Temperature Classication
Temperature class is a function of uid temperature used in the meter and ambient temperature. For hot uids, meter
must be insulated and transmitter must be left exposed. All transmitters are rated to operate within the BLUE region,
but only the remote sender unit variants (EX29x-x5x-xxx) can operate up to the maximum temperatures shown in the
chart. Consult factory for installation details when operating near temperature limits.
Temperature class chart for all explosion proof variants:
Note: Consult factory to determine the functional temperature limit of your transmitter variant. Temperature class
ratings do not correspond with the continuous duty area for the electronics within the transmitter. A complete
description of your transmitter may be found on the Max Machinery web site (www.maxmachinery.com). Individual
specication sheets and product family manuals are also available for viewing or downloading.
