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 60751.
class
deviation
Temperature range
B
±0.3 °C ±0.5 % of measured value
-50 … +500 °C
A
±0.15 °C ±0.2 % of measured
value
-30 … +300 °C
AA = 1/3 DIN B
±0.1 °C ±0.17 % of measured
value
0 … +150 °C
In order to achieve high exchange accuracy without the necessity of an additional correction,
we recommend using class A or AA temperature sensors.
5.2 Possible measuring errors
5.2.1 Immersion depth
Liquids:
Immerse to a depth of at least 20 mm and then stir.
Otherwise, measuring errors can occur due to the heat transmis-
sion 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 measurement result.
Note
Thermally conductive paste between the measuring sensor and surface can also in-crease
measurement accuracy in some cases.
