CS74 Intrinsically Safe Temperature Transmitter

CSA Class 1, Division 1, Groups C and D, T3
Class 1 Zone 1 AEx ia IIB T3 Gb

Core Sensors offers the CS74 Intrinsically Safe temperature transmitter, designed for use in hazardous locations with an approved barrier (see page 3 of datasheet for entity parameters). Features include a 316L SS probe and thread area and a stainless steel housing, making it compatible with a wide range of process liquids and gasses for harsh applications. Configurable temperature ranges from -40 to +200°C are available with various probe lengths. A wide variety of standard electrical connections are available with 4-20mA or various voltage output signals.
