Bimetal thermometer calibration.
The primary principle probe about thermostats. It is based because two strips of various metals that are bonded together a change of any temperature cause the strip to bend. It is used to measure temperatures in foods staffs. It measures temperature through across a metal stem that has a sensor in the lower end. It as a sensing area from the tip past the dimple that is used for sensing. It has the adjustable calibration nut that makes the temperature quickly to read (Chaldecott, 1972 p 58). When calibrating the thermometer, there is always; a set point is used to close the testing temperature as possible. If the thermostat is used in a comprehensive, range reading the calibration that is near to midpoint are chosen — for example, taking about Tel-Tru Dual Gauge thermometer, that has a scale of 0 to 220 F (Hewson, 1975 p 350).
Introduction.
Bimetal thermometer is used in the measurement of foods staffs and drinks. It has different calibration such as 32F. Using the calibration one-need accurate thermometer that can be trusted. Using spirit-filled thermometer is very precise because it can be adjusted and it can use ice bath (32F) or using the boiling point 212 at sea level (Hewson, 1975 p 351). The range for the bi-metal thermometer varies from 32F to 212F because the accuracy is always applied at the end of the range. MT500 thermometer that has six probes should be submerged at 2.5 inches in the fluid so that one can get a better reading (Chaldecott, 1972 p 58).
Results.
Increase in references temperature increases the indicated temperature.
Conclusion.
Bi-metallic thermometer calibration is used to measure food staff and drinks. The thermometer has an accurate range that is used in measurements. The experiments show that when the references temperature is increased in BI metal thermometer, the indicated temperature also increased.
