Q&A with Defense Advancement: How Reventec Sensors Support Mission-Critical Performance in Defence Environments
Neville Meech, Managing Director of Reventec, recently spoke to the team at Defense Advancement to share insights into why the company’s solid-state liquid level sensors excel in harsh military environments, the wide range of platforms where they are already deployed, and the latest innovations being unveiled at DSEI 2025.
What makes Reventec’s solid-state liquid level sensors particularly suited for use in harsh military environments?
Our sensors are designed from the ground up to be resilient in the most demanding military environments. The key is our solid-state capacitive technology, which means there are no moving parts to wear out or fail due to high-frequency vibrations and shocks. This is a critical advantage over traditional float sensors. We also ensure our sensors are rigorously tested to meet military EMC standards, including MIL-STD-461G, DEF STAN 59-411, and RTCA DO-160G, which guarantees they won’t interfere with other sensitive onboard electronics and are resistant to external interference. Additionally, our sensors are fully sealed, offering ingress protection up to IP69K, making them impervious to dust, water, and other contaminants. This robust design ensures long-term reliability and minimal maintenance, which is vital for operational readiness.
In what types of military platforms, land, sea, or air, are your sensors currently deployed, and what advantages do they bring in those settings?
IU-020-03
Our sensors are deployed across a range of military platforms, including unmanned aerial vehicles (UAVs), ground vehicles, and small vessels. While we keep most of our customer information confidential, we can highlight our work with companies including Shield AI, Carbonix, and Alpha Unmanned Systems. In these settings, our sensors provide continuous, high-accuracy fluid level data, allowing operators to precisely monitor fuel consumption, extend mission duration, and perform predictive maintenance. For instance, in a UAV, knowing the exact fuel level helps maximize flight time and range, which is critical for intelligence, surveillance, and reconnaissance missions. For ground vehicles, it helps prevent unexpected breakdowns in the field by enabling proactive maintenance based on real-time fluid status.
What are some recent innovations or developments in your position sensing technologies that you’ll be showcasing at DSEI 2025?
At DSEI 2025, we’ll be highlighting our non-contact position sensing technologies, including a new dynamic live demonstration that will highlight an current application we are developing. In recent years, we’ve introduced a blade shaft position sensor that combines the accuracies and solid-state benefits of advanced Tunnelling Magneto-Resistive (TMR) technology but packaged as a drop-in replacement for potentiometers and legacy systems.
A major advantage of this technology is its ability to measure through non-ferrous materials, such as aluminium, which is incredibly useful for applications with sealed casings or where the sensor cannot be directly exposed to the component. This provides a highly durable and reliable solution for measuring everything from linear actuator position to rotary movements in harsh environments. We are continuously innovating to provide obsolescence protection for in-service assets, and this technology is a prime example of that commitment.
What key messages or capabilities is Reventec hoping to communicate to defence stakeholders at DSEI this year?
Our key messaging at DSEI this year revolves around the concept of “Defend for Longer”. This encapsulates our core capabilities: our sensors provide the critical, real-time vehicle health data that enables military platforms to extend their operational range and mission duration. By providing continuous and accurate data on fuel, oil, and coolant levels, as well as component position, our technology helps reduce vehicle downtime and supports predictive maintenance. This ensures that assets are always mission-ready, giving operators a tactical edge. We are focused on empowering defence stakeholders with the vehicle intelligence they need to optimise their operations.
What can visitors to your stand at DSEI 2025 expect to see, and how is Reventec positioning itself to meet future demands in defense sensor technologies?
Visitors to our stand can expect to see live demonstrations of our solid-state sensor technologies, showcasing their performance in real-world applications. We will have a wide variety of liquid level, position, and temperature sensors on display, including our latest product developments. Reventec is positioning itself to meet future demands by focusing on customisation and continuous innovation, which ideally places us to best serve existing vehicles requiring mid-life upgrades whilst delivering technology for new vehicle platform development. We understand that every defence platform is unique, which is why we offer highly configurable and bespoke sensor solutions. Our ability to develop custom sensors for specific spatial constraints and fluid types, combined with our commitment to meeting rigorous mil-spec standards, ensures we can provide reliable, next-generation sensing solutions for the evolving needs of the defence sector.
