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.
Modbus is a communication protocol for networks of devices, including Calex infrared temperature sensors such as the PyroMiniBus. Our own specialised hardware makes it easy to take measurements and configure sensors without any programming knowledge, however it is also possible to use third-party software to communicate with Modbus devices. A little understanding of Modbus is … Continue reading How to Use Third Party Modbus Software with Calex Sensors
A handheld infrared thermometer is a useful diagnostic tool. Here are some tips on how to achieve accurate measurements, and how the handheld thermometer can be used to find out if a planned installation of fixed-mount sensors could be successful.
How do you know if your infrared temperature sensor is aimed correctly? Here are some easy ways to improve the alignment of your pyrometer.
Advancements in the Calex product range make it easier than ever to measure the temperature of busbar joints in switchgear cabinets.
The lens of every infrared temperature sensor must be kept clean and dry to ensure the pyrometer has a clear view of the target. The simplest way to do this is to purge the lens continuously with clean air, preventing dust and moisture from reaching it. Here is how to use the air purge collar.
