for your personal safety during work with the Signal

Conditioning Platform (SCP) and to ensure long term,

fault-free operation of this unit.

2.1 For Your Safety

This product has been manufactured in compliance with

the currently valid safety regulations. It meets all relevant

regulations according to the attached conformity declara-

tion. It has left the factory in a perfectly safe condition. In

order to maintain this condition and ensure safe operation,

compliance is required with the instructions and warning

notes contained in these Operating Instructions or imprin-

ted on the product.

Please also comply with the local safety regulations concer-

ning the handling of electrical and electronic equipment.

If it is to be assumed that safe operation is no longer

possible, the equipment must be shut down and made safe

against being accidentally started up.

Safe operation is no longer possible when the product

 shows visible signs of damage

 is no longer operating

 has been in lengthy storage under unsuitable conditions

 has been subjected to rough transport conditions.

If safe operation can no longer be guaranteed, the product

must be returned immediately to the manufacturers or to

the authorized distributor for repair.

Whenever the product is connected to the power supply,

live parts can be exposed if covers are opened or if parts

are removed – except when this is possible by hand.

Adjustment, maintenance and repair work on exposed, live

parts must be avoided as far as possible. If, however, such

work is unavoidable, it must be undertaken only by a

skilled person who is familiar with the dangers involved.

2.2 Notes Concerning the Product

Check all packaging for visible transport damage. Report

any such damage to the transporters and to the authorized

Kistler distributor/sales outlet.

Please check the scope of delivery before first use of the

equipment. Report any missing parts to the authorized

Kistler distributor/sales outlet.

Carry out the following safety precautions if the product is

to be transported or stored for a lengthy period of time:

 Cover all BNC, Fischer and triax connections with the

dust caps supplied.

 Make sure that no dirt can enter the product.

 The environment should be as dry and free from

vibrations as possible.

 Place the product so that neither its front nor rear side

can be subjected to pressure.

 If possible, store the product in its original packaging.

Comply with the requirements for ambient temperature for

storage and operation as stated in the technical data. If, for

example, the ambient temperature is exceeded to a

significant extent, this can permanently damage the

product.

Protect the inputs and outputs of the product against

contamination. Keep the plug-and-socket connections

clean and dry. Fit the cap supplied when a connector is not

being used.

The piezoelectric sensor and the coaxial cable connected to

it have extraordinarily high insulation values. As a result,

when an amplifier is not connected, a high voltage due to

a static charge can occur. In order to avoid damage when

connecting the amplifier, you can short-circuit the cable

directly in front of the connection with a suitable instru-

ment (such as a BNC short-circuiting cover neg., Kistler

Type 1865).

Carry out work with the product only under the specified

operating conditions. Protect the SCP against dust and

mechanical stress such as shock and vibration. Avoid high

atmospheric humidity and changes in temperature which

could lead to condensation.

Safety Notes

2853A_002-291e-08.17 Page 9

Any interruption to the equipment grounding conductor

inside or outside the equipment, or disconnection of the

grounding conductor connection represent a danger to

you and the product. Intentional disconnection is not

permitted.

The power connector must only be connected to a

socket outlet which has a grounding contact. This

protection must not be removed by an extension cable

with no grounding connection.

Blown fuses must be replaced with the appropriate types

with the specified current rating. The use of "repaired"

fuses or short-

circuiting of the fuse holder is not

permitted.

The lug on the terminal at the rear panel is connected to

the power connector ground and can be used to

connect an common grounding conductor.

2.3 Electromagnetic Compatibility

well as the requirements for electromagnetic compatibility

according to EN 61006-6-3/4 (interference emission) and

EN 61000-6-1/2 (interference immunity).

To ensure that electromagnetic compatibility (EMC) is

maintained for the entire measuring chain, particular care

must be given to connection of the inputs and outputs of

the cable screen and to the cable installation:

 Do not install the cable in parallel with interfering con-

ductors.

 Use only screened cables.

 Ensure good connection between screen, connector case

and equipment case.

 Comply with EMC standards also on the machine side.

