XDB701 Temperature Transmitter: Ensuring Accurate Temperature Measurement Through Proper Insertion Depth

Temperature sensors are widely used in various industries to measure and control temperature. However, the insertion depth of temperature sensors is often overlooked. The insertion depth of a temperature sensor can significantly affect its accuracy and stability. Therefore, it is crucial to understand how to calculate the proper insertion depth for temperature sensors.

In general, the insertion depth of a temperature sensor can be determined based on the specific requirements of the application. However, the minimum insertion depth should not be less than 8-10 times the diameter of the protective sheath of the temperature sensor to ensure stability and accuracy. Some customers may require a shorter insertion depth but with a larger diameter, which is not recommended, especially for high-temperature applications.

To calculate the proper insertion depth of a temperature sensor, it is essential to ensure that the sensitive part of the sensor is fully immersed in the medium being measured to achieve accurate temperature measurement. The required immersion length for temperature sensors is as follows:

A. For measuring gases, the insertion depth should be greater than 95mm for thermocouples and greater than 115mm for resistance temperature detectors and bimetallic temperature sensors.

B. For measuring liquids, the insertion depth should be greater than 46mm for thermocouples, resistance temperature detectors, and bimetallic temperature sensors.

C. The insertion depth of a temperature sensor is equal to the length of the connecting head plus the thickness of the pipe wall plus the immersion length.

D. If the process pipeline diameter is too small (less than 80mm), it is necessary to make an expansion pipe for installing the temperature sensor.

E. For temperature measurement in general tower equipment, a horizontal installation of the temperature sensor with an insertion depth of 300-400mm is sufficient. For temperature measurement in boiler furnaces, the temperature sensor is typically installed horizontally, and the immersion length needed is only 150mm, excluding the thickness of the furnace refractory bricks.

The XDB701 Temperature Transmitter is specifically designed to ensure accurate temperature measurement by maintaining proper insertion depth. It features a robust construction and advanced technology that allows for easy installation and reliable operation. With its accurate and stable performance, it is an excellent choice for various temperature measurement and control applications.

In conclusion, the insertion depth of a temperature sensor is a critical factor that affects its performance and accuracy. By following the proper guidelines for calculating the insertion depth, you can ensure accurate temperature measurement and reliable operation of the temperature sensor. The XDB701 Temperature Transmitter provides an optimal solution for accurate and reliable temperature measurement in various industrial applications.
