Fundamentals

Page 75074B_002-942e-09.20

2. Fundamentals

The typical measuring chain consists of a piezoelectric sen-

sor with charge output, a charge ampliﬁer and a system for

cycle command, data acquisition and data evaluation.

In industrial applications, cycle command functionality is

usually implemented with a programmable logic controller

(PLC).

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 sen-

sors is given in pC/M.U.

Fig. 3: Force F on the piezoelectric sensor

5074B_002-942e-09.20Page 8

Notes on piezoelectric measurement

When working with piezoelectric instruments, please note

that these differ from other familiar electrical measuring in-

struments. The applicable criteria are different from those

for conventional current or voltage measurement, for ex-

ample. 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 cir-

cuit 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 spir-

its, 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 coax-

ial 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 con-

nected 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.

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 quasi-static 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.

Fundamentals

Page 95074B_002-942e-09.20

2.2 The industrial charge ampliﬁer

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

pliﬁer" does not mean a device that ampliﬁes a charge Q1

to a value Q2. We use it in the sense of a device for con-

verting 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-preci-

sion, low-loss negative feedback capacitor (Cg).

Fig. 5: Equivalent circuit diagram of charge ampliﬁer with

charge source

The following approximate formula is adequate for calcu-

lating 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 nega-

tive feedback capacitor Cg determines the lower cut-off fre-

quency of the charge ampliﬁer according to the formula

fu = 1/(2τ · Rg · Cg )

The negative feedback capacitor can also be discharged ac-

cording to a time constant. This option is available in the

device with a preconﬁgured resistor but can also be conﬁg-

ured with a different time constant on request.

Very stringent requirements are imposed on the stability,

low input current and high input insulation of such an inte-

grator, 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.

3. Description of the Type 5074 charge ampliﬁer

All communication, conﬁguration and user data is transmit-

ted exclusively via the industrial Ethernet, making the de-

vice easily applicable for machine and equipment builders.

No additional software is required but the already known

programming interface of the machine control system.

Know-how about PLC system setup, programming and de-

vice integration is required.

Integration into the control environment is carried out as

with a standard ﬁeldbus device using the programming in-

terface of the PLC manufacturer and the device description

ﬁle which is provided by Kistler.

Functions and parameters

The feature set of the 5074B... may be conﬁgured to meet

the effectively required functionality. Parameters are set us-

ing the startup conﬁguration parameters. Changes on these

channel conﬁguration parameters may be sent to the de-

vice during an active measurement, but require a measure-

reset-measure toggle and will be activated with the next

measuring cycle.

Inﬂuencing and adapting the process data

The processing of many analog values under short cycle

times can dramatically increase the utilization of the net-

work. The 5074B enables the ﬂexible adaptation of the pro-

cess image and thus an optimization of the network utiliza-

tion according to customer requirements. Possible measures

to reduce the process data are:

- Use of 16Bit values instead of 32Bit

- Disable unnecessary data (e.g. ﬂoating point values,

integral and peak values)

Refer to Section 4.2 for more details regarding PLC integra-

tion, channel control and conﬁguration:

- Scaling of the input signals

- Measurement range setting

- Adjustable low-pass ﬁlter

- Oversampling factor

- Time constant, high-pass ﬁlter

- Peak tracking

- Integral calculation

4. Commissioning

Do never open the device.

Moisture and particles would be able to enter the device

and may cause errors and drift.

4.1 Installation

To mount the ampliﬁer, use the ﬂange marked on the

graphic and M4 Cylinder Head Screws.

See Chapter 4.1.3 for details on EMC and ground-loop.

4.1.1 Connecting sensors

Depending on the version, one, two, three or four sensors

can be connected to the 5074B charge ampliﬁer.

The extremely high input insulation of the charge am-

pliﬁer (>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 speciﬁcally for high insulation resistance,

low noise and low unwanted (triboelectric) charge pro-

duced 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.

jack of the industrial charge ampliﬁer.

4.1.3 Network and power connection

The internal switching type power converter is built up

with galvanic insulation. This provides additional immunity

against noise generated by other slave devices connected to

the same power supply.

The power output connector allows power routing through

the cascaded devices to have multiple slave devices con-

nected in a line. However the current routing through the

5074B is limited to 1.5A.

4.1.4 EMC and ground loops

Piezoelectric sensors are usually designed so that one of the

electrodes is connected on the sensor case, allowing the use

of coaxial cables. So when the sensor is installed, it is usu-

ally grounded by the metal structure (safety). If the sensor

is not insulated when it is installed, a resultant ground loop

could cause interference.

There are different countermeasures if EMC or ground

loops occur:

A low-impedance and at the same time low-inductance

connection between instrument case and sensor (large-ar-

ea copper braiding, ribbon cable) usually provides good re-

sults.

On the other side, the sensor may also be installed using

insulation elements to eliminate current ﬂow based on po-

tential differences or induction.

Since network and power connection are galvanically insu-

lated, there shall be a deﬁned connection of the measuring

chain to a ground level.

Potential differences from sensor to ampliﬁer mounting

area

On single channel 5074B1xx device, either sensor or am-

pliﬁer shall be connected to ground, in order to not have a

ﬂoating measurement system.

Commissioning

Page 175074B_002-942e-09.20

Potential differences between sensor inputs

On multi-channel 5074B2xx, 5074B3xx and 5074b4xx it is

important to consider, that sensor connector grounds are

internally connected and capacitive coupled to the housing.

It is therefore recommended to electrically insulate the sen-

sors in order to prevent electrical current ﬂow due to po-

tential differences between sensor locations, or to take ade-

quate counter measures.

4.2 PLC integration

The device is conﬁgured for each channel initially with the

user parameters or during operation using acyclic commu-

nication. The ﬁeldbus provides the following data as cyclic

data:

Channel data blocks 1 to 4 are optional depending on the

use by the customer.

The cyclic output data block contains individual control bits

for each channel. Control bits are processed internally and

then conﬁrmed with the status bits contained in the input

data block that is sent to the master with every cycle.
