Programmable controllers monitor and regulate pressure and flow of the gas transmission and distribution systems,data is gathered and measured in the field and transmitted to the PLC system.
PIPELINE AND PUMP STATION CONTROL The PLC control machines and booster pump for crude oil distribution.it measures flow suction, discharge and tank low and high limits,possible communication with SCADA (Supervisory control and data acquisition) system can provide total supervision of the pipeline.
OIL FIELDS:The PLC provides on side gathering and processing pertinent to characteristics such as depth and density of fluid for drilling rigs.The PLC control and monitor the total rig operations and alert the operators of any possible malfunction.
GLASS PROCESSING:The PLC controls the lehr to remove the internal stress of glass products.This system controls the operation by the following: i)the annealing temperature curve during the reheating,annealing straining and rapid cooling process through different heating and cooling zones,improvement are made in the ratio of glass to scrap reduction in labour cost and energy utilization
GLASS BATCHING: The programmable controller controls the batch weighing according to the store glass formular (s).The system also controls the electromagnetic feeders for in-feed to and out feed from the weighing hoppers,manual shot-off gates,and other equipment.
CULLET WEIGHING: The PLC directs the cullet system by controlling the vibratory outlet feeder,weight belt scale and shuttle conveyor.All sequences of inventory of the quantities weighted are kept by the PLC in future use,
BATCH TRANSPORT: The PLC also control the batch transport system including reversible belt conveyors,transfer conveyors to the cullet house, holding hoppers,shuttle conveyor,and magnetic seperators. The controller, takes action after the discharge from the mixer and transfer the mixed batch to the furnace shuttle, where it is discharged to the full length of the furnace field hopper.
