Page 7: Flammable Products
An area in which an explosive atmosphere as a result of the mixture of flammable substances in the form of gas, steam or mist with air is not expected to occur under normal operation. If, however, such an atmosphere does occur it only lasts for a brief period of time. 08/2017 - A5E42667474-AA EN www.siemens.com/flow... -

The classification is outlined in the following tables. The tables take into account the following parameters: • Ambient temperature T • Product temperature T • Nominal size DN • Heat resistance of the connecting cable www.siemens.com/flow 08/2017 - A5E42667474-AA EN... - Page 9 Insulation must be limited to the piping. Unobstructed ventilation of the signal converter • must be ensured. The permitted ambient temperature range is indicated on the nameplate; depending on the device version it is T = -40...+65°C / -40...+149°F. The minimum product temperature is -40°C / -40°F. 08/2017 - A5E42667474-AA EN www.siemens.com/flow...
