Will silicone oil in a capillary freeze at -20°C?

Will the silicone oil in the capillary of single-flange or double-flange types freeze at -20°C?
Silicone oil is a synthetic oil with a very low freezing point, generally below -50°C. Therefore, at -20°C, silicone oil in the capillary generally does not freeze, whether it is a single-flange or double-flange type. However, the specific freezing point depends on the exact model and viscosity of the silicone oil. .

For the standard EJA 118E transmitter, the operating temperature range is -40 to 60°C; for those with an LCD display, it is -30 to 60°C. There are also separate high-temperature resistant products. For details, please refer to the specifications provided by the respective manufacturer, which also include separate information regarding the operating temperature of the silicone oil.
