ABB NINVA non-invasive temperature instruments

ABB has expanded its NINVA non-invasive temperature instrument range with the introduction of NINVA Integrated, NINVA Remote and NINVA Compact. The latest solutions are designed to address needs in oil and gas, chemicals, power and marine applications.

NINVA instruments clamp directly onto the outside of the pipe, giving plant operators 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, according to ABB.

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

NINVA Integrated is designed for use in the chemicals and oil and gas industries. It works with metal piping DN15–DN2500 and is suitable 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 (more than 400°C) and withstands high vibrations of up to 2g. It pairs with ABB’s TTF300‑N field‑mount transmitter for flexible mounting and remote display. 

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