Ro = What tool is used to measure the temperature of a substance? thermometer A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. Temperature Measurement Methods Mechanical or Non-Electric Methods Liquid in glass thermometer change in pressure Constant volume gas thermometer Bimetallic thermometer. Measuring Methods The temperature can be measured mechanically or electronically. F = (9/5 C) + 32 or C = 5/9 (F - 32) 1.6 Quality Control. Temperature Measurement Methods There are several techniques for meas-uring temperature with an RTD. General It will be also noted that the tempera-ture at 417.0 m had not The Concept of Temperature. Both of these effects can be combined to measure temperature. ME 4/549: Temperature Measurement page 3. More details about each of these temperature measuring devices can be found in the related learning module for this course. Ambient temperature in meteorology (also named surface temperature) is measured using a air thermometer under shelter from direct sun radiation, but well ventilated, placed some 1.5 m Lab 10, Temperature Lab Page 3 Objectives 1. Measure the temperature of the furnace intermittently until it reaches the desired temperature and stabilizes.

Connect thermocouple from the calibration cell to a potentiometer and turn the www.PDHcenter.com PDH Course E166 www.PDHonline.org. with a high and negative temperature co-efficient of resistance, sometimes as high as -6% per degree Celsius rise in temperature. A common method of calibrat-ing temperature sensors is to remove them from where they are installed and place them in a dry-well calibrator or a Micro-Bath. The varioustemperature scales are related as follows: F = 1.8C+ 32 C=(F32)/1.8 R = F + 460 K = C + 273. methods . B ody temperature represents the balance between heat produc-tion and heat loss (Marieb and Hoehn, 2010).

The accurate measurement of temperature is a vital parameter in many fields of engineering and scientific practice. If the Numerous practical details provide the user with valuable information ing temperature Temperature measurement Temperature measurement was taken 30-60 minutes after clinic arrival or at least 10 minutes after playing to measurement of temperature assumes new importance. Types of thermometerDigital stick thermometer. A standard digital stick thermometer works just like an old-fashioned glass thermometer, but is safer and more accurate.Ear thermometer. Ear thermometers use an infrared ray to measure the temperature just inside the ear canal. Temporal artery thermometer. Non-contact thermometer. Glass and mercury thermometer. Course Content. process support applications, or the temperature of solid objects such as metal plates, bearings and shafts in a piece of machinery. Digital thermometers tend to be the quickest, most versatile, and cheapest method to measure body temperature. They can be used to obtain oral, axillary, or rectal temperatures, although it is not recommended to use the same thermometer for more than one route. Following a rectal reading, oral readings are the most reliable and accurate. These metals have a positive temperature co-efficient of expansion. Therefore resistance increases as the temperature increases.
