4. Fundamentals

4.1 The measuring chain

The typical measuring chain consists of a piezoelectric

sensor with charge output, a charge amplifier and a system

for cycle command, data acquisition and data evaluation.

In industry, cycle command functionality is usually

implemented with a programmable logic controller (PLC).

4.2 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.

Fig. 3: Force F on the piezoelectric sensor

Notes on piezoelectric measurement

When working with piezoelectric instruments, please note

that these differ from other familiar electrical measuring

instruments. The applicable criteria are different 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 Teflon insulator of all connector pairs in the

input circuit must be kept absolutely clean and must not be

touched with your fingers. Only use unadulterated

cleaning agents, for example 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 amplifier 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 defines polarity in such a way that an increase in

compressive force in a force sensor produces a negative

charge. The charge amplifier inverts the sensor signal and in

this case generates a positive output voltage. The charge

amplifier does not offer an option for additional signal

inversion.

ICAM – Industrial Charge Amplifier for Manufacturing Applications Type 5073A...



Page 14 5073A_002-327e-04.23

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 amplifier. If the

amplifier 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 amplifier principle is

that even quasistatic measurement can be carried out

perfectly. Static measurement is limited by the finite time

constant in the negative feedback circuit, as well as by drift

effects (for example, input current) in the charge amplifier.

4.4 The Industrial charge amplifier

In this context it should be noted that the term "charge

amplifier" does not mean a device that amplifies 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. A charge

amplifier is therefore a charge-to-voltage converter. It

employs the circuit principle of the integrator. Its key

components are an operational amplifier with very high

internal gain and extremely high input insulation (Rg) as well

as a high-precision, low-loss negative feedback capacitor

(Cg).

Fig. 5: 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

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 Cg determines the lower cut-

off frequency of the charge amplifier according to the

formula

fu = 1/(2 · Rg · Cg)

The negative feedback capacitor can also be discharged

according to a time constant. This option is available 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 amplifier is mounted as close as

possible to the sensor. The signal can then be processed

further away, as the output circuit of the charge amplifier is

low resistance and hence insensitive to interference. Due to

ICAM – Industrial Charge Amplifier for Manufacturing Applications Type 5073A...



Page 16 5073A_002-327e-04.23

the typically metallic shielding of the sensors, cables and

amplifiers, as well as options regarding the grounding

concept, piezoelectric measuring chains from Kistler can

generally achieve high resistance to interference.

In summary, an industrial charge amplifier should have the

following properties:

 Compact

 Robust, sealed housing

 Remote-controlled measurement start and stop

 Low-voltage power supply

 Several measuring channels

 Quick and easy parameter setting

 Adaptable to suit special measuring tasks

5073A_002-327e-04.23 Page 17

5. Description of amplifier

5.1 General

The charge signal coming from the piezoelectric sensor is

converted by the ICAM Type 5073A… (Industrial Charge

Amplifier Manufacturing) charge amplifier into a

proportional output voltage. The output signals can be

passed on to an industrial control system for monitoring,

control and optimization of a production process. During

the process, the amplifier is controlled via digital inputs and

a serial interface.

Models are available with the same case and bolt

pattern but one, two, three or four channels, each of

which accommodates one sensor.

The Type 5073A5xx ICAM has an integrated summing

amplifier to which up to four sensors can be connected

via the input channels. The amplifier operates like a

single-channel version, where the individual charges of all

four channels are summed into a total charge.

Note therefore, for example, that depending on the total

charge of all the channels, the frequency response can

also change.

The charge input is protected against static discharge and is

ground-isolated. It is allowed to have a potential difference

of up to 4 volts relative to the output or supply voltage.

The ICAM has a rugged pressure diecast aluminum case.

With a wide voltage input range from 18 ... 30 VDC and

degree of protection up to IP60/65, the amplifier is desig-

ned for an industrial environment and mounting in the

immediate vicinity of sensors, for example right alongside a

machine tool.

Page 18 5073A_002-327e-04.23

Fig. 6: ICAM Type 5073A...

The ICAM parameters are set with ManuWare PC

software. Virtually any measuring range can be set. For

each sensor connection, two measuring ranges are

available that can also be switched during measurement.

However, for technical reasons this is only permitted

between ±100 to ±10 100 pC and ±10 100 ... ±1 000 000

pC, as otherwise measuring errors will occur. With the

stored peak value, the optimum measuring range can be

determined and hence the highest resolution set. An offset

can be configured for each channel. A low-pass filter can

also be connected. Its cut-off frequency is always valid for

all channels.

Only two peak memory outputs are available on the

version with four channels.

The LED indicates the operating mode of the industrial

charge amplifier. If the ICAM is in Measure mode, the LED

is constantly green. Flashing green indicates Reset mode.

The LED flashes red if the amplifier has been overloaded,

i.e., if the sensor has generated more charge than the

ICAM can accept based on the preselected measuring

range. This can lead to measuring errors. A reset restores

the original state, i.e., the charge amplifier output is set to

zero. The LED is constantly red if the ICAM is faulty.
