In the process of brewing liquor, the fermentation in the cellar is very important. When entering the cellar, the temperature and humidity of the cellar will affect the taste of the liquor. Generally speaking, the fermentation time in the cellar is about 1 month, but the specific fermentation time depends on the actual situation of…
First, let’s take a look at their definitions. Two-wire system: two wires transmit both power and signal, that is, the load and power output of the sensor are connected in series. The power is introduced from the outside and connected in series with the load to drive the load. Three-wire system: A three-wire sensor is…
