PERMANENT INSTALLATION NON-CONTACT TEMPERATURE SENSORS & MONITORS

In many 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 responce times are required, dangerous applications for direct contact.
