SPM Instrument advances condition monitoring platform with new technologies
Aaron Blutstein 16 March 2026 
SPM Instrument has introduced updated versions of its DuoTech and Airius sensors, alongside Performance+, a new software add-on for the Intellinova Parallel EN online condition monitoring system. The developments expand the capabilities of the company’s condition monitoring platform, covering wireless sensors, wired transducers and increased processing capacity within the online monitoring system.
According to SPM Instrument, the updates are intended to improve overall system performance while maintaining measurement precision and operational flexibility.
The new sensors and software enhancements are designed to support more advanced data processing and analysis within industrial reliability programmes, enabling users to monitor machine condition more effectively across a range of applications.
“These enhancements strengthen the entire SPM ecosystem,” said Johan Nilsson, R&D Manager at SPM Instrument. “From sensors to signal processing, we continue to develop the technologies that underpin our solutions, allowing users to maintain high levels of measurement accuracy and reliability.”
Airius III
The new Airius III expands the Airius range of wireless vibration sensors with a wake-up function that allows the sensor to respond instantly to vibration events between scheduled measurements, ensuring that important changes are captured even outside the normal measurement cycle. The feature is particularly valuable in applications where operating conditions change rapidly or loads occur intermittently. In crane applications, for example, vibration measurements are most meaningful when the crane is under load. Because load events occur unpredictably, the wake-up function ensures that relevant vibration data is captured when it matters most. Airius III also delivers improved measurement performance, including enhanced sensitivity for low-RPM machinery, lower noise levels, up to five times higher precision, a higher g-force rating, and a higher sampling rate. Operating across a 2–5,000 Hz frequency range, Airius III delivers the signal quality and reliability required for demanding industrial environments and provides even greater flexibility in wireless monitoring.
DuoTech II
The new DuoTech II accelerometer range further advances SPM’s combined shock pulse and vibration measurement technology. Building on a well-established design platform used in demanding industrial applications, the new generation introduces mechanical improvements that enhance measurement stability and reproducibility. The updated design increases mechanical robustness and ensures consistent measurement performance even in challenging operating environments. Engineered for greater flexibility, the DuoTech II family is available in multiple versions to support different application requirements. A new low-transverse-sensitivity version is especially well suited for high-precision applications such as rotor balancing. In addition to improved measurement performance, optimised production reduces the environmental footprint, supporting SPM’s sustainability initiatives in production and sourcing.
Performance+
Performance+ is a new software add-on for the Intellinova Parallel EN online system, available across all Condmaster editions. By optimising DSP utilisation, it increases measurement and processing capacity by 50 percent, enabling significantly more parallel measurements and faster data handling without adding to the system’s environmental impact. The enhanced processing capability allows the system to respond more quickly to events in demanding applications. This is particularly valuable for high-speed machinery, equipment with short measurement windows, or installations operating under non-continuous load conditions. Available for both new and existing Intellinova Parallel EN systems, Performance+ takes this powerhouse system, with its many uniquely powerful capabilities, supreme flexibility, and outstanding measurement performance, to new levels of efficiency.
Condmaster software support
DuoTech II and Performance+ require the 2026.3.0 revision of the Condmaster Ruby analysis and diagnostics software, while Airius III will be supported in a later revision. In addition to supporting DuoTech II and Performance+, the 2026.3.0 Condmaster revision also introduces significant improvements for managing large installations and commissioning large numbers of Airius sensors.
