Laser camera sensors and pin actuators for melt level control
MQP are introducing the Moduloc high resolution digital laser camera and motor operated pin actuator unit for accurate control of molten aluminium level in launder and mould to less than 0.5mm. (Fig.10)
The digital laser camera sensors enable a much narrower trigonometric angulation angle to be used. This means that the camera and laser can be mounted together in an exceptionally compact housing (180 x 164 x 62mm) positioned well above the molten metal surface.
The pin and gate valve actuators which control the molten metal pour incorporate DC motor drives and 4-20ma position feed back; providing smoother continuous movement.
