Industrial thermometers are crucial for precise temperature measurement in various sectors. They come in diverse types, catering to specific requirements, such as contact or non-contact measurement.
Thermometers are crucial to monitor and ensure that the temperature does not exceed or go beneath required limits in several industries. This serves critical functions such as:
To adequately serve these functions, industrial thermometers come in different types, such as:
These industrial tools constantly take readings and display the result on a digital display unit. Due to their accuracy, efficiency, and ease of reading, they stand out among the industrial tools. They could be contact or non-contact, although most contact types have probes and sometimes infrared technology for non-contact ones.
As one of the digital thermometers, infrared thermometers gauge temperatures remotely by measuring the thermal radiation emitted from the surface of an object. This tool is generally employed in situations where it is either unsafe or impractical to come in direct contact with objects. The metal, glass, or other surfaces may be too hot or hazardous to check physically. Infrared gauges work well in metallurgy, HVAC calibration, and checking power lines. Their quickness makes them appropriate for monitoring temperatures in dynamic systems from a safe distance. Often known as laser thermometers, infrared thermometers are effective, efficient, and safe industrial tools.
Although commonly found in the past, these glass thermometers with mercury are gradually being replaced with more advanced models. These are valuable in limited application areas such as laboratories and chemical industries due to their traditional crystal accuracy and simplicity of use. Excessive or low temperature where the glass can break or mercury spills are some of the dangers of using this kind of thermometer.
With two different metallic wires intertwined, this temperature measurement device is among the most widely used thermometers due to flexibility. A voltage is generated when the wires form a junction, providing a temperature measurement at that point. Known for their extensive temperature range and quick response time, these gauges are suitable for extreme conditions. Industries such as oil and gas, food processing, and chemical manufacturing use them to measure the temperature of fluids, gases, and even machinery.
Thermometers gauge temperature through metal strip expansion. The strips are selected because one bends more than the other when heated. As much as they are less utilized due to the availability of thermophones with more efficiency and advantages, they are still useful in monitoring the temperature of steam and gas in industrial equipment.
These contain metallic coils, usually platinum. They are very precise and stable, which makes them suitable for measuring basic and critical temperature ranges. It is especially suitable for the chemical industry and power production due to its robustness in extreme environments. As much as they are more accurate than thermocouples, their application is limited because of the intricacy and cost involved.
These are also very accurate and can withstand severe conditions. They employ a corundum crystal, which changes its individual properties to measure the degree accurately. Their strength and accuracy make them ideal for high-parameter systems in difficult environments, such as space exploration and deep-sea applications. In situations where failure is not an option, such as aerospace or nuclear power, sapphire gauges are essential.
As previously stated, industrial tools are now available in many types. Nonetheless, there are some features of industrial thermometers that are relatively constant regardless of type. These are the physical features or how manufacturers build thermometers.
This is the range in which an industrial thermometer works to measure temperature. Most thermometers have a wide range to measure varying degrees. However, some thermographers are built to serve specific temperature ranges. For example, sapphire gauges are for extreme temperatures, whereas mercury and gas bimetal thermos for low to moderate.
Accuracy refers to how close the readings are to the actual temperature. In contrast, precision refers to the grade of steadiness upon emission of the same result after several measurements. Generally, high-end industrial tools are accurate to within a few tenths of a degree. However, as they are built for different industrial applications, their accuracy may differ. For instance, infrared gauges are accurate within ±1°C, while RTDs can manage ±0.1°C.
It is the period an industrial thermometer takes to read the temperature. Generally, the response time may differ based on the tool's design and how it is constructed. Nonetheless, it generally ranges from a few seconds to minutes. Usually, thermocouples and infrared instruments have shorter response times. On the other hand, bimetals and RTDs are slower than laser thermos.
Considering that most industries work in tough or hazardous environments, thermoregulators are durable. For example, those made from sapphire crystal and thermocouples often have exceptional gauges. In addition, many of these tools are moisture, dust, and shock-resistant.
As technology increases, so are the industrial thermometer features. For example, many digital gauges allow users to log temperature records and connect to other smart industrial devices. Some also have mobile applications for instant accessibility. This is particularly useful in complex processes where constant monitoring is critical. As much as this feature is not standard, it is present in several infrared and digital thermometers.
Industrial thermometers are available in various types and serve different uses in various industries. Below are some of the commercial value or market application of these thermograph types.
