Additionally a warning can be issued, when the thermal inspection tool detectes a temperature that is too high or too low. For the definition of the monitored plant areas different selection areas can be used. Besides the standard circle and rectangle, users can choose a freely oriented rectangle and a freely definable polygon to define an arbitrary number of inspection windows. This can be set as a single window or merged as a logical combination of areas. The Smart Thermal Inspector offers 6 digital outputs which can be transmitted individually using standard communication protocols such as Profinet or free TCP/IP communication. What’s more, several cameras can be connected to the Smart Thermal Inspector for complex temperature monitoring. Built-in statistics allows to keep track of different measurement readings and get the trend results. An optional gray-/color image capture extension allows users to capture and evaluate gray scale and color images in addition to the thermal images. An example would be a label with serial number, expiration date or codes (OCR, DMC, QR, bar code), which cannot be captured with thermal imaging.
