Platinum Resistance Thermometer Graph

The temperature measurement through platinum resistance thermometer is easier as compared to the gas thermometer. Thermometers failed to perform to the expected stabilities and so the its 90 reduced the upper temperature of contact thermometry to the silver point 961 78 c 1. Resistance for pt100 sensors pt100 resistance table the chart below can be used as a referencing tool to find the relationship between a range of temperatures and resistance for pt100 rtd sensors temperatures in multiples of ten can be found down the left axis whilst for more precise readings you must move along the horizontal axis between one and nine.

Platinum resistance thermometer graph. In preparation for the its 90 many national laboratories designed platinum resistance thermometers that would work to the gold point of 1064 c. The thermometer has a wide range from 200 to 1200 celsius. Select the data points. The condensed resistance vs temperature tables on the following pages are provided to aid in the proper rtd element selection.

In the drop down click the 2d clustered column chart. The meter gives the precise reading of temperature. Here are the steps to create a thermometer chart in excel. In fact the platinum resistance temperature detector or rtd pt100 is used today as an interpolation standard from the oxygen point 182 96 c to the antimony point 630 74 c.

Common rtd sensing elements constructed of platinum copper or nickel have a repeatable resistance versus temperature relationship r vs t and operating temperature range the r vs t relationship is defined as the amount of resistance change of the sensor per degree of temperature change. In the charts group click on the insert column or bar chart icon. Table 30 100 ω platinum rtd 0 003 85 coefficient temperature in f f 0 1 2 3 4 5 6 7 8 9 10 f resistance in ohms f 0 1 2 3 4 5 6 7 8 9 10 f 114 pt f 150. 1 716 684 4500 usa toll free.

The thermometer is quite sensitive. These thermocouples are well suited for measuring extremely high temperatures. Click the insert tab. To calculate the resistance of.

This would insert a cluster chart with 2 bars as shown below. Starting with its 90 platinum resistance thermometers have taken over this range as standard thermometers. The relative change in resistance temperature coefficient. Resistance temperature relationship of metals.

His choice proved most propitious as platinum is used to this day as the primary element in all high accuracy resistance thermometers. With the chart selected click the design tab. Typical uses are hydrogen and inert atmospheres as well as vacuum furnaces. 200 ohm multiply the values by 2.

Notice that the tables for the various platinum curves are for the standard 100 ohm 0 c sensor.
