Technology and instrumentation are inseparable. In order to help everyone further understand the basic knowledge of instrumentation, we have launched a (one question per day) activity, and you can view it by replying. To encourage everyone to continue to participate! Participate and get 3 wealth rewards! I hope everyone will actively participate and learn together * , make progress together! ! ! true or false question: 22. Are the following statements correct? Bimetal thermometer is a solid expansion thermometer that uses the geometric displacement generated by heating of a solid as a measurement signal. The main component of an industrial bimetal thermometer is a multi-layer metal sheet composed of two or more metal sheets laminated together. It works based on the principle that two different metals expand to different degrees when the temperature changes. It is based on a bimetallic sheet wound into a circular bend. When one end is heated and expands, the pointer is driven to rotate, and the working instrument displays the temperature value corresponding to the thermoelectric potential. The answer to this question is: right
