Self-heat coefficient, response times and measurement tolerances
of the temperature sensors
Response times:
The values for t
0.5
and t
0.9
were determined in circulating water (v = 0.4m/sec).
Measurement conditions for self-heat coefficient:
flow velocity for water v = 0.2m/sec and air v = 2m/sec
Self-heating:
A current has to pass through a temperature sensor in order to measure its electrical re-
sistance. This current produces a certain amount of self-heating of the temperature sen-
sor, depending on the external influences. The size of the self-heat error depends on the
power supplied P = I
2
R, the amount of heat dissipated via the measured medium, the
thermal mass of the sensor and its surface area. The specific properties are combined into
a coefficient, so that the self-heat error is given by:
t = l
2
R E
The coefficient E varies with the measurement conditions and changes if the sensor is built
into a protective fitting.
