XDB701 Temperature Transmitter: Understanding the Difference Between Heat Dissipation Rods and Heat Dissipation Plates

Temperature transmitters are essential instruments in industrial process temperature measurement and control. They convert temperature variables into standardized output signals that can be transmitted and interpreted by controllers. However, the rate at which they dissipate heat can significantly affect their performance and accuracy. To address this issue, there are two common ways to dissipate heat from temperature transmitters: heat dissipation rods and heat dissipation plates.

So, what is the difference between heat dissipation rods and heat dissipation plates?

For temperature ranges below 300℃ and with the same length, heat dissipation plates are more effective than heat dissipation rods. Heat dissipation plates have a larger surface area in contact with the air, resulting in better heat dissipation performance.

For temperature ranges above 300℃, particularly above 500℃, and with no length requirements, heat dissipation rods are more effective than heat dissipation plates. Heat dissipation plates have limited processing quantities, usually not exceeding ten pieces, and come with high processing costs. Moreover, their heat dissipation performance decreases as the temperature increases. Heat dissipation rods, on the other hand, are simple to process, cost-effective, and have no length restrictions, ranging from a few millimeters to several centimeters. They can keep the circuit board away from the heat source, ensuring that the amplification board is not affected by the temperature.

The XDB701 temperature transmitter is an example of a high-quality temperature transmitter that uses heat dissipation rods to ensure stable and reliable performance. It is designed to operate in harsh industrial environments, with a temperature range of -50℃ to 200℃, making it suitable for a wide range of industrial applications.

The XDB701 temperature transmitter is easy to install and use and comes with features such as high measurement accuracy, fast response time, and excellent stability. It uses a 4-20mA current signal to transmit the temperature measurement data, making it easy to integrate with other control systems. It also has a compact and robust design, making it resistant to vibration and shock.

In conclusion, selecting the appropriate heat dissipation method is crucial to ensure the accurate and reliable performance of temperature transmitters. Heat dissipation rods and heat dissipation plates have their advantages and disadvantages, and the selection depends on factors such as the temperature range, size, and cost. The XDB701 temperature transmitter is an excellent example of a high-quality temperature transmitter that uses heat dissipation rods to ensure stable and reliable performance in harsh industrial environments.
