344 Thermoelectric temperature sensor Ex d (Ex t, Ex i) with thermowell ČSN without converter or with converter
- For exact remote measurement of temperature of steady and running liquids (gases and fluids), for which the properties of the thermowell of the sensor are suitable; measurement may be realized to the temperature max. 600°C and nominal pressure PN 160
- For environment with explosive gaseous atmosphere according to EN 60079-10-1 and explosive atmospheres with combustible dust according to EN 60079-10-2
- Thermowell of the sensor may be installed in Zone 0(20), Zone 1(21) or Zone 2(22)
- Other parts of the sensor (screw union, adapter, connecting head) may be located in Zone 1(21) or Zone 2(22)
- In case of application of the converter Ex ia or connection to Ex ia circuit according to EN 60079-25, the sensor may be used in Zone 0 (20), 1 (21) and 2 (22) - In a set with control or diagnostic systems for process monitoring
- In design with converter to convert signal of the thermoelectric sensor to unified output signal 4 to 20 mA or digital signal (converter with HART protocol)
- In design with display to display the value of the measured value immediately
- For the environment, where mechanical resistance is required pursuant to EN 60068-2-6 (class AH2) and seismic capability of the electrical equipment of the safety system of the nuclear power stations pursuant to IEC 980 (MVZ level SL-2)
- The sensors with converter are rated products pursuant to the Directive 2014/30/EU of the European Parliament and the Council and EU Declaration of Conformity EU-234000 is issued for them.
