Calex needed to expand its product range in order to increase its market share. The development of low carbon technologies was a key to its success. The non-contact temperature measurement in high ambient temperatures without cooling was identified as an application. Calex required university expertise in analogue electronic design, electromagnetic shielding techniques and electrical noise limitation. The main objective of the project was to design a new infrared temperature sensor that would enable a significant reduction in carbon emissions to be achieved by both Calex and its customers.

Calex Electronics Limited designs and builds infrared temperature sensors for a wide range of manufacturing activities, including food, paper, automotive, plastics, glass and metals. Calex serves the UK, EU and worldwide markets.


Anglia Ruskin University, along with the project associate Jiaqing Shao, provided essential expertise and aided the development of a novel infrared temperature sensor, branded as PyroMini. The sensor is capable of measuring very small infrared signals remotely without compromised accuracy. A small and cost-effective sensor head can be installed at an ambient temperature over 1800ºC without an additional cooling system, allowing the PyroMini to be used in a wider range of applications. This high-temperature capability was combined with innovative new features including a built-in touch screen interface, data logging and alarm relay outputs.

It is envisioned that this new project will enable a significant reduction in carbon emissions to be achieved by sensor manufacturers and users. Therefore the objectives of this project will be fully met.

“The project has been a resounding success. The new sensor gives customers a great opportunity to improve their energy efficiency and Calex a significant edge over its competitors.”
