Platinum Resistance Thermometer Diagram

A platinum resistance thermometer prt is a thermometer constructed from a high purity platinum element wire wound coil or thin film placed in a tube of metal or glass and sealed with an inert atmosphere and or mineral insulator.

Platinum resistance thermometer diagram. 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. A platinum resistance thermometer prt is a piece of platinum wire which determines the temperature by measuring its electrical resistance. T pt platinum temperature coefficient. 1 716 684 4500 usa toll free.

The insulator deposit on the surface of the glass tube is also used for sensing the temperature. Ag fp the interpolation instrument is a platinum resistance thermometer constructed with a strain free platinum resistance element and meeting certain performance criteria. Platinum resistance thermometers prt characteristics. When manufactured carefully these devices offer an excellent combination of sensitivity range and reproducibility.

It is used both for precision measurements of the highest accuracy and for routine industrial work. In this ptr the double wire of the platinum is wound on the strip of the mica. R t r o r 100 are the resistance at t c 0 c 100 c. Disposal caution scrap temperature sensors as industrial waste.

The platinum sensing coil is enclosed inside a bulb which is either made of glass or pyrex. The storage at in a high humidity place may cause low insulation resistance. This article discusses the development and construction of resistance thermometers and their uses in a wide range of industries. This article discusses the development and.

The relative change in resistance temperature coefficient. The platinum resistance thermometer is a versatile instrument for temperature measurement in the range from 200 to 1000 c. Caution store temperature sensors in dry and clean place. It is used both for precision measurements of the highest accuracy and for routine industrial work.

It is referred to as a temperature sensor. The platinum resistance thermometer a review of its construction and applications by liodney price the platinum resistance thermometer is a versatile instrument for temperature measurement in the range from 200 to 1000 c. The value of δ lies between. The its 90 is realized in the sprt laboratory entirely by fixed points over the range from the ar tp to the ag fp.

Temperature sensors should be stored in a dry and in a clean place. Resistance temperature relationship of metals. The figure below shows the platinum resistance thermometer.
