Industrial Platinum Resistance Thermometer
Suitable for use as working standards in dry blocks and liquid baths or as high accuracy probes for our range of true temperature indicators.
Industrial platinum resistance thermometer. The platinum resistance thermometer is a versatile instrument for temperature measurement in the range from 200 to 1000 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. An investigation into the stability of industrial platinum resistance thermometers 262 44 kb an investigation of long term stability of a precision platinum resistance thermometer up to 660 c 164 52 kb i just got my probe recalibrated now what. 1 1 this specification covers the requirements for metal sheathed industrial platinum resistance thermometers prt s suitable for direct immersion temperature measurement.
The thermometer has a wide range from 200 to 1200 celsius. Resistance temperature relationship of metals. With decades of experience in metrology our team has a passion for making great products using the most cutting edge technology available. The industrial type thermometer is shown in the figure below.
The temperature measurement through platinum resistance thermometer is easier as compared to the gas thermometer. These industrial platinum resistance thermometers are ideal for field and lab use. This second edition cancels and replaces the first edition published in 1983 amendment 1 1986 and amendment 2 1995. It uses the property of platinum in which the specific resistance increases with temperature.
This article discusses the development and construction of resistance thermometers and their uses in a wide range of industries. If you want a very stable thermometer and prefer a probe with optional. It applies to prt s with an average temperature coefficient of resistance between 0 and 100 c of 0 385 c and nominal resistance at 0 c of 100 ω or other specified value. Methods for evaluating the condition of platinum resistance thermometers 130 23 kb.
It is used both for precision measurements of the highest accuracy and for routine industrial work. The relative change in resistance temperature coefficient. Fluke calibration secondary standard prts fill the gap between affordable but temperature limited secondary reference prts and more expensive highly accurate sprts. The 5626 5628 probes provide a calibrated accuracy of 0 006 c at 0 c with a range of 200 to 661 c and include an accredited calibration.
The electrical resistance of metals increases with the temperature. The meter gives the precise reading of temperature. The standard covers resistors or thermometers for all or part of the temperature range 200 c to 850 c with different tolerance classes which may cover restricted temperature ranges. This property is particularly pronounced in platinum pt.
