S330 / S331 from SUTO is a very powerful yet cost effective new data logger and display solution. The high resolution 5” graphic display allows an easy operation where details are much sharper shown compared to many of the smaller low resolution displays. The USB port works as a slave in combination with a PC, but also as a master when recorded data has to be transferred to a USB stick. Its versatility in regards of sensor inputs makes it a perfect solution for most measurement tasks.


  • Measures, displays and records all relevant parameter of a compressed air systems: flow, dew point, pressure, temperature, power consumption, compressor status, and so on.
  • High resolution 5” colour touch screen interface
  • All SUTO sensors are connectable as well as third sensors are connectable
  • 16 x Modbus inputs (58 standard or optional 108 Channels)2 x SDI inputs (20 channels), 2 x SDI inputs (20 channels), 2 x Analog and pulse input (4 channels), Plus 10 virtual channels for calculations like kW/m³/min orDifferential pressure
  • 2 wall casings available (4 or 7 cable glands)
  • USB interface for data transfer to data stick or PC
  • RS-485 (Modbus/RTU, SUTO-Bus) and Ethernet (Modbus/TCP, SUTO-Bus) interface to factory automation system
  • 10 W sensor power supply (24 VDC)
  • Data logger (S331 only): 100 million values
  • Alarm monitoring with 2 relay outputs
  • Integrated web server for remote monitoring
  • Quick set up
  • Various options for system extension
  • Monitor compressor run time

The S320 compressed air meter provides a cost effective display solution for industrial applications. The display has an input for SUTO flow meters and dew point sensors. It also comes with an analog sensor input (0… 20 mA, 0… 10 V).


  • Attractive price
  • 1 input for SUTO flow/dew point sensor
  • 1 input for analog sensors (0 … 20 mA, 0 … 10 V)
  • Communication Interfaces: USB port
  • Sensor outputs: 2 alarm relay outputs

The S551 Portable Data Logger for compressed air efficiency monitoring is the ideal data logger for energy analysis (ISO 50001) and air audits (ISO 11011) on site. It comes with a high resolution 5” color touch screen interface, making the operation as simple as possible. SUTO intelligent sensors are detected automatically on power-up. With a few settings, the data logger is ready for operations with virtually unlimited memory size.


  • Just connect the sensor and start the recording, no configuration and programming required
  • Easy operation through color-touch display
  • Integrated web server for remote monitoring
  • Connectable sensors for all required measurement tasks
  • Up to 24 inputs through extension boxes and Modbus
  • Several loggers can be combined: no need to have long cables from the sensor to the logger
  • Third party sensors can be easily connected
  • S551 logs data on site
  • Data is analyzed in the office
  • Cost-effective solution
  • Full software package includes: S4A for basic analyzes, CAA for compressed air audit analyzes
  • Power glitches and cuts won’t affect performance: battery backup power
