Bimetals are used for temperature indication as in the spiral or helix actuated pointer thermometers. Thermometer, instrument for measuring the temperature of a system. In this simple circuit, a bimetallic contact switches on and off as it's cooled by a fan and heated by a candle. The bimetal thermometer has been used by humans for over 200 years and continues to be an accurate and reliable source to gauge the temperature of food or other materials. The thermometer works by measuring the temperature of the air or liquid around it. How Do Digital Thermometers Work? Not all thermometers work this way, however. In non-digital thermostats there are two switches.These switches move small metal balls that make contact between different traces on the circuit card inside the thermostat. It shall work normally in the ambient temperature of -30℃ ~ 80℃. One of the switches controls the mode (heat or cool), while the other switch controls the circulation fan.On the next page, we'll see how these parts work together to make the thermostat work. The Bimetal thermometer employs a bimetal strip in the form of helix (it works on the principle of thermal expansion - two metals having different coefficient of expansions are joined to form a bimetal. 1, the bimetal thermometer in the storage, installation, use and transportation process, should avoid collision protection tube, do not make the protection tube bending, deformation. It has numerous commercial uses, but the primary purpose of the device is to measure the amount of water vapor (humidity) in the air. Bimetal Thermostat from a Clothing Iron. flat spiral is shown in the figure below. Bimetallic strip thermometers are manufactured in various designs. The thermometer provides high quality and performance, and is an ideal choice in the process industries. Bring it together. A thermocouple is the devise used extensively for measurement of the temperature of the body. The invention of the thermometer is generally credited to Galileo. There are 3 temperatures of interest to the motorist; that of the water in the cooling system, that of the engine lubricating oil and that of the outside air.As auto manufacturers enhanced the dashboards from the rudimentary speedo and fuel gauge, they used two types of gauge: the mechanical and the electrical. The coefficient of thermal expansion is not equal. Thermometers used to be simple. How Thermostatic Bimetal Works Thermostatic Bimetal is a composite material, usually in the form of a strip or sheet, made up of two or more metallic layers having different coefficients of expansion. The one shown in our top photo has a metal pointer that moves up and down a circular scale. The Temperature Adjustment Cam moves the Contacts. 2. Bimetal thermostatic control in photo, removed from an electric iron, il­ lustrates the principle shown in the series of three drawings. The model TG53 bimetal thermometer has been developed and manufactured in accordance with the ASME B40.200 standard. A thermometer has two important elements: (1) a temperature sensor (e.g. 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.
