What is a bimetallic thermometer used for?
Bimetallic thermometers are widely used in industry. Their typical range is from 40–800 (°F). They are often used for two-position temperature control in residential and industrial thermostats.
How does a bimetallic thermometer work?
Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale.
Where are bimetallic strip thermometers often used?
Bimetallic thermometers are used in residential devices like air conditioners, ovens, and industrial devices like heaters, hot wires, refineries, etc. They are a simple, durable, and cost-efficient way of temperature measurement.
What foods are bimetallic stemmed thermometers used for?
These thermometers show the temperature with a dial. They can take as long as 1-2 minutes to register the correct temperature. The bimetal stem thermometer can accurately measure the temperature of relatively thick or deep foods such as beef roasts and foods in stockpot.
What is a rotary thermometer used for?
They can be used to observe that heat flows by conduction, convection, and radiation. In medical applications, liquid crystal thermometers may be used to read body temperature by placing them against the forehead.
Where are resistance thermometers used?
Due to their accuracy and robustness, they are extensively used as in-line thermometers in the food industry. Within a wide range of temperatures the resistance of metals increases linearly with temperature. The measuring element is usually made of platinum.
What is bimetal thermostat?
Bimetal Thermostats use two different kinds of metal to regulate the temperature setting. When one of the metals expands more quickly than the other, it creates a round arc, like a rainbow. As the temperature changes, the metals continue to react differently, operating the thermostat.
How do thermopiles work?
A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature.
