ABB Enhances Non-Intrusive Temperature Measurement for Critical Industries
ABB has expanded its NINVA™ non-intrusive temperature measurement portfolio with three new product variants: NINVA™ Integral, NINVA™ Split, and NINVA™ Compact. The expanded range is designed to provide safer, simpler, and more cost-efficient temperature measurement across demanding industrial applications.
Targeted industries include oil and gas, chemical processing, power generation, and marine operations, where operational safety, measurement accuracy, and reduced maintenance intervention are critical requirements.
Clamp-On Temperature Measurement Without Process Interruption
The NINVA™ series enables temperature measurement directly from the external surface of pipelines, eliminating the need for intrusive installation methods such as pipe cutting, welding, or process shutdowns.
By clamping onto the outside of the pipe, NINVA devices estimate internal process temperature through advanced thermal modeling techniques, delivering performance comparable to traditional thermowells while significantly improving installation safety and efficiency.
This approach helps industries reduce both engineering complexity and lifecycle maintenance costs, while improving operational uptime.
Key Benefits of ABB NINVA™ Technology
No pipe penetration required
No hot work permits or process shutdowns during installation
Reduced installation and maintenance costs
Improved operational safety
High accuracy comparable to intrusive temperature sensors
Suitable for retrofit and upgrade projects
According to ABB, customers can achieve up to 75% reduction in engineering and capital expenditure compared to traditional thermowell-based solutions.
Product Line Overview
NINVA™ Integral
Designed primarily for oil and gas and chemical industries, the Integral version supports metal pipelines from DN15 to DN2500 (½ inch to 100 inches). It is optimized for plant retrofits where minimizing shutdown time and avoiding hot work are essential.
NINVA™ Split
Engineered for power generation and utility applications, the Split version is suitable for high-temperature environments exceeding 400°C, such as steam and high-temperature gas lines. It can withstand up to 2g vibration and is typically used with ABB’s TTF300 N field transmitter for flexible installation and remote monitoring in harsh environments.
NINVA™ Compact
The Compact version is certified for marine applications and confined installations where space is limited. It supports DN15 and above small-bore pipelines, skid systems, and mobile equipment. With resistance up to 4g vibration, it is ideal for harsh mechanical environments and has received classification society approvals for marine use.
Safety and Certification Milestone
In 2024, NINVA became the first non-intrusive temperature sensor to achieve SIL2 certification, reinforcing its position as a safety-focused solution for critical industrial applications where reliability and functional safety are essential.
Industry Impact
With increasing demand for digitalization, predictive maintenance, and safer plant operations, non-intrusive sensing technologies like NINVA are gaining strong adoption. ABB’s expanded portfolio supports industrial operators in:
Improving process visibility without operational disruption
Enhancing safety compliance in hazardous environments
Reducing downtime during upgrades and maintenance
Supporting ESG-driven efficiency improvements
Conclusion
ABB’s expansion of the NINVA™ portfolio represents a significant step forward in industrial temperature measurement technology. By eliminating the need for invasive installation methods, the solution offers a safer, more cost-effective, and highly reliable alternative for critical process industries worldwide.
