What is an industrial thermometer?

You’re reading the next “What is…” blog. This edition is about industrial thermometers. The industrial type of thermometers is used for measuring temperatures in the industrial sector. After reading this blog, several things are discussed to make sure you know all the ins and outs of industrial thermometers. Starting with why to use an industrial thermometer, followed by the types of industrial thermometers.

Why use an industrial thermometer in the first place?

Before diving into industrial thermometers in specific, let’s first talk about why to use a thermometer in the first place. Since industrial thermometers are pretty different from regular thermometers, it’s helpful to point out why to use an industrial thermometer instead of the one you use for measuring the temperature in for example your home. Industrial thermometers are way more stable than regular thermometers. They are very accurate and have a long lifespan. This is due to the fact that they don’t have any mechanically moving parts, which means no material fatigue and no consumption of electrical energy.

How does an industrial thermometer work?

An industrial thermometer is filled with liquid. The higher the measured temperature, the more this liquid inside expands. The expanding liquid results in its climbing inside the tube. This way, the temperature can be read on the display next to the tube.

Differences in industrial thermometers

Industrial thermometers come in different shapes and forms. One of the things in which they differ is the angle at which the immersion tube is attached to the thermometer itself. For different situations, different angles of attachment may be necessary. Industrial thermometers come in the next angles:

The immersion tubes we just discussed can also differ from each other. They differ in material. These materials are:

  • Steel.
  • Stainless steel.
  • Brass.
  • Special brass.
  • Copper-nickel alloy.
