Solar thermometer and bimetallic thermometer which is really good

Solar thermometer and bimetallic thermometer which good? The answer is good, each have each their advantages. Below small make up to you to introduce these two thermometer. Solar thermometer application: food industry, machinery and equipment of the factory. Solar electronic thermometer is the use of day Yang can provide accurate temperature indicating and wired sensors. It is the light level is higher than 100 lux show, when the light levels drop, using the backup battery to provide power to continue to display circuit. It has a bright, easy to read LCD display. Bimetallic thermometer application: chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. Bimetallic thermometer is to put the two different linear expansion coefficient of metal together, one end fixed, when the temperature changes, the two different kinds of metal thermal expansion, drive the pointer to indicate the temperature, this is the bimetallic thermometer, page as shown in figure. Temperature range for - 80 ~ 500 c, it is suitable for industrial temperature measurement accuracy is not high. Bimetallic strip as a temperature sensing element can also be used for automatic temperature control.
