Infrared sensors provide an easy and accurate way of measuring the temperature of moving cylindrical objects in industrial processes. Calenders, rolls, rotating tubes and pipes have traditionally been difficult to measure using contact probes such as rolling thermocouples. The thermocouple tip rubs against the surface and must often be replaced; the response time is too … Continue reading Rollers, Pipes and Cylinders Non-Contact Temperature Measurement →

If your application involves measuring a small target, you should ensure that the measured spot size of the infrared temperature sensor is small enough. Otherwise, it may be difficult to obtain an accurate measurement. We typically recommend that the measured spot size should be half the target size or smaller for best accuracy. For example, … Continue reading Infrared Temperature Measurement of Small Targets →

The PyroCV Series of infrared temperature sensors is ideal for measuring the temperature of the road surface before and after asphalt is laid. It is is specifically designed for use on construction machinery and has been tested to EMC requirements for these environments. It provides simple, robust, non-contact temperature measurement with either CAN communications or … Continue reading Asphalt Temperature Measurement in Road Laying using the PyroCV Infrared Temperature Sensor →

Infrared temperature sensors are often installed in locations where accurate temperature monitoring is critical to production and quality. In many applications, operators need to view the same temperature readings from multiple locations without relying on a SCADA system. A PyroMini infrared temperature sensor can be supplied with a dedicated display for local visualisation. Often, the … Continue reading Multi-Display Temperature Measurement System →

We are pleased to announce that Errol Thomas .Jr has recently been promoted to Quality Director at Calex Electronics. Below, we highlight his journey with the company, his new role, and a little about his interests outside work.

The following application notes highlight a number of applications where temperature monitoring may be required in hazardous areas. In these environments, contact temperature measurement can present challenges. We highlight how our ATEX-certified non-contact infrared temperature sensors, such as ExTemp and ExTempMini, may help overcome these challenges.

Paint curing processes in spray booths require accurate and consistent temperature control to ensure optimal coating adhesion, finish quality, and durability. Temperature detection across vehicle surfaces is critical to achieving uniform curing, particularly on complex geometries and large panels.

As previously mentioned, when Calex transitioned to an Employee Owned Trust at the end of last year, our former Managing Director Gary Fuller planned to retire after 29 years at Calex. That day finally came at the end of March, when the team said “goodbye” and presented Gary with a selection of leaving gifts, namely … Continue reading It’s official! →

In some applications, it may not be practical to install an infrared temperature sensor directly inside the process. This can include applications where contamination must be eliminated or where hazardous conditions are present. In these cases, an IR transmissive viewport window can be used to isolate and protect the sensor from the application or target … Continue reading Measuring Temperatures Through Viewport Windows →

In the following video, we briefly introduce the Excelog 6 and show how to use it with our free Excelog software to log temperatures directly to your PC. The video also guides you through the software interface and highlights its main features.
