| Raytek Corporation, a leading supplier of non-contact temperature measurement solutions for industrial applications, has recently introduced two new infrared temperature sensors with a fibre optic assembly rated to 315�C, ensuring their ability to withstand high-temperature industrial environments, without the need for water cooling. They have been designed to resist strong electromagnetic fields, which can interfere with measurement accuracy. The sensors� fibre optic cable, one of the highest rated temperature cables available on the market, enables the heat resistant sensor to be snaked around obstacles, and keeps the sensor�s electronics, housed separately, to be located away from sources of heat.
Ideal for the continuous, fixed temperature monitoring of stationary and moving targets, Raytek�s Marathon FA one-colour fibre optic sensor measures temperatures between 475� and 3,000�C. The Raytek Marathon FR two-colour, or ratio sensor measures temperatures between 500�C and 2,500�C of objects partially obscured by smoke, dust and steam, or which are smaller than the field of view. Raytek DataTemp� software is available for the networked control of multiple sensors and easy acquisition, display and organisation of temperature data. The stainless steel sensor housing can be equipped with optional air purge to keep the lens free of dust or condensation. Laser sighting for marking measurement targets is also available optionally. Applications include temperature monitoring of glass furnaces, fore-hearth and gob measurement, glass moulds and plunger temperatures, casting and foundries, blast furnaces, hot strip mills and rolling mills, heat treating and annealing, laser welding and others.
