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.
Industrial platinum resistance thermometer.
We now have 90 degree angled probes to a maximum temperature of 660 c.
The industrial type thermometer is shown in the figure below.
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 meter gives the precise reading of temperature.
This property is particularly pronounced in platinum pt.

Fluke calibration secondary standard prts fill the gap between affordable but temperature limited secondary reference prts and more expensive highly accurate sprts.
The thermometer has a wide range from 200 to 1200 celsius.
The temperature measurement through platinum resistance thermometer is easier as compared to the gas thermometer.
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.
Resistance temperature relationship of metals.
If you want a very stable thermometer and prefer a probe with optional.
With decades of experience in metrology our team has a passion for making great products using the most cutting edge technology available.
This article discusses the development and construction of resistance thermometers and their uses in a wide range of industries.
A platinum resistance thermometer contains thin platinum wires surrounded by mica or ceramic material.
The electrical resistance of metals increases with the temperature.
It uses the property of platinum in which the specific resistance increases with temperature.
These industrial platinum resistance thermometers are ideal for field and lab use.
It is used both for precision measurements of the highest accuracy and for routine industrial work.
1 1 this specification covers the requirements for metal sheathed industrial platinum resistance thermometers prt s suitable for direct immersion temperature measurement.
Accurate temperature measurement and calibration accumac corporation designs and manufactures digital thermometer readouts platinum resistance thermometers prts and thermocouples.
Suitable for use as working standards in dry blocks and liquid baths or as high accuracy probes for our range of true temperature indicators.
