Remote airflow monitoring and system automation control can now be achieved by using 4 mA to 20 mA output signals. ROTRON® 4 mA to 20 mA analogue output is proportional to system flow rates and can be used with PLC controlled operations to monitor system performance. Those same outputs provide digital displays for direct readings in SCFM when paired with the LCD Digital Readout option. Combined with variable frequency drives you can achieve an automated system capable of adjusting blower performance to meet changing system demands.• 4 mA to 20 mA signal output control signals provide flow rate monitoring capabilities from remote locations,• NEMA 1R-raintight enclosure protects the integrated DC power supply and rugged differential pressure transducer,• Suitable for remote mounting up to 10 form flow meter,• Weight: 3 lb,• Signal output: 4 mA to 20 mA, DC,• Hi\/Lo pressure fittings feature Snaplock action to unsure trouble-free connections,• System includes standard flowmeter for on-site readings and troubleshooting,• Operating temperature: 0°F to 150°FMedia Monitored = AirDevice Type = Flow IndicatorMinimum Flow Rate = 13 SCFMMaximum Flow Rate = 60 SCFMConnection Type = Snap-LockMaximum Pressure = 30psiMaterial = AluminiumMaximum Media Temperature = +60°CMinimum Operating Temperature = -18°CMaximum Operating Temperature = +66°C
