Logika

The Logika Technologies through-beam Optical Barrier OB-VT is designed for automation of steel, aluminum, and other production lines characterized as having extreme industrial environments. The OB-VT is used to detect the presence of product throughout the steel making process or any area with an extreme environment, particularly around furnaces.

The OB-VT is a two-piece instrument comprised of an Emitter and a Receiver. The emitter contains a solid-state laser diode that penetrates dust, steam and high temperatures around reheat furnaces. The Receiver picks out the modulated light from the optical noise of the steel plant for reliable product detection. Both Emitter and Receiver have built-in water cooling and air purge capability.
