S551 Portable Display and Data Logger The S551 is capable of sending measurement data and status information to a remote server through the Internet. This allows users to monitor the system remotely. The illustration below shows the principle setup. 268.5mm 168.5mm 374.5mm Applications M Modbus sensor M 3 A MPa ˚C MPa ˚C 1 ˚Ctd A ˚Ctd 4 2 Modbus sensor Field Devices Remote Office Location 4G Modem Local Ethernet LAN Remote Data Analysis Through the free SUTO S4A software recordings are down- loaded to the PC via USB, LAN or wirelessly using the LTE/4G Modem. The basic analysis can be done in S4A. For more sophisticated compressor analysis, the SUTO CAA software (incl. in S551) offers many advanced features such as: • Performance statistics of compressors (efficiency, air delivery, load/unload cycles) • Leakage analysis • Report generation • And more... Comparisons with baseline measurements from last year or last month help to identify system changes. Data Analysis Data Logging 1 2 16 S401 Flow Meter � with Modbus/RTU S220 Dew Point Transmitter with Modbus/RTU S415 Compact Flow Meter with Modbus/RTU RS-485 � Splitter RS-485 � Splitter RS-485 � Splitter The S551 Portable Display and Data Logger is the perfect tool for compressed air service engineers as well as compressed air experts. Due to it’s compact design and the integrated battery, on-site measurements are carried out most efficient user friendly. From simple dew point spot check up to identifying insufficient compressor systems, the S551 is the tool to make these measurements. S4A CAA 3/7
