PRT Care and Handling Guidelines
5.1 PRT
Care
Caution
Read this section before removing the PRT from the shipping
box or case.
The 5626 and 5628 Platinum Resistance Thermometers (PRTs) are delicate
instruments. Care must be taken in handling the PRTs to maintain calibration
accuracy. The stress free design of the PRT sensor reduces the effects of
mechanical shock. In addition, contamination problems of the sensor at high
temperature have been eliminated. However, care should still be used when
handling the PRT even though the Inconel sheath is durable and provides good
protection for the sensor. Correct handling of the PRT will prolong the life
expectancy. When not in use, the PRT should be stored in the protective case
provided.
Note:
The PRT sheath changes color after use at high temperatures. The
PRT may arrive with a brown tint to the sheath due to calibration at
high temperatures.
The handle is not designed to be immersed. The temperature limits of the handle
are: 0
°
C to 80
°
C. Temperatures outside these limits can damage the sealed
portion of the handle and the connectors.
