7.9 Some Basics of Precision Temperature Measuring
Probe Precision/Device Precision
The device is very precise (please refer to technical data). To be able to use this
high precision, the connected temperature probe has to be as precise as
possible, too. The following precision classes are available as a standard at
reasonable prices (Platinum resistor thermometers according to EN60751):
Class
Error ranges
B
± (0,3 + 0,005 • |temperature|)
1/3 B (=1/3 DIN)
± (0,1 + 0,0017 |temperature|)
1/10 B (=1/10 DIN)
± (0,03 + 0,0005 • |temperature|)
A
± (0,15 + 0,002 • |temperature|)
Error over measuring range
Error over range -50...150 °C
For applications demanding higher precision than given by these classes we
suggest to adjust the device to the used probe or to get a calibration certificate for
the device combined with the probe.
Attention: if an adjusted or calibrated probe is replaced, also the
adjustment or calibration certificate has to be renewed to maintain the
referring overall precision! Be careful when buying third party temperature
probes: Besides the standard EN60751 there are some other obsolete or
unusual standards on the market. If such a probe has to be connected, the
user sensor curve (have a look to the referring chapter) can be used to
adjust the instrument!
