Introduction
Page 5002-895e-08.22
2. Fundamentals
The typical measuring chain consists of a piezoelectric sensor
withchargeoutput,achargeamplierType5028Aanda
system for signal processing.
In industrial applications, cycle command functionality is
usually implemented with a programmable logic controller
(PLC), using an IO-Link Master to connect conveniently to
theamplier.
2.1 Piezoelectric Measurement
Sensors
Piezoelectric sensors directly convert mechanical quantities,
such as force, pressure and acceleration, into an electric
charge. This charge is proportional to the force acting on the
quartz crystal in the sensor. The sensitivity of the sensors
is given in pC/M.U.
Figure 1: Force F on the piezoelectric sensor
Notes on piezoelectric measurement
When working with piezoelectric instruments, please note
that these dier from other familiar electrical measuring
instruments. The applicable criteria are dierent from
those for conventional current or voltage measurement,
for example. When unpacking the sensors and the special
cables ensure that their connectors remain clean and dry, in
order to maintain their high insulation resistance. In particular,
theTeoninsulatorofallconnectorpairsintheinputcircuit
must be kept absolutely clean and must not be touched
withyourngers.Onlyuseunadulteratedcleaningagents,
for example Type 1003 cleaning spray from Kistler or white
spirits, on a clean, lint-free paper towel.
High insulation sensor cables
Only high insulation, low noise sensor cables, as per Kistler
data sheets 1631C_000-346 and 1601B_000-352, may be
used for connecting the sensors. Normal commercial coaxial
cables generate triboelectricity as a result of movement,
which would falsify the measurement result.
Connecting piezoelectric sensors in parallel
When several sensors are connected in parallel, the charge
ampliermeasuresthesumofallcharges.Forexample,
the four quartz force links of a measuring platform can be
connected in parallel in order to measure the total force.

Polarity
Kistlerdenespolarityinsuchawaythatanincreasein
compressive force in a force sensor produces a negative
charge.Thechargeamplierinvertsthesensorsignaland
in this case generates a positive output voltage.
Measuring range
We recommend setting the widest measuring range at the
start of measurement or for very intermittent operation.
Normal overdriving by overly-large charge signals does not
damagethechargeamplier.Iftheamplierisoverdriven
by a factor of more than 10, the charge can produce an
unacceptably high voltage. The amplitude of the voltage
depends on the input charge, the total input capacitance
(sensor and cable) and the range capacitor.
Measure mode
Themajoradvantageofthechargeamplierprincipleisthat
even quasistatic measurement can be carried out perfectly.
Staticmeasurementislimitedbythenitetimeconstantin
thenegativefeedbackcircuit,aswellasbydrifteects(for
example,inputcurrent)inthechargeamplier.
2.2 The Industrial Charge Amplier
In this context it should be noted that the term “charge
amplier”doesnotmeanadevicethatampliesacharge
Q1 to a value Q2. We use it in the sense of a device for
converting the charge Q into a voltage Ua.Achargeamplier
is therefore a charge-to-voltage converter. It employs the
circuit principle of the integrator. Its key components are
an operational amplier with very high internal gain and
extremely high input insulation (Rg) as well as a high-
precision, low-loss negative feedback capacitor (Cg).
Figure 2: Equivalent circuit diagram of charge amplifier
with charge source
The following approximate formula is adequate for calculating
the voltage signal in most cases:
Ua = -Q/Cg
Fundamentals
Page 7002-895e-08.22
At the end of each measuring cycle the negative feedback
capacitor is discharged by means of the Reset command
and the output signal is set to zero in order to prevent zero
drift during measurement. The insulation resistance of the
negative feedback capacitor Cgdeterminesthelowercut-o
frequencyofthechargeamplieraccordingtotheformula
fu=1/(2τ·Rg·Cg)
The negative feedback capacitor can also be discharged
according to a time constant. This option is available in
thedevice with aprecongured resistor butcan also be
conguredwithadierenttimeconstantonrequest.
Very stringent requirements are imposed on the stability, low
input current and high input insulation of such an integrator,
as the charges to be measured are often just a few pC. As a
result of the high charge sensitivity and high input resistance,
the sensitivity to noise is also relatively high.
In industrial applications, the sensitivity to interference can
bereducedifthechargeamplierismountedascloseas
possible to the sensor. The signal can then be processed
furtheraway,astheoutputcircuitofthechargeamplieris
low resistance and hence insensitive to interference

3.3.4 Connecting Sensors
The sensor input connector allows to connect any piezo-
electric charge output sensor, as well as externally summed
sensorsignals,toType5028Achargeamplier.
The extremely high input insulation of the charge
amplier(>1E13Ohm)meansthesignalorcharge
input has to be protected against dirt and moisture.
Clean the connector contacts with a clean, lint-free
paper towel and Type 1003 cleaning spray or white
spirit.
Connect the cable to the sensor. We recommend
using high-insulation, low-noise cables from the Kistler
range.Thesearetestedspecicallyforhighinsulation
resistance, low noise and low unwanted (triboelectric)
charge produced by friction. If the cable is moved
during operation, it should not be suspended over
spans exceeding 30 ... 50 cm.
Connect the sensor cable to the KIAG 10-32UNF neg.

