Strain-free sensor design by Harts SPRT engineers
If youre using block calibrators, furnaces, or temperature points above normal PRT temperatures (420 °C), then these two PRTs are for you
The 5626 is nominally 100Ω and the 5628 is nominally 25.5Ω
Both instruments have a temperature range of -200 °C to 661 °C
They make great working or check standards for calibration work up to the aluminum point
Using a regular PRT at temperatures above 500 °C exposes the platinum to contamination
If the PRT is used as a reference or calibration standard, contamination is a major problem
SPRTs, which are more expensive and delicate, can handle the higher temperatures, but with greater risk to the instrument due to shock, contamination, or mishandling
The 5626 and 5628 are designed to reduce the contamination risk through the use of internal protection while not impairing performance
