IMI TWTG
NEON QT Valve Sensor
Valve position sensor for industrial quarter-turn valves, designed for rapid, non-intrusive installation and near realtime monitoring of manual valve activity.
Universal bracket fits any quarter-turn valve, enabling fast, installation in under two minutes with no process interruption required.
Secure LoRaWAN wireless connectivity delivers reliable, near real time valve status data from even the most challenging industrial environments.
Built for harsh conditions with IP65 protection, ATEX/IECEx Zone 1 certification, and a battery life of up to 5 years, ensuring long-term, low-maintenance operation.
Features
Having reliable information available is the essence of good decision making to ensure safety in working environments, especially in industrial sites.
As a result, businesses will run more efficiently and operations will be streamlined. IMI's Industrial IoT-connected valve sensors provide this insight.
Unlock efficiency and safety with the NEON Valve Sensor
Our NEON Valve Sensors are designed to communicate whether a valve is in the open or closed position. This capability reduces the likelihood of false positives while providing you with outstanding measurement accuracy.
The NEON QT Valve Sensor ensures universal compatibility with any sized quarter-turn valve available on the market.
Innovative design for optimal performance
The NEON QT Valve Sensor is an industrial-grade device designed to withstand harsh and hazardous environments. It has been rigorously tested and certified to operate safely in explosive atmospheres (ATEX zone 1 / IECEx class 1). With its ability to function in temperature ranges from -40° to +80° Celsius, the valve sensor ensures reliable performance in valve position monitoring even under the most challenging conditions. Its redesigned universal bracket, swift installation, and minimal maintenance requirements underscore IMI’s commitment to continuous innovation, adaptability, and user convenience.

With universal compatibility and multiple orientation versatility, the new NEON sensor assembly can be intuitively fitted to any valve head on the market in under two minutes.
Proven technological functionality
The all-new bracket has been innovatively engineered to ensure both safety and practicality. In fact, it serves not only as a mount but as a functional component of the sensor mechanism. As a result, the NEON QT Valve Sensor is positioned directly at the center of the valve head, away from the handle, which prevents accidental contact with an engineer’s hands. This feature helps avoid potential miscalibration or even accidents.

All NEON sensors can be installed on new or existing equipment based on your digitisation strategy. By continually increasing the number of digital measuring points in an industrial facility, engineers can gain better insight into the running and interdependencies of their operations.
Reliability is the first thing to consider when providing insight based on new technologies. Therefore, our Valve Sensors have been specifically designed to only communicate the essential: closed or open. This allows our customers to reduce false positives immensely and be certain of the measurements the sensor delivers.
The sensors communicate via a privately hosted LoRaWAN network, with gateways tailor made for the same industrial conditions and requirements of the Valve Sensor (globally). IMI can install this network and it has been designed to scale up in numbers and for other I-IoT solutions in the future. Furthermore, they can be integrated with DCS / SCADA systems to ensure operational excellence.
