Bimetallic thermometer used in brewing equipment1

In the process of wine making, temperature played a crucial role, once the temperature control is not good, to the taste of wine will produce very big effect. Wine must be low temperature fermentation, fermentation suitable temperature for 15 ~ 18 ℃, minimum temperature of 14 ℃, the highest temperature is 20 ℃, and more than 20 ℃ or higher temperature of the wine, aroma is not pure and fresh, delicate taste. So, strictly control the temperature at which the wine is the key in the whole process, so how can we control the temperature of the good wine? Winemaking equipment are usually equipped with a number of bimetallic thermometer, to real-time measure the temperature of the tank. Temperature sensing element in bimetallic thermometer is two pieces of expansion system made of different metal stitch welding together. Bimetallic strip after heat due to the expansion of the two sheet metal bending length is not the same. The length and width of the linear expansion of the higher the temperature the greater the difference, thus draws the greater the bending Angle, the bimetallic strip are made into spiral tube, this is the working principle of bimetallic thermometer.
