Tag Archives: Choosing a Sensor

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.

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.

Measuring the temperature of plastic preforms in blow moulding applications is easy with Calex infrared temperature sensors. An accurate measurement can be obtained as fast as 1 millisecond, even from the smallest preform, without touching the preform.

Calex has achieved success in measuring the surface temperature of extruded aluminium profiles using low-cost non-contact pyrometers. Measurements were taken by a leading manufacturer of extruded profiles at the press exit and after the quench, and good results were obtained with short-wavelength single-wavelength pyrometers, even with significant steam near the quench box.

Most infrared temperature sensors have an adjustable emissivity setting. Here’s how to use this powerful feature to achieve accurate measurements from a variety of surfaces.
