SIL2 NINVA TSP341-N Non-Invasive Temperature Sensor Removes Need for Thermowell Testing
ABB has launched an enhanced version of its NINVA TSP341-N non-invasive temperature sensor, delivering safer and simpler temperature measurements for applications in the chemical, oil, and gas industries.
The SIL2-certified non-invasive temperature transmitter uses the surface temperature of the piping to infer the process temperature. It provides the same level of accuracy and performance as an invasive measurement device without the risks and lifecycle costs associated with specification, installation, and maintenance.
NINVA TSP341-N is built on ABB's TTH300 temperature transmitter and delivers new features based on customer feedback. Features include a remote mount configuration, improved resistance to vibration, optional configurations for applications up to 1,022°F (550°C), and simpler calibration and maintenance through extractable measuring insets with independent sensor calibration and trimming.
Clamp collars for pipe diameters of 1.5 to 98 in. (40 to 2,500 mm) and special designs for diameters below 1.5 in. (40 mm) also avoid the need for complex thermowell designs for smaller pipes without sacrificing accuracy or performance.
“Customers are really driving the market for non-invasive process measurement. With an ever-growing need for sensing, global players in the chemical and oil & gas industries see the value of not having to stop the process or cut into piping to get more insights. By turning a piece of process piping into a temperature measurement point, NINVA provides a simpler and safer way for plant operators to measure process temperature without compromising on performance—no shutdown, no holes, with dramatically simplified engineering.” — Dr. Guruprasad Sosale, ABB Measurement & Analytics.
With its clamp-on approach, the mounting configuration eliminates the risks, inspection, and administrative costs of maintaining welded mounting connections. By removing the need to perforate the pipe wall, NINVA avoids potential leakage and reduces trouble points during plant commissioning.
