Airius wireless vibration sensors

The wireless Airius® sensor is a vibration sensor ideal for remote condition monitoring of standard production equipment.

Providing warning of vibration-related problems as well as gear and bearing faults, Airius is ideal for remote condition monitoring of standard production equipment such as pumps and fans. Remote or inaccessible machines and equipment placed in hostile or risky environments are other suitable targets.

Vibration data is transmitted through well-established WiFi technology or over cellular networks using secure LTE-M radio technology. 

With a compact and robust design, rated IP69, Airius provides years of trouble-free use and stable monitoring. The battery-powered version uses a field-replaceable lithium-thionyl battery that lasts for four years at four measurements per day. The sensor is also offered in a version with an external power supply.

Besides a router for WiFi communication, the Airius sensors do not require any supplementary equipment. With the shortest response times in the segment, installation and commissioning are straightforward and fast.
Trouble-free use


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.
Easy integration


Using the well-established and stable Wi-Fi data transfer technology, the wireless sensor is an easy-to-implement solution that works well within existing IT environments.
A smart way to start


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

Airius II LTE-M

– reliable, secure, and future-proof IoT solution

Airius with data transmission via the mobile network is an ideal monitoring solution for equipment not covered by the plant's local area network or WiFi, such as rooftop fans, pumps, and motors in water treatment facilities, pumping stations, or hydropower sites.

The cellular connectivity standard LTE-M, developed specifically for IoT, offers superior coverage and penetration as well as solid, built-in security in existing mobile networks. Needing no extra hardware other than the sensor itself, getting started with the Airius II LTE-M is easy and fast!


For vibration monitoring of industrial machines in areas with potentially explosive atmosphere, an Ex version of Airius is available.

Minor investment – major impact

Much more efficient than manual inspections, an Airius remote monitoring solution is a cost-effective tool to help facility managers and maintenance supervisors make confident decisions on maintenance and repairs, reduce the risk of failures, and cut operating costs.

Utilizing well-established measurement, communication, and visualization technologies, this robust solution is ideal for facilities management, pumping stations, solar farms, water treatment, warehouses, and many other industrial environments.

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.
