5 Measurement Basics
5.1 Sensor/device accuracy
The device can be equipped with different interchangeable sensors. The temperature sen-
sors are divided into the following classes according to EN 60584-2.
class
deviation
temperature range
1
±1.5 °C or ±0.4 % of measured value *
-40 … 1000 °C
2
±2.5 °C or ±0.75 % of measured value *
-40 … 1200 °C
3
±2.5 °C or ±1.5 % of measured value *
-200 … 40 °C
* = larger value counts
The system accuracy of the measuring chain (device + probe) is the sum of the accuracy of
the probe and the accuracy of the characteristic curve and cold junction of the device.
5.2 Possible measuring errors
5.2.1 Immersion depth
Liquid:
Immerse to a depth of at least 20 mm and then stir. Otherwise,
measuring errors can occur due to the heat transmission of the
sensor tube if the immersion depth is too shallow.
Gas:
Immerse as far as possible into the gas to be measured so that the
measuring sensor is subjected to a heavy flow.
5.2.2 Surface effects and poor heat transfer
Special measuring sensors are required for this purpose. Surface characteristics, de-sign of
the measuring sensor, heat transfer and environmental temperature influence the measure-
ment result.
Note
Thermally conductive paste between the measuring sensor and surface can also in-crease
measurement accuracy in some cases.
