Description

Resistance thermometers of these series are used as universal thermometers for the measurement of liquid and gaseous media in the range -50 ... +250 °C [-58 ... +482 °F]. The instruments are intrinsically safe and suitable for use in hazardous areas.

They can be used for pressures up to 140 bar [2,030 psi] with 3 mm [0.12 in] sensor diameters and up to 270 bar [3,916 psi] with 6 mm [0.24 in] sensor diameters, depending on the instrument version. All electrical components are protected against humidity (IP67 or IP69K) and designed to withstand vibration (20 g, depending on instrument version).

The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the WIKAsoft-TT PC configuration software. Measuring range, damping, error signalling per NAMUR NE 043 and TAG no. can be adjusted.

for further approvals, see page 8
