Customers looking for a low-cost system to measure up to eight surface temperatures and display the readings on a digital indicator should consider the Calex PyroMiniBus Infra-Red Temperature Sensor, supplied with a Pixsys STR571 indicator.

Customers looking for a simple, low cost solution to measure surface temperature and display the reading on a digital indicator or controller should consider the Calex PyroCouple Infra-Red Temperature Sensor, supplied with a Pixsys ATR124 indicating controller.

Calex has successfully measured the temperature of a sintered steel gear using an 8-14 µm general-purpose sensor.

For accurate results when using an infrared temperature sensor (pyrometer), the emissivity setting must be correct. Here are some methods to help you find the right setting to use.

Powerful processing features are available on many Calex infrared temperature sensors as standard. Learn more about these features, and some of the sensors that provide them.

Calex short wavelength (2.0 to 2.6 µm) infrared temperature sensors are suitable for accurately measuring the surface temperature of non-metals and some metals at high or low temperatures. These sensors have adjustable emissivity settings, reflected energy compensation and peak and valley hold processing, making them particularly suitable for measuring hot objects in a furnace or on … Continue reading Comparison of Short Wavelength Infrared Temperature Sensors →

Blackbody calibration sources from Calex allow the calibration of infrared temperature sensors with low uncertainty. This article explains what makes the best blackbody calibration source for a given application and what you should consider when choosing one. 

Infrared temperature sensors are commonly used in industry to control aspects of the process such as heaters, cooling systems and line speed. One of the simplest ways to measure temperature without contact and obtain a control output is to use a Calex PyroCouple pyrometer and a low-cost indicating controller such as the ATR121. Here’s how.

Calex can supply protective windows for pyrometers, and IR-transmissive viewport windows. This brief summary aims to help you to choose a suitable window. Protective Windows Protective windows, such as PWS and PWL, are ideal for use in the food and pharmaceutical industries. They protect the lens of Calex infrared temperature sensors by preventing contamination and/or … Continue reading Which Viewport Windows are Suitable for Calex Infrared Temperature Sensors? →

Calex normally recommends using a short-wavelength infrared temperature sensor to measure the temperature of metals, instead of a general-purpose type, because it is more accurate. But why is it more accurate? Here are the reasons.
