243 Resistance temperature sensor Ex d (Ex t, Ex i) to 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 selected by the customer are suitable; measurement may be realized up to temperature (max. 450°C) and pressure determined by thermowell resistance
- For environment with explosive gaseous atmosphere according to EN 60079-10-1 and explosive atmospheres with combustible dust according to EN 60079-10-2
- Sensor may be installed into the thermowell located in zone 0 (20), zone 1 (21) or zone 2 (22), the thermowell for zone 0 shall comply with the requirements of EN 60079-26 ed. 2 (refer to figure 2)
- Other parts of the sensor (screw joint, adapter, connecting head) may be located in zone 1 (21) or zone 2 (22)
- Sensor without converter or converter with Ex ia version, when connected to Ex ia circuit according to EN 60079-25 in zone 0, 1, 2, 20, 21 and 22 - In a set with control or diagnostic systems for process monitoring
- In design with converter for transfer of resistance sensor signal 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
- 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)
- special design for cryogenic environment with medium temperature up to -196 °C
- The sensors with converter are rated products pursuant to the Directive 2014/34/EU, 2014/30/EU of the European Parliament and the Council and EU Declaration of Conformity EU -243000 is issued for them.
- For use temperature sensors as separate assemblies of the heat meter on placing on the market.
- The sensors are rated products pursuant to the Directive 2014/32 EU of the European Parliament and the Council and EU Declaration of Conformity EU-MID-243000-EN is issued for them.
- Using sensors within the meaning of Directive 2014/32 EU of the European Parliament and the Council. (MID) as part of the customers measurement kits, for which the conformity of the assemblies as a whole must be assessed when placed on the market with all the features required by this directive:
- sensor without transmitter in 1xPt100 /../ 4 connection can be used by the customer on the basis of an evaluation certificate in its measuring sets in the sense of Directive 2014/32 EU of the European Parliament and the Council
