    OB-VR


    1. Logika’s visible laser optical barrier (OB-VR) is designed for automation of steel, aluminium and other metal mill production lines. This optical barrier is used primarily to detect hot and cold metals. Typical applications include dummy bar detection, thin plate, billet and slab. The OB-VR uses a high powered modulated laser as the light source. The reflector returns the laser light to the optical barrier where it is converted to an electrical signal. The reflector can operate in temperatures as high as 250˚C (480˚F).

  • PM SERIES


    1. The PM series of pyrometers PM616 and PM3514 are designed exclusively for use in metal industries, our instrument is calibrated to function with the highest accuracy under the worst conditions. This one sensor can be implemented starting at the caster, all the way to the coiling of sheet. The PM series can accurately measure the surface temperature of liquid steel, slabs, billets, blooms, bars and wire rod and is an invaluable tool in process and quality control. Engineered to reduce reading errors by compensating for factors such as emissivity, dust, mist, scale or obstructions in the field of view.
