Cable capacitance The cable capacitance, and thus the length of the con-
necting cable, has no noteworthy influence on the meas-
uring result when Kistler special cables and Kistler charge
amplifiers are used.
Calibrated range
Measuring range or part of the measuring range for which
the sensor has been calibrated.
Note: Because of the high linearity of quartz crystal sen-
sors, the sensitivity of a measuring range can usually also
be used for smaller measuring ranges.
Calibration certificate
Document for sensors and devices stating the results of the
factory calibration.
Charge amplifier
Part of a measuring chain which converts the charge signal
from the sensor into a proportional voltage signal or cur-
rent signal.
Note: The linearity of charge amplifiers is typically within
the range of ±0,01 % of the measuring range selected. For
the accuracy of the measurement, this is usually negligible
compared with other influence quantities.
Charge signal
Physical quantity which a piezoelectric sensor yields on its
mechanical load.
Coulomb
Unit of electric charge.
1 coulomb corresponds to 1 Ampere-second (1 C = 1 As).
Crosstalk
Signal at the output of a sensor, produced by a measurand
acting on the sensor, which is different from the meas-
urand assigned to this output. For example, when a load in
the F
y
direction produces an F
z
signal in a three-component
sensor.
In terms of electrical devices, it is a measure for the signal
impact acting from a channel to the neighbouring ones.
Degree of protection Protection of electrical equipment by suitable enclosures,
covers etc. according to EN60529. The protection class is
stated by IP (International Protection) followed by two dig-
its. The first digit stands for protection against touching
and the ingress of solid bodies, the second for the degree
of protection against the ingress of water.
