† Process temperatures above 125 °C (257 °F) require a reduction in the maximum ambient temperature as follows:
Process Temperature
150 °C (302 °F)
140 °C (284 °F)
125 °C (257 °F)
†† Process temperatures above 65 °C (149 °F) require a 1:1 reduction in maximum ambient temperature.
NOTE: For transmitters with local meter option see Table A-2.
NOTE: Transmitters with other fill fluids (CTFE, Neobee, Etc.) have different Operating Temperature Limits. For
more specific information, refer to the appropriate Specification and Model Selection Guide or transmitter nameplate

Table 5 lists the operating temperature limits for the various types of
transmitters with silicone fill fluids. See transmitter specifications for
temperature limits of transmitter with alternative fill fluids.
