Hokuyo - VMH200
Hot Metal Position Detector - HMPD
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.
