Airius wireless vibration sensors

The wireless Airius® sensor is a battery-powered vibration sensor ideal for remote condition monitoring of standard production equipment such as pumps and fans.

Providing warning of vibration-related problems as well as gear and bearing faults, Airius is ideal for remote condition monitoring of standard production equipment. Remote or inaccessible machines and equipment placed in hostile or risky environments are other suitable targets. With a compact and robust design, rated IP69, and an energy-saving WiFi communication protocol, Airius provides years of trouble-free use and stable monitoring. For maximum battery life, the sensors use a field-replaceable lithium-thionyl battery, which lasts for four years at four measurements per day.

The Airius sensors do not require any supplementary equipment besides WiFi routers. With the shortest response times in the segment, installation and commissioning are straightforward and fast.



The careful design and optimal choice of battery technology ensure years of trouble-free use and stable monitoring. In idle state, sensor power consumption is extremely low.


Using the well-established and stable WiFi data transfer technology, the wireless sensor is an easy-to-implement solution that works well within existing IT environments.


Start small with the cloud-based application Condmaster.NET and then expand with the sophisticated analysis and diagnostic software Condmaster Ruby.


Versions for potentially explosive environments will be released in the fall of 2019.

Airius is a MEMS type sensor with digital output, measuring triaxial vibration and temperature. The sensor comes in two versions; one measuring in the 10-1000 Hz frequency range, the other between 2-1000 Hz and 10-5000 Hz with envelope measurement capabilities. Airius supports several different vibration measurement assignments per sensor, with a user-defined number of time-based daily measurements. The signal processing algorithms and calculation routines used are the same as in the high-end Intellinova® online system and the sophisticated portable Leonova® Diamond and Leonova® Emerald instruments.

The SPM Connect app is used to configure the necessary communication parameters. It is easy to start small with the new cloud-based application Condmaster®.NET (hosted in SPM Cloud), providing easy access to measurement data through a user-friendly graphical interface, then expand with the sophisticated analysis and diagnostic software Condmaster® Ruby.
