304

These sensors are designed for measurement of solid surface temperature, liquid and gaseous non-corrosive media temperature, and also temperature of corrosive media that do not damage thermowell material.
Sensors can be of explosion protection type 0ExiaIICT6 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 transmitters .
