Classic temperature measurement in process technology is carried out by directly inserting a temperature sensor with a thermowell into a measuring medium, which is usually located in a vessel or piping. Last fall, ABB introduced 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 temperature without the need to shut down, drill a hole, or install a thermowell.
Shown for the first time in North America at ABB Customer World, 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, and it features proven components and the common ABB look and feel with text display making commissioning and handling easy.
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 sensors that need to be removed and inserted into the process, even more so when it is a volatile or caustic product 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 CAPEX.
NiTemp’s use with liquid media with low viscosity, high thermal conductivity and/or turbulent flow in metal pipes is particularly advantageous. Applications range from processes with hazardous media, processes with special hygiene requirements and/or stringent cleaning requirements, to high-pressure processes with high bending loads or use with 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 to be launched in North America later this year.
