Measuring range, charge amplifier Charge, voltage or current range of the signal input. Entry
in units of the measurand is also possible depending on the
type of charge amplifier.
Measuring range, sensor Range in which the quality of the measurement within the
stated tolerances is guaranteed. This range must be re-
garded as a binding maximum range.
Natural frequency Frequency of free (not forced) oscillations of the entire
sensor. In practice the (usually lower) natural frequency of
the entire mounting structure governs the frequency be-
havior.
Operating temperature range Range of ambient temperatures in which the sensor is to
be operated. The temperature-dependent tolerances
stated apply only within this range.
Output signal see "Charge signal"
Overload
Maximum value of the measurand with which a sensor can
be loaded without sustaining damage. This refers to a
safety margin and is not an extended measuring range.
The characteristics specified in the calibration certificate are
no longer guaranteed in the event of an overload. Never-
theless, measurements made during an overload in most
cases provide useful results
pC (picocoulomb) 1 picocoulomb = 10

coulomb. See "Coulomb".
piezoelectric
Characteristic of crystals (e.g. quartz) in which mechanical
loading produces a proportional electrical charge
quasistatic
Describes the ability of Kistler sensors and charge amplifiers
to undertake short-term measurements or DC-similar
measurements.
Range see "Measuring range"
Scaling Output voltage per unit of the measurand at the analogue
or monitor output of a charge amplifier..
Sensitivity Nominal value or calibrated value stated in the calibration
certificate of the change in the response of a sensor divided
by the corresponding change in the value of the meas-
urand.
Note: sensitivity of piezoresistive and strain gauge sensors
is additionally dependent on the excitation current or volt-
age.
Sensor System which produces a definite change in the output
signal as a function of the change of the measurand acting
on it.
Note: The term "Sensor" is equivalent to "Transducer"
Temperature influence see Annex 9.5.
