Manage capacity and reduce compressed air costs
July 27th 2006

with the New Testo 6440 Compressed Air Counter Compressed air is a costly resource. If an organisation has no knowledge of compressed air consumption by department, process or machine it can make cost allocation difficult and does not motivate the organisation to look at methods to reduce leakage or consumption. The new Testo 6440 is a compressed air counter that enables organisations to accurately monitor compressed air usage to assist in managing costs and plan resource allocation.

SUPERIOR DESIGN FOR ACCURATE MEASUREMENTS

The Testo 6440 measures mass flow to guarantee correct measurements and is unaffected by the effect of fluctuating pressure conditions and temperatures. In four diameter sizes, the Testo 6440 offers a compact design coupled with integrated high-performance technology, which provides all necessary signal outputs. The built-in inflow and outflow pipes guarantee optimum accuracy and the thermal glass coated ceramic sensor offers robustness and fast reaction times.

LOWERING COSTS BY CONSUMER ALLOCATION

The Testo 6440 can be used to measure the consumption of compressed air by individual department, process or machine. When compressed air consumption of each system is recorded individually in this way, the person responsible for the system is motivated to reduce leakage and to employ consumption-saving measures. The Testo 6440 provides optimal support here, with 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 also available, which can monitor maximum consumption either time-dependently or timeindependently.

LEAKAGE DETECTION

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 and can indicate any leakage occurred during machine downtime.

PEAK LOAD MANAGEMENT HELPS TO AVOID EXTENDED INVESTMENTS

Growth can be expensive, forcing industrial enterprises to also expand their compressed air production. Peak load analysis on the basis of compressed air counters can help to avoid such investments. By knowing when 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.

MANAGE COMPRESSED AIR SUPPLY TO ENSURE PRODUCT QUALITY AND PROTECT EQUIPMENT

It may be necessary for a continuous minimum or maximum compressed air supply to be maintained in order to ensure product quality or protect equipment.

The Testo 6440 performs both monitoring tasks effectively thanks to its two switch outputs, ensuring the continuous protection of your investment.

Testo 6740 Pressure Dew Point Transmitter

Testo also offer the Testo 6740 pressure dew point transmitter which efficiently measures pressure dew point in compressed air or dry air/gas to help protect your compressed air system from moisture damage, therefore reducing maintenance costs.

The Testo 6740 offers; reliability, calculation of Ctpd, Ctd atmospheric and ppmv, pressure tight connection (up to 50 bar) and easy-to-use menu operation.
