Capillary tube analog capillary thermometer

In analog capillary thermometers, capillary tubes connect the measuring point to the scale. These thin tubes play a crucial role in reliably transmitting temperature changes.

Functions of capillary tubes

• Transport medium: Capillary tubes link the measuring sensor to the dial and transmit temperature changes through a medium, such as liquid or gas, that expands or contracts with fluctuations.
• Construction: Capillary tubes are thin and flexible, usually made of metal (commonly stainless steel) or plastic. Additionally, you can fit them with a casing to protect them from external influences.
• Flexibility: Capillary tubes allow you to position the measuring point and the dial separately. This setup works well for hard-to-reach or hazardous areas.
• Precision: Capillary tubes transmit temperature changes quickly and accurately to the dial, ensuring precise readings every time.

Features and options

Manufacturers typically make capillary tubes from metal or plastic, giving them high durability and resistance to wear. Moreover, they come in different lengths to suit a wide range of applications. For extra protection, you can choose a stainless steel sleeve. Our specialists can help you select the options that best fit your system.

The difference between capillary tubes and stems

In a capillary thermometer, capillary tubes and stems work together to provide accurate measurements and easy-to-read displays. The tube transmits temperature changes from the sensor to the dial, while the stem protects the tube or acts as a sensor itself.
