Thermal Influences - HBM CMD Serie Bedienungsanleitung

Tips for piezoelectric measurement technology
S Clean again with a new cleaning pad.
The cable plugs cannot be cleaned, i.e. if the plug is con­
taminated, the entire cable must be replaced.
Notice
The cleaning agent RMS1, which is used for cleaning SG
installation points, is not suitable for cleaning piezoelec­
tric sensor connections.

14.4 Thermal influences

Influence of sensor temperature on the characteristic
curve
The influence of temperature on the sensitivity of the
sensors is very low, at 0.2% per 10 K, and is negligible
for most applications.
Temperature influences on signal stability
All piezoelectric sensors change their charge state when
the temperature changes, as the pre‐stress changes (the
elastic modulus of the design elements depends on tem­
perature). In addition, temperature fluctuations during
measurement lead to thermally induced stresses that
generate an output signal.
Information
The output signal only changes in the case of a change
in temperature, a charge is not generated under station­
ary conditions.
