42/10-55 XU Temperature Sensor TSHD (SensyTemp Exd) GB3
Groups
The type examination PTB 99 ATEX 1144 was executed for potentially explosive atmospheres
of group IIC according to EN 50014:1997, EN 50018:1994, EN 50284:1997, and EN 1127-
1:1997.
Temperature class
The devices are normally marked with temperature class T6. Higher operating temperatures
are possible in case of potentially explosive atmospheres permissible for temperature class
T5 or T4. Operating temperature ranges are defined in section 2.3.
