied in industrial automation, environmental monitoring, healthcare, and other fields.
