Industrial platinum resistance thermometer.
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.
We now have 90 degree angled probes to a maximum temperature of 660 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.
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.
It uses the property of platinum in which the specific resistance increases with temperature.
The platinum resistance thermometer is a versatile instrument for temperature measurement in the range from 200 to 1000 c.
Methods for evaluating the condition of platinum resistance thermometers 130 23 kb.
The temperature measurement through platinum resistance thermometer is easier as compared to the gas thermometer.
The industrial type thermometer is shown in the figure below.
If you want a very stable thermometer and prefer a probe with optional.
Fluke calibration secondary standard prts fill the gap between affordable but temperature limited secondary reference prts and more expensive highly accurate sprts.
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.
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.
A platinum resistance thermometer contains thin platinum wires surrounded by mica or ceramic material.
The relative change in resistance temperature coefficient.
Accurate temperature measurement and calibration accumac corporation designs and manufactures digital thermometer readouts platinum resistance thermometers prts and thermocouples.
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.
With decades of experience in metrology our team has a passion for making great products using the most cutting edge technology available.
This property is particularly pronounced in platinum pt.
The meter gives the precise reading of temperature.
The thermometer has a wide range from 200 to 1200 celsius.
The electrical resistance of metals increases with the temperature.
Suitable for use as working standards in dry blocks and liquid baths or as high accuracy probes for our range of true temperature indicators.
