IMI introduces Neon Sonic sensor
15/04/2026
MI plc has expanded its Neon portfolio with the introduction of the Neon Sonic, a new wireless sensor that combines acoustic and temperature measurement to support continuous monitoring of steam traps and pressure and safety relief valves. The launch comes as steam-dependent industries worldwide face persistent challenges related to condensation losses and steam trap malfunctions.
Enabled by long-range wide-area network (LoRaWAN) connectivity, the Neon Sonic captures sound frequencies ranging from 15 kHz to 80 kHz, alongside temperature readings from –40°C to 450°C. This dual capability enables operators to assess whether steam traps are functioning correctly or experiencing issues such as leakage or blockage.
Certified for the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx) and Atmosphères Explosibles (ATEX) Zone 0 environments, the sensor is approved for use in hazardous areas where explosive atmospheres may be present.
Designed for long-term deployment, the sensor offers a battery life of up to seven years, significantly reducing the need for routine manual inspections. Its wireless, self-powered design makes it well suited for retrofit applications, as it can be installed without external power sources or alterations to existing plant equipment.
Steam trap failures remain a widespread issue across power generation facilities, refineries and process industries, often resulting in the loss of 15% to 20% of steam energy. These inefficiencies contribute to higher operating costs and increased fugitive emissions, while also accelerating equipment wear caused by wet steam accumulation. Reliable monitoring helps plants minimise unexpected shutdowns, schedule maintenance more effectively and avoid the high costs associated with unplanned outages.
In addition to operational and environmental concerns, faulty steam traps pose safety risks to personnel. Manual inspection methods, still common in many facilities, expose workers to hazardous conditions and deliver infrequent, less precise data. Automated acoustic monitoring offers a safer and more accurate alternative, improving visibility into equipment performance.
Neon Sonic complements IMI’s existing Neon solutions, including the Neon Vibration Sensor, Neon Pressure Sensor and Neon Temperature Transmitter, which are already deployed across a wide range of energy and industrial applications worldwide.
Commenting on the launch, Nadine Nerrwerth, Business Development and Commercial Director at IMI, said that steam trap failures have a direct impact on both plant efficiency and environmental performance. She noted that Neon Sonic provides plant teams with the insights needed to address these challenges while improving operational safety and sustainability.
