500 to 2000°C
For ferrous and non-ferrous metals, induction heating, ovens, laboratory research.



Built for use in harshest environments, the Thermalert sensor withstands ambient temperatures up to 85 °C (185 ºF) without extra cooling. The sensor supports many wavelengths and can be used for a broad range of application.


Designed to handle wider temperature ranges this sensore comes with superior in class optical resolution. 2-wire loop powered RS-

485 as well as digital (Ethernet, EtherNet/IP, PROFINET IO) and analog outputs are available to meet your process requirements. Galvanic insulation ensures correct readings.


  • Sensors are rugged, small and easy to install 
  • Laser sighting available for all instruments
  • Backward compatibility to old Raytek® and Ircon® in class sensors and accessories
  • Broad range of accessories available (high temperature enclosures, cables,…)
  • 2-year warranty
