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 09/2018 - A5E39673922-AB... - 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. 09/2018 - A5E39673922-AB www.siemens.com/flow...
