The 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.

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.
