252 Resistance temperature sensor Ex d (Ex t, Ex i) with metal or ceramic protective tube without converter or with converter
- For remote measurement of temperature of gases, for which the properties of the material of the protective tube are suitable (e.g. in furnaces)
- 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 resistance 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
- 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
