Using Non-Invasive Sensors for Temperature Measurement

The non-invasive sensor represents a new era of temperature measurement. The device offers a safer and simpler way of measuring process temperature without the need to drill a hole, install a thermowell, or shut down.

The non-invasive temperature sensor, with its novel double sensor architecture and uniquely designed calculation algorithm, not only improves the safety aspects dramatically but also reduces installation costs without affecting the quality of the measurement. Currently, the NiTemp is available only in the European market.


The non-invasive temperature sensor features a transmitter based on TTH300. Moreover, built-in new algorithms enable highly precise measurement of temperature. The output is through 4 to 20 mA and HART protocol. Response time and accuracy are in the range of temperature measurements with thermowell.

The non-invasive temperature sensor has international approvals for explosion protection up to zone 0. It belongs to ABB’s product range — SensyTemp TSP. Furthermore, the NiTemp is listed in the related type-examination certificates for explosion protection as SensyTemp TSP341-N.

Users should not wait for the next shutdown to get their temperature measurement. They can get in touch with ABB to see whether the non-invasive temperature sensor meets their application needs. ABB’s sales team has evaluation algorithms to tell users whether the non-invasive instrument could help get the performance they need, safer, faster, and without having to halt their processes.
