Uses of Spring Thermocouple

The sensor probes of spring-loaded thermocouples are made of a metal or alloy sheath and a spring. This is one of the most important types of mineral-insulated thermocouples. It has a spring that helps the process and the tip makes good contact. This positive contact will help speed up the sensor’s response time and give a more accurate temperature reading. So, it is used a lot in situations where accurate temperature measurement is needed. Therm-x sells thermocouples with springs that can be used with thermowells. They are also great for uses that need spring to work. There are many spring thermocouple manufacturers you can find online. Among all these spring thermocouple manufacturer, our website will provide you with good quality product at reasonable prices. 

What are some good things about spring-loaded thermocouples?

Therm-x makes spring-loaded thermocouples that are used in many different industries. They also work perfectly in applications that use gas or a vacuum. These thermocouples are better than other types because they have the following features.

When used with thermowells, the spring-loaded tip and threaded bushing make for a close fit and repeatability.

Our spring-loaded thermocouples come with two different types of protection heads, so they can meet a wide range of size and environmental needs.

The high integrity of these mineral-insulated thermocouple sensors makes them a good choice for a wide range of temperatures.

Both the pressure on the head of these spring-loaded assemblies and the pressure around the probe are the same. This helps make sure that the pressure on both sides is balanced.


We can make these MI thermocouples to fit the needs of your application. They have a spring-loaded terminal block that makes it easy to connect them to any terminal head. Here are a few things about our customization services.

Spring-loaded thermocouples are made with threaded spring-loaded bushings that work well in all situations.

They come in sizes J, K, and T and can be sheathed in either 316 SS or Inconel 600. The sheath diameters are.125Eo and.062Eo. We can also make them in types besides J, K, and T if you want.

On request, the type K thermocouple wire can have different error limits put on it.

Both the hole for the extension wire and the thread on the spring-loaded probe are 1/2 NPT.

The standard thermocouple junctions for these thermocouples can be ungrounded, grounded, or exposed.

These thermocouples with a spring can be bought in non-sealed versions that work great for thermowells.
