Non-invasive temperature sensor NINVA™ TSP341-N
NINVA™ stands as the innovative non-invasive temperature sensor, which is a simpler and safer way of measuring your process temperature without the need to shut down, drill a hole, or install a thermowell.
With its innovative double-sensor architecture and specially developed calculation algorithm, it greatly enhances your safety and reduces your installation costs without sacrificing the quality of your measurement.
Our solution is the technology proven by hundreds of global customers.
By consistently improving our non-invasive temperature monitoring solution, we have expanded its capabilities to tackle a wider range of measurement challenges faced by plants from the chemical and oil & gas sectors.
Overview
The NINVA TSP341-N non-invasive temperature sensor includes a transmitter based on TTH300. Integrated new algorithms enable the high precise temperature calculation. Output via 4 to 20 mA and HART protocol. Accuracy and response time are in the range of temperature measurements with thermowell. Learn more by reading the white paper.
The temperature sensor has global approvals for explosion protection up to zone 0. The non-invasive temperature sensor belongs to ABB’s product family SensyTemp TSP. It is listed in the related type examination certificates for explosion protection as SensyTemp TSP341-N.
Don’t wait for the next shutdown to get your temperature measurement. Contact us today to see if the non-invasive temperature sensor can meet your requirements. Our sales team have evaluation algorithms to tell you whether this sensor could help get the performance you need, faster, safer and without having to stop your process.
