The Best Way to Measure the Surface Temperature of a Metal
Non-contact Temperature Measurements Temperature is a critical factor in many processes and must often be measured accurately. Non-contact infrared measurement is often the better alternative for this as compared to physical thermocouple measurements. Temperature...
What is Emissivity and Reflectivity?
What is Emissivity? Not all surfaces are the same. Depending on what you’re pointing your infrared temperature sensor at you’re likely to get variations in emitted infrared energy. This variation is called emissivity. Emissivity is a measure of a material’s ability to...
Are Non-Contact Thermometers as Accurate as Contact Thermometers?
A Contact or Non-Contact Approach? Non-contact temperature sensors such as infrared pyrometers are relied upon for their unique ability to monitor temperature and dictate process control in a multitude of manufacturing processes. The non-contact approach offers an...
What Temperatures Ranges Do Infrared Thermometers Accurately Measure?
What is an Infrared Thermometer? Infrared thermometers sometimes called temperature guns, laser thermometers, or pyrometers are non-contact temperature sensors that can be used in a wide range of manufacturing processes to accurately measure the temperature of a given...
The Difference Between Two-Color and Dual-Wavelength Pyrometers
Editor's Note: This blog post was originally published in 2015 and has been updated for accuracy and relevance. In the world of infrared temperature sensors, there are two types ofratio pyrometers: Two-Color (TC) and Dual-Wavelength (DW). Both use a ratio of energy...
Top 7 FAQ for Aluminum Extrusion Temperature Measurement
Editor's Note: This blog post was originally published in 2013 and has been updated for accuracy and relevance. Aluminum has traditionally been thought of as a difficult-to-measure-material with an infrared pyrometer because it is so reflective and has unique...
Pyrometer or Thermocouple For My Aluminum Process?
Whenever we sell a pyrometer to an aluminum mill we start the conversation by telling the customer that the two of us are having an argument, but that we just don’t realize it yet. We then go on to tell them that the way to resolve this argument is to seek the truth....
Traditional vs. Fiber-Optic Pyrometers
Williamson is the leading manufacturer of accurate non-contact temperature sensors or pyrometers. Fiber-optic pyrometers offer a distinct advantage over their traditional counterparts because of their ability to be used in tight areas and survive harsh...
Why Should I Use an Infrared Pyrometer to Measure Temperature in My Process
Infrared pyrometers are excellent devices to use when a direct contact measurement may not be possible. Often times the things we are trying to measure are simply too hot for contact devices like thermocouples or resistance thermometers. In addition, the things we are...
4 Ways to Reduce the Cost and Time of Research and Development
Research and development planning plays a key role in the continued progress of the steel industry through the discovery of more efficient and effective production processes and the creation of high-quality, value-added steel products. The development of better...
