These sensors are designed for solid body temperature measurement, for example, bearing temperature; and temperature measurement of liquid and gaseous media that do not destruct thermowell material, for example, natural gas. Sensors can be of explosion protection type 0ExiallCT6 X according to GOST 30852.10-2002. For further details 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.
