Temperature Classication
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 (295-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
specication sheets and product family manuals are also available for viewing or downloading.
Electrical Requirements
The device must be powered with a Class 2 power supply. Electrical loads are specic to model number’s:
