These thermocouples are designed for solid body temperature measurement, for example, bearing blocks. Sensors can be of explosion protection type 0ExiaIICT6 X according to GOST 30852.10-2002. For further de-tails see "Alternative designs & Ordering information" below. If required, thermocouples with 4-20 mА DC signal and/or digital signal via HART, PROFIBUS-PA, FOUNDATION Fieldbus protocol, can be equipped with remote measuring transmitters
