Airius wireless vibration sensor

The Airius® wireless vibration sensor is 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 Wi-Fi 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 for the Wi-Fi version and two measurements per day for the LTE-M version. The wireless vibration sensor is also offered in a version with an external power supply.

Best-in-class overall value

The Airius wireless vibration sensors are a reliable and high-quality remote monitoring solution with a very competitive lifecycle cost.

Without incurring high costs for cabling or gateways and with the possibility to replace batteries on-site, Airius offers optimal vibration monitoring efficiency with low environmental impact. Easy installation and configuration procedures make for hassle-free deployment and quick return on investment.

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.


Airius is an industrial-grade solution with secure IoT connectivity. Whether opting for local or cloud-based data storage, Airius users are always in control of their data.


With its robust design and the possibility to replace batteries on-site – rather than replacing the sensor itself – Airius will deliver performance and sustainability for many years.

Airius II Wi-Fi – straightforward installation and effortless setup

Using the well-established and stable Wi-Fi data transfer technology, Airius works well within existing IT environments. Besides Wi-Fi routers, the Airius wireless vibration sensors do not require any supplementary equipment. With the shortest response times in the segment, installation and commissioning are straightforward and fast.

The SPM Connect app, downloadable for mobile devices, is used to configure the necessary communication parameters. A cloud-based web app provides easy access to measurement data on mobile phones, tablets, and laptops through a user-friendly graphical interface.

Airius II LTE-M – reliable, secure, and future-proof IoT solution

Airius wireless vibration sensor with data transmission via the mobile network is an ideal monitoring solution for equipment not covered by the plant's local area network or Wi-Fi, 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.

Features – wireless vibration sensor

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 2-5000 Hz with envelope measurement capabilities. Airius supports several different vibration measuring 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.
