1 The analog transmitter is certified for applications with temperature classes T6...T4. If the ambient temperature for this device is not
more than the maximum limit for temperature classes T6...T4, the analog transmitter can be attached to a measuring chamber for
applications with temperature classes T6...T1.
INFORMATION!

The analog transmitter and limit switches are certified for applications with temperature classes
T6...T4. If the ambient temperature for these devices is not more than the maximum limit for
temperature classes T6...T4, the analog transmitter and limit switches can be attached to a
measuring chamber for applications with temperature classes T6...T1.
Use the lowest value in the tables in this section to get the maximum temperature limit for the
measuring chamber with analog transmitter and limit switch options.
