Footnotes (without in-table superscripts):
When operating in hazardous areas, observe restrictions according to certificate. See CLS300 pressure/temperature curves.
Thermal isolator must be used if process temperature exceeds 85 °C.
Pressure rating of process seal is temperature dependent. See CLS300 pressure/temperature curves.
Intrinsically safe operation requires appropriate barrier or power supply
