Temperature Classification
Temperature class is a function of fluid temperature used in the meter and ambient temperature.
For hot fluids, 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
specification 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 specific to model number’s:
