Cost-effective alternative in pressurised systems up to 10 bars: SS 20.261
The creation of compressed air is a cost-intensive process. It will therefore pay you to optimize the compressed-air networks. The first step is the knowledge how and where the optimization can be made.
The basis for the system optimization is the precise and continuous analysis of the compressed-air system's actual consumption. To calculate this, the operator must know the actual volume flows of the system, the distribution of the compressed air in the network and, finally, also the volume flows during the idle periods - the leakage quantities. This data will help you to plan the optimization measures which have to be taken. The solution is: the use of volume flow sensors. They measure all the required data such as leakage quantities, consumption and distribution to the individual consumers (for a unambiguous cost allocation). This may help to adjust the maintenance intervals to the actual status of the system.
Application examples
· Packing machines
· Injection moulding machines
· Textile machines
· Pneumatic conveyance system
· Surface coating
· Installation of compressed-air tools
· Production of insulating material
The thermal flow sensor SS 20.261 works by the hot wire principle of a thermal anemometer. That's why the application in systems with overpressure is very simple since only the temperature and pressure values must be measured and calculated. The sensor measures the correct flow velocity independently of the pressure (up to 10 bars). The linear output signals of flow and temperature are individual current signals 4 ... 20 mA – from 0 m/s to 40, 60 or 90 m/s. The measured value is output as standard velocity which can be converted easily in the volume flow of the used tube diameter.
