244 Resistance 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 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 EN IEC/IEEE 60980-344 (SSE/S2)
- special design for cryogenic environment with medium temperature up to -269 °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 -244000 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-244000-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
