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.

Technical advice from Calex Electronics on choosing a suitable infrared temperature sensor to measure small targets.  

In this video, Anthony Smith introduces the PyroNFC, the world’s first NFC-compatible infrared temperature sensor. The sensor has configurable voltage and alarm outputs, and is compatible with Android phones with NFC. Watch this video to find out about the main features of the sensor and the app.
