New compressed air counter testo 6440
Lowering costs by consumer allocation
Compressed air is a profitable, but also very costly energy source. If the high costs are only allocated as a “cost block”, those responsible for the systems have no motivation to try and lower costs. However, if the compressed air consumption of each system is recorded individually, the person responsible for the system is motivated to reduce leakage and to employ consumption-saving measures. The newly developed testo 6440 provides optimal support here, in that it has a built-in totaliser function. The total consumption can be read directly from the instrument or registered in the regulating system via consumption impulses. Consumption-dependent switch outputs are alternatively also available, which can monitor maximum consumption either time-dependently or time-independently.
Over 96% of leakages occur in DN50 (2”) pipes and smaller. Leaky hoses, fittings, connections and maintenance units are mainly responsible for this. Installed in front of an individual machine or a machine group, the testo 6440 can detect even the smallest compressed air volume flows. These indicate leakage if they occur during machine downtime.
Peak load management helps to avoid extended investments
Growth can be expensive: Expanding industrial enterprises are forced to expand their compressed air production too. A peak load analysis on the basis of compressed air counters helps to avoid such investments. Since it is known when which consumption occurs, the existing and planned consumption can be distributed over a daily / weekly profile so that the existing capacity of compressed air production is sufficient. The result is considerable savings in the compressors as well as in the pipe system.
Protecting valuable compressed air consumers from too high or too low supply
Compressed air consumers require a minimal supply in order to provide the desired performance. Some consumers additionally have to be protected from too high a supply. In critical cases, the warranty of the system’s manufacturer is even dependent on this. The testo 6440 performs both monitoring tasks optimally thanks to its two switch outputs. For the continuous protection of your investment.
The optimal measurement principle for compressed air flow measurement is thermal mass flow measurement. Only this is independent of process pressure and temperature and does not cause a lasting loss of pressure. Two glass-coated ceramic sensors, developed specially for demanding compressed air applications, are exposed to the process temperature and linked in a Wheatstone bridge.
