Temperature non-contact
In many production and processing facilities, operations take place at high temperatures. Proper automation and quality control require safe detection and monitoring of temperatures without contact.
Infrared heat sensors absorb the heat radiation of objects and convert it into a switching signal. The advantage of having no mechanical contact between the object and the sensor makes infrared sensors ideal for temperature monitoring applications, such as moving objects in spaces with difficult access, conductive or sticky objects/materials, surface treated objects, or on aggressive media where short response times are required, dangerous applications for direct contact.
Sigma Hellas provides high quality, cost effective, non-contact temperature measurement solutions for inaccessible or moving objects and materials in industrial, benchtop, laboratory and educational applications
