Bimetallic thermometers are made up of bimetallic strips formed by joining two different metals having different thermal expansion coefficients. Write. One of the most popular design i.e. Some liquid-filled thermometers can be calibrated by carefully moving the glass stem within the holder. A bimetallic dial thermometer, commonly known as a bimetal thermometer, is installed at the point of measurement and is usually read from that location. The thermoelectric potential of a bimetal thermometer is only related to the thermoelectric properties of the hot electrode material and the temperature difference at both ends. Bimetallic strip thermometers are manufactured in various designs. The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass.The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. However, that is not the only shortcoming of bimetal food thermometers. Also called ‘spirit-filled' or ‘liquid in glass' thermometers, are the oldest type of thermometers. Belt Scales; Integrators; Solids Flowmeters; Speed and Motion Sensors; Weighfeeders; Controllers and Programmers. Types of Thermometers. Thermocouples. Bimetallic Thermometer In an industry there is always a need to measure and monitor temperature of a particular spot, field or locality.
