Temperature measurement in an industrial setting involves using specialized tools and instruments designed to provide precise and reliable temperature monitoring across a variety of environments, which may include extreme heat or cold, exposure to corrosive substances, or applications in which direct contact with the measured surface isn’t possible or desirable.
This includes two basic classes of temperature measurement sensors, including contact sensors and non-contact sensors.

Contact sensors, such as resistance temperature detectors (RTDs), thermocouples, and bimetallic thermometers, are characterized by their requirement to physically touch the material being observed.

Non-contact sensors, on the other hand, don’t require physical contact with the surface, making these sensors great for applications that involve fragile and easily damaged materials. Infrared sensors are among the most common non-contact sensors that detect the thermal radiation emitted by an object, allowing the sensor to determine the temperature without physical touch.

Industrial thermometers work in pretty much the same way as consumer ones. However, the accuracy rating associated with industrial-grade equipment is often higher compared to consumer goods.

• Thermocouples: These devices rely on the Seebeck effect, where a voltage is generated at the junction of two different metals with different thermal coefficients. The change in voltage is proportionate to the change in temperature. Thermocouples are durable and operate at a wide temperature range, making them perfect for industrial settings.
• RTDs: Resistance temperature detectors’ resistance changes with the temperature fluctuations. They’re quite accurate and stable, which is why they’re often used in industrial processes that require very precise temperature control. It stands to reason, of course, that they’re also pricier than thermocouples. But they’re also significantly more accurate.
• Infrared thermometers: Infrared thermometers pick up the infrared energy emitted by the surface of an object. Infrared isn’t a visible spectrum; instead, it’s perceived as heat. Much in the same way, the heat also generates IR radiation, which is picked up by these sensors. This allows non-contact temperature measurements, which is particularly important for applications in which the sensor can’t physically touch the measured surface.

Temperature, in an industrial context, isn’t just a number on a scale; it’s a rather crucial parameter that indicates the status of a particular process, the condition of a product, or the health of the equipment used in operation. Thus, temperature measurement in an industrial setting must be precise, repeatable, and reliable—such data is often used in feedback systems for process control. A good example of this is automated control of heating elements or cooling systems inside the manufacturing or supply chains.
