The working principle of portable bimetallic thermometer

We usually put the header size is less than 50 mm bimetallic thermometer call portable bimetallic thermometer, as the name suggests, it compared with other double metal thermometer, its characteristic is portable portable bimetallic using bimetallic strip to control the change of temperature, in order to measure the a more accurate temperature value. Temperature sensing element including 2 different types of double metal welded together, like coil, then welding in the rear of the heat pipe. Sensors with silicone to protect, prevent it from vibration. At the other end connection at the top of the dial pointer. When the temperature of the heat pipe to change, sensors will be expansion or contraction, and transferred to the pointer will change, so a thermometer can accurately indicate the temperature. The thermometer designed is to make people see the change in temperature. The bimetallic thermometer is help through the different metal heat bilges cold shrink degree of different temperature indicating devices, it requires no energy and is not restricted by regional or medium, can be anywhere at any time to measure the temperature of the measured object. Portable thermometer compact appearance make it acclaimed, and the precision of quality assurance, also let repeat an endless stream.
