Pressure, temperatureand positioningMany arduous processes require accurate temperaturemeasurement or the monitoring of pressure. Having theright controls in place enables companies to achievemini mal maintenance, near-zero downtime and enhancedfinished product quality.Process temperature monitoringFluctuations in temperature provide an early indication of variationin process conditions. It is vital that temperature movements aremonitored continuously, not just to maintain product quality butalso to avoid damage to production equipment. The smooth runningof operations is safeguarded by measuring temperature in theprocess at points such as the preheater tower, the kiln, the clinkercooler, the coal mill, electrostaic precipitator and clinker silo.Siemens offers a range of temperature transmitters,suited for use in a number of process environments:■ Remote mounting capability allows isolation from hightemperatures and vibration sources■ Local display and local programming■ Advanced communications and predictive maintenancefunctions enable optimisation of maintenance cycles
Pressure Temperature Valve positioningAccurate process responseHydroclassification of pure silica sand is critical for a variety ofhigh-grade industrial operations such as float glass, fused silicaand quartz crystal lenses. Hydroclassifiers use water pumped at afixed rate from the bottom while sand is added from the top. Theupward water flow causes the lighter sand to pass out at the topwhile heavier sand sinks to the bottom to be removed by a valvefor subsequent drying and transport. The valves on the water inputand the classifier outlet must be able to respond to small processand pressure changes respectively.1415SIPART PS2 valve positioner■ Suitable for both inlet and outlet valve positioning tasks,offering a range of advantages when used to controlthe hydroclassifier■ Compatible with both rotary and linear actuators, enablingstandardisation on one device, saving costs relating to trainingand spare parts■ Advanced diagnostics including predictive maintenanceallow operators to plan maintenance in advance of failure■ Local or remote set-up possible on every unit■ Robust design for the primary industriesIntelligent cleaning cyclesExhaust air filtration systems depend on regular cleaning of filtersand equipment. Most dust collectors clean or backwash the filtersat pre-determined times irrespective of whether the filters needcleaning. As well as wasting plant air and increasing energy costs,the increased strain on the filter reduces its life. Indeed, a certainamount of caking can increase filter effectiveness by trapping thefiner particles passing through.SITRANS P pressure transmitter■ Provides data for an intelligent cleaning cycle by measuringthe pressure differential between the clean and dirty sideof the bag filter, enabling cleaning to be based upon actualrequirements■ 100 to 1 turndown allows standardisation with one pressuresensor suitable for a variety of applications■ Local display and programming capabilities■ Predictive maintenance functions enable maintenance prior todevice failure
