We now have 90 degree angled probes to a maximum temperature of 660 c.
Industrial platinum resistance thermometer.
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.
These industrial platinum resistance thermometers are ideal for field and lab use.
A platinum resistance thermometer contains thin platinum wires surrounded by mica or ceramic material.
The relative change in resistance temperature coefficient.
With decades of experience in metrology our team has a passion for making great products using the most cutting edge technology available.
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.
1 1 this specification covers the requirements for metal sheathed industrial platinum resistance thermometers prt s suitable for direct immersion temperature measurement.
Resistance temperature relationship of metals.
Suitable for use as working standards in dry blocks and liquid baths or as high accuracy probes for our range of true temperature indicators.
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.
The temperature measurement through platinum resistance thermometer is easier as compared to the gas thermometer.
The electrical resistance of metals increases with the temperature.
This second edition cancels and replaces the first edition published in 1983 amendment 1 1986 and amendment 2 1995.
The industrial type thermometer is shown in the figure below.
This property is particularly pronounced in platinum pt.
The platinum resistance thermometer is a versatile instrument for temperature measurement in the range from 200 to 1000 c.
The thermometer has a wide range from 200 to 1200 celsius.
It is used both for precision measurements of the highest accuracy and for routine industrial work.
This article discusses the development and construction of resistance thermometers and their uses in a wide range of industries.
