    Industrial overhead-crane synchronization & automation

    The over-head crane has 2 arms, which are to be synchronized for filling hot liquid aluminium in the furnace.
    The assembly involves 2 incremental shaft encoders, which are coupled with the DC motors. The position of individual crane is as per the setting done on the controller. Each arm is first positioned as per the sequence. The vessel containing the hot liquids are tilted to be filled in the furnace.

    Level-volume controller of liquid-filled tanks.

    To determine the amount of liquid present in the tank, the Ultrasonic transmitter is used. This generates a 4 to 20mA output signal, which is given to instrument. The display indicates the height of the liquid in the tank. By using the volume formula, the volume of the liquid is also displayed. The retransmission output related to volume is given out for SCADA software package for further processing.

    Load-cell based powder-filling machine control:

    The costly powder material cannot be filled in the sacks by volume, it requires weight-based measurement.
    Here the load-cell is used for precision weight measurement. The load-cell signal is digitized by 16 bit / 24 bit ADC's. The hopper, contains a powder to be filled, has a crew, which is controlled by clutch & brake assembly. The VFD controls the speed of filling.

    Thus hardware requires the Analog input & digital outputs along with the timers for continous cycle.

    Phosphine Gas Treatment of Wheat:

    Wheat is treated with phosphin gas for a period of 15 days continously before it is stored in the ceilos. This ensures a proper storage of wheat for a long duration. For each of the 15 days, the wheat is treated for a pre-specified quantity of phosphin gas. This is achieved by using the analog output, the gradual opening & closing of the valve. The gas saturation in the chamber is measured using a sensor through Analog input. also included are timers, interlocks.

    Stretch controller for Denim

    The denim cloth material is required to be stretched before being processed. This is done by controlling the tension between the load roll & take-up roll. The load roll & take-up roll has incremental shaft encoders connected to it. The settings are done in such a way that the position of both rolls is adjusted as per the desired stretching of the denim material.
