Steel pointer index is used to show the temperature of reading in maximum and minimum thermometer, why ?
1 Answer
Once the reading has taken, the indices must be drawn down to reset for the next observation with help of magnet and steel pointer is magnetic substance which is easily attracted by the magnet. So, steel pointer is used in maximum minimum thermometer.
Six's maximum and minimum thermometer is a popular thermometer among gardeners for use in greenhouses. Its purpose is to record the maximum and minimum. Registers maximum and minimum temperatures in both °C (range: −40 to 50° with 1° divisions) and °F (range: −40 to 120° with 2° divisions).A maximum–minimum thermometer. The scales are Fahrenheit on the inside of the U and Celsius on the outside. The current temperature is 23 degrees Celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the U tube. The bulbs are hidden by a plastic housing.
Six's Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. One side registers the maximum temperature and the other side records the minimum temperature. The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol.Identify the lowest number in the data set, as well as the highest number. Subtract the lowest number in the set from the highest number. The resulting value is the range of the set of temperature values.
Atmospheric temperature range is the numerical difference between the minimum and maximum values of temperature observed in a given location. A temperature range may refer to a period of time or to an average. ... The average temperature range is 11.4 degrees.MAXIMUM TEMPERATURE: The definition of maximum is the largest number or highest number of something that is permissible or possible. MINIMUM TEMPERATURE: The lowest temperature recorded—diurnally, monthly, seasonally, or annually, or the lowest temperature of the entire record.
In order to calculate your maximum case temperature, first multiply the amount of heat the device dissipates by the junction-to-case thermal resistance to get the temperature rise from the junction to case. Then subtract this temperature rise from the maximum junction temperature to get the maximum case temperature.
