Non-invasive sensor eases temperature measurement

Mar 06, 2019

In the fall of 2018, ABB ushered in a new era in temperature measurement with the launch in Europe of NiTemp, a non-invasive temperature sensor that offers a simpler and safer way of measuring process temperatures.

Temperature measurement in the process industries is classically carried out by inserting a temperature sensor into a thermowell that intrudes into the pipe or vessel where the temperature is to be measured. But the NiTemp, being shown for the first time in North America at ABB Customer World this week in Houston, accurately measures temperature without the need to shut down, drill a hole, or install a thermowell.

The device is designed for surface measurement and eliminates the need for a thermowell, avoiding process intrusion altogether. This greatly increases safety in large part because high pressure can be dangerous when replacing a traditional sensor—even more so when a volatile or caustic product is being produced. There is also no need to shut down for installation and service, which means improved plant availability and up to 75% reduction in installed costs.

NiTemp features an innovative double sensor architecture and specially developed calculation algorithm that greatly enhance safety and reduce installation costs without sacrificing measurement quality. ABB developed NiTemp with direct testing and feedback from key customers in the oil and gas, chemical, and food and beverage industries. It features proven components and the common ABB look and feel, making commissioning and handling easy.

NiTemp’s use with liquid media with low viscosity, high thermal conductivity and/or turbulent flow in metal pipes is particularly advantageous. Other applications where the sensor’s non-intrusive nature is particularly compelling include processes with hazardous media, special hygiene requirements and/or stringent cleaning requirements, high-pressures with high bending loads and abrasive media.

NiTemp has global approvals for explosion protection up to zone 0, is suitable for different media and pipe diameters, and can be used in all areas of the process industries, utilities and municipalities. NiTemp is scheduled for launch in North America later this year.
