testo 6441, testo 6442, testo 6443, testo 6444 testo 6441, testo 6442, testo 6443, testo 6444 Measurement of norm volume flow In the Sensor positioned exactly In measurement stretch with defined Inner diameter and volume flow adjustment ensure highest accuracy Highest flexibility thanks to different signal outputs: - Pulse output - 2 switch outputs (parameterizable: consumption or volume flow-dependent, opener, closer, hysteresis, window) Built-in totalizer, even without additional analysis Operating menu with LED display Cleanable sensor testo 6441, testo 6442, testo 6443, testo 6444 The compressed air counters testo 6441 to testo 6444 are designed for the measurement, monitoring and recording of compressed air consumption, and therefore also for the determination of leakages In compressed air systems, consumption-based allocation of costs and the Implementation of peak load management. Using the compressed air counters testo 6441 to testo 6444, transparency of consumption is created for compressed air, similarly as flor the media current, water or gas, thus Increasing the motivation of those responsible for the process regarding cost reduction measures and energy savings. The compressed air counters testo 6441 to testo 6444 record norm volume flow according to the calorimetrie principle, which means the measurement procedure is Independent of the process pressure and does not cause a permanent pressure drop. While the the thermal, glass-coated ceramic sensor offers a high level of robustness and fast response times, the integrated Inflow and outflow pipes ensure optimum accuracy. • Leakage detection, compressed air consumption Consumption cost allocation Peakload management • Mln./max. monitoring • Control of consumption-dependent maintenance • Automatic, exact compressed air dosage
