Quick and easy to install in place of a traditional thermocouple probe, the PyroNFC-K miniature infrared temperature sensor has been announced by Calex Electronics.

The PyroMiniUSB, a new USB infrared temperature sensor from Calex Electronics Ltd, makes non-contact temperature measurement in benchtop, laboratory and education applications easier and more accessible than ever before. This low-cost miniature sensor measures surface temperature with 1°C accuracy and with an instantaneous 125 ms response time.

The new PyroNFC from Calex Elecronics is a small, low-cost infrared temperature sensor that lets engineers and machine operators use a smartphone app to check temperature measurements on the production line. The PyroNFC sensor measures the temperature of surfaces in industrial processes without contact, and at just 29 mm in length, it is the smallest sensor that Calex has ever produced.

The new PyroMini 0.9 infrared pyrometer makes it possible to measure the temperature of reflective metals and semiconductors, as low as 350°C, at low cost and without contact.  The pyrometer can view into a vacuum chamber through a quartz or glass window, and measure the temperature of the surface of the silicon wafer.

Calex has introduced the Pyromini infrared temperature sensor for applications where precise temperature control is needed and forming temperatures typically range from 120°C to 370°C.  The plastic sheet is heated by infrared heaters; a temperature sensor is used for each heating zone to ensure it is heated evenly. For the best control, at least 10 points should be measured: all four corners and the centre, on the top and bottom surf...

The new PyroMini infrared pyrometer from Calex Electronics is packed full of exciting new features. Its miniature sensing head measures just 18 mm x 45 mm, making it ideal for mounting in tight spaces. A high ambient version is capable of withstanding temperatures of up to 180°C without water or air-cooling, allowing significant energy and cost savings to be made.

Calex has designed a temperature monitoring and alarming system for a leading flour milling company to help prevent fires and explosions. Grain passes through rollers that grind it into flour. The roller separation is finely adjusted; if they are too close together, excessive heat is generated by friction, which can cause the roller temperature to become critically high. The flour dust can then ignite, causing a fire or a devastating explosion. A...

Calex has been approached by a leading manufacturer of food processing equipment with a specific requirement for non-contact infrared temperature measurement. The CI5234, a special sensor based on the existing two-piece PyroCouple M, is designed specifically for this customer's requirements. It has features that also make it ideal for many other applications.

Infrared temperature sensors from Calex Electronics have been used with success for over 7 years. When a gas cylinder is filled and the pressure increases, the cylinder will warm up. The temperature of the surface is monitored for several reasons:

Infrared temperature sensors from the Calex PyroCouple Series are being used by a major tyre manufacturer to detect the presence of hot rubber tyre material as it passes a point on a conveyor. The tyre material is transported in two thin bands on a cooled aluminium conveyor. A Calex PyroCouple model PC301MT-0 infrared temperature sensor is positioned above the conveyor, and is aimed so that both bands are contained in its field of view.

The all new PyroUSB 2.2 non-contact temperature sensors detect infrared radiation at wavelengths between 2.0 and 2.4 microns. This short-wavelength method of measurement allows much greater accuracy, and improved tolerance of optical obstructions or errors in emissivity setting, than longerwavelength sensors.