CAUTION
Assensorconnector,amplierhousingandIO-LinkGroundare

to take countermeasures against ground loops.
Kistler provides insulation elements for sensors as well as ground
insulationkitsavailablefortheType5028Aamplierseries.
Seesection“3.3.2Installation”formountingrequirements.
Piezoelectric sensors are usually designed so that one of
the electrodes is connected on the sensor case, allowing
the use of coaxial cables. When the sensor is installed, it
is usually grounded by the metal structure (safety). If the
sensor is not insulated when it is installed, a resultant ground
loop could cause interference.

NOTE
It is highly recommended to use the Operate status bit to verify
proper reset of the measuring channel, in order to respect
state machine behavior. Discharge of the signal is given by
physical means. Violating the reset-time may result in incorrect
measurement data.

Always verify your setting from the device after a change.
Units
Default = M.U.
The Units parameter is not relevant to the measurement

functionality of the device and only serves the indication of
the measured physical units. The parameter is not included
inthesmartsensorrecognitionbutmustbeveriedmanually
with the Units parameter.
Range Analog Output
Default = 10 [V]
Using the analog signal output on Pin 2 may require limiting
the maximum signal output between 1 V … 10 V depending
on the receiving system. By default, the Range Analog Output
is set to 10 V, resulting in: +/-User Range = +/-10 V.
In case of exceeded measuring range, the output signal

103%oftheconguredRangeAnalogOutputVoltage.
Low-Pass Filter
Default=o/6.25k[Hz]
By limiting the upper bandwidth levels, unwanted high
frequency signals and noise may be reduced or eliminated.
However,lowerltersettingsresultinlongersignaldelays,
caused by physical and mathematical reasons. Please see
specicationforresultingdelayduetoltering.TheLow-Pass
Filter shall not be changed during an ongoing measurement.
Time Constant
Default=o
The time constant of 60s continuously discharges the internal
capacitor, still allowing to acquire periodic processes of
approx.1sdurationwithlessthan0.8%relativedeviation.The
Time Constant may be activated any time upon requirement
of the application. Fast processes as well as continuous
relative signals may not allow to reset the amplier to
eliminatedrifteectsbetweenprocessperiods.
Measure High or Low Active
UsingtheAmplierwithoutanIO-LinkMaster,thedevicewill
automatically use Pin 4 as reset/measure Input. By default,
Pinlevelsaredenedreset=lowandmeasure=high=

Functionality depends on Parameter: Switch Point Mode and

in detail within the IO-Link Specication which may be
downloaded from:

NOTE

value than switch Point 1 level.
Mode: deactivated
Setpoint values are ignored but shall be set to zero default
values in order to not inuence range conguration limit
validation.
Mode: Single Point
The switching state changes, when the current measurement
value passes the Setpoint SP1. This change occurs with
risingorfallingmeasurementvalues.Ifahysteresisisdened
for SP1, the switching behavior shall observe the hysteresis
as shown
Mode: Window Mode
The switching state changes, when the current measurement
value passes the Setpoint SP1 and Setpoint SP2. This
change occurs with rising or falling measurement values.
If hysteresis is dened for SP1 and SP2, the switching
behavior shall observe the hysteresis as shown. This
behavior shows symmetrical hysteresis in respect to SP1
and SP2 and High-active switching. Switch Point 1 and
Switch Point 2 bit are equal and will be set simultaneously.
Mode: Two Points
The switching state changes, when the current measurement
value passes the Setpoint SP1. This change occurs only
with rising measurement values.
The switching state changes also, when the current
measurement value passes the Setpoint SP2. This change
occurs only with falling measurement values. Hysteresis
shall be ignored in this case.
Switch Point Hysteresis
In Single Point and Window Mode, this Parameter allows
toavoidunwantedickeringoftheSwitchPointbitsduring
slow transitions over Switch Point levels.
Reset to Measure Jump Correction
This Bit enables internal subtraction of the reset to measure
jump,resultinginreducedzerooset,whichreduceserrors
for small signal measurements.
