ABB expands non-invasive sensing portfolio to advance simpler and safer temperature measurement  

The new solutions are designed to address distinct application needs in oil and gas, chemicals, power, and marine where safety and accuracy are paramount. The solutions help operators maintain process control, reduce unplanned interventions, and meet site and regulatory requirements.  

NINVA clamps directly onto the outside of the pipe, giving plant operators accurate process temperature readings without the need to cut, weld or maintain traditional invasive thermowells. Using the surface temperature of piping to infer temperature, NINVA provides the same level of accuracy and performance of invasive measurement devices without the inconvenience of installing and maintaining them.  

With reduced design and engineering costs, and decreased material, inspection, and installation costs compared to thermowells, NINVA presents a more cost-effective measurement solution. With NINVA, customers can expect up to 75% reduction in workload and capital expenditure costs.  

"With the launch of the original NINVA, ABB pioneered a step-change in process temperature measurement," said Jacques Mulbert, president of ABB's Measurement and Analytics division. "With an ever-growing need for sensing, industrial operators see the value of not having to stop the process or cut into piping to get the insights they need." 

• NINVA Integrated is designed for use in the chemicals and oil and gas industries. It works with metal piping DN15 – DN2500 (1/2” –  100") and is ideal for brownfield upgrades where shutdowns and hot work are costly.   

• NINVA Remote is engineered for high-temperature and hard-to-access areas in power and utilities, especially steam and high‑temperature gas environments (400°C+). It withstands high vibrations of up to 2g. It pairs with ABB’s TTF300‑N field‑mount transmitter for flexible mounting and remote display, while maintaining robust temperature monitoring in harsh conditions.  

• Marine certified, NINVA Compact is designed for demanding machine environments where space is limited but reliable temperature indication is required. It has high vibration capability of up to 4g and works with small piping DN15+, skid systems, and mobile assets.  

In 2024, NINVA became the first SIL2-certified non-invasive temperature transmitter, making it the safest non-invasive temperature measurement sensor on the market.
