Spring holder / Rotating holder thermocouple for extruder

spring holder or rotating holder thermocouple is a type of temperature sensor commonly used in extruders, which are machines used to melt and shape plastic or other materials.

The thermocouple is a type of sensor that measures temperature by using the principle of thermoelectric effect. It consists of two dissimilar metals that are joined together at one end. When there is a temperature difference between the two ends of the metals, a voltage is generated, which can be measured and used to determine the temperature.

The spring holder or rotating holder thermocouple is designed to be inserted into a small hole in the extruder barrel, where it can measure the temperature of the material as it is being melted and extruded. The spring holder or rotating holder refers to the mechanism used to hold the thermocouple in place and prevent it from moving or vibrating during operation.

The spring holder thermocouple uses a spring mechanism to hold the thermocouple in place, while the rotating holder thermocouple uses a rotating mechanism to keep the thermocouple steady. Both types of thermocouples are commonly used in extruders and other high-temperature applications where precise temperature control is necessary.
