HOT METAL POSITION DETECTOR(HMPD) VMH-200

Sensors for special applications Iron and Steel Industry

Wide range output voltage! This device consists of a camera and a controller and detects the infrared ray from the hot metal and outputs the analog signal.

Feature

• CCD camera system is applied and 2 pcs of camera can be connected to 1 pce of controller
• Analog output can be displayed with 7 segment LED on the controller. Current analog value can be read directly.
• Waveform of camera can be displayed with maintenance mode by connecting PC. It is possible to check light-reception level or influence by disturbance light.