EMC and Ground Loops

Piezoelectric sensors are normally designed, so that one of

the electrodes is on the sensor case. When it is installed,

the sensor is usually grounded by the metal structure

(safety). The amplifier has separated input grounds of

channel A und channel B in order to prevent signal

interference. A differential amplifier stage prevent ground

loops between any input ground and the output ground.

3. Basic Concepts

3.1 Arrangement of SCP Measuring System for Engine Indication on

Test Stand

The measuring signals of the piezoelectric and piezoresis-

tive pressure sensors installed in the test engine are

transmitted by cable to the relevant amplifier modules of

the Signal Conditioning Platform. These convert the signals

to a voltage which is amplified to a standardized voltage

signal (±10 V). In a typical application, this voltage signal is

then further processed by a data acquisition unit.

To achieve maximum signal quality, the measuring signals

are conditioned in the SCP on a purely analog basis. Digital

signals are used only for setting parameters and to actuate

the measuring modules.

The individual SCP measuring modules have their para-

meters set or are actuated via a PC or a higher ranking

computer (Host) via an RS-232C interface.

stand

2853A_002-291e-08.17 Page 13

3.2 Arrangement of SCP Compact and SCP Slim Measuring System for

Mobile Engine Indication in Vehicle

The SCP Compact 2854A131 and the SCP Slim 2852A11

are designed specifically for mobile measurements, for

example in vehicles. In addition to their compactness these

versions of the SCP are differentiated by a (10 ... 36 VDC)

power supply.

3.3 Characteristics of the Signal Conditioning Platform

Special features and functions ensure that the SCP provides

the most accurate and reliable measuring results possible,

see following description.

3.3.1 SCP Installation Close to the Sensor

In order to minimize measuring errors due to interference

and the resulting parasitic charge transfers or interference

currents, the connecting cable between sensor and ampli-

fier input should be kept as short as possible. The SCP is

designed so that it can be installed and operated in the

immediate vicinity of the engine in the test stand cubicle.

All settings can be remote controlled from a PC with the

SCP software or from a higher ranking computer (Host).

Fig. 5: SCP installed close to the sensor

Use only low-noise cable between piezoelectric sensors

and the associated charge amplifiers. This is the only

way to ensure that noise is kept to an acceptable level.

The cables offered by Kistler provide optimized trans-

mission and signal quality, and guarantee precise signal

transfer.

Basic Concepts

2853A_002-291e-08.17 Page 15

3.3.2 Drift Compensation of the Piezoelectric Amplifier

Thermal charge transfers in the measuring element and

leakage current in the incoming leads and in the amplifier

lead to a gradual change in the measured value. This

change is called drift and, particularly if the load on the

engine changes or if uncooled sensors are being used.

During prolonged measurement this drift can lead to the

measured signal falling outside the charge amplifier's

output range of ±10 V.

This effect is largely eliminated electronically with specially

developed drift compensation. This allows measurement to be

performed for any length of time, even during engine

transients.

In its effect, drift compensation is comparable with high-

pass filter. However, switching drift compensation on does

not lead to pMax or PMI errors at excessively low speeds

as with the high-pass filter, as the function only

compensates for the drift and not the actual engine

pressure signals. For further details see capt. 3.3.2.1.

Fig. 6: Pressure measurement with and without drift compensation

Fig. 6 shows that with a compensated engine signal the

reference line remains on zero, compared to an

uncompensated signal that drifts in a negative direction.

Example: Drift with a Change in Load During Measure-

ment with Uncooled Sensor

When there is a change of load in the engine between

when the engine is in fired mode and when it is in unfired

mode, the combustion temperature changes. Fig. 7 shows

a measured curve with no drift compensation applied. The

signal drifts considerably.

Fig. 7: Measured curve without drift compensation

With drift compensation operating (Fig. 8), the measuring

signal does not drift. The rapid rise at the beginning of the

engine in unfired mode is recognized an erroneous signal

and compensated for after a delay.

3.3.2.1 Drift Compensation of Piezoelectric Amplifier Type 5064C...

The Type 5064C... eliminates the drift of a cylinder

pressure signal with a digital drift compensation function.

The signal from the charge amplifier is acquired digitally for

this purpose. The microprocessor calculates the drift over

recent cycles and extrapolates its trend. This anticipated

drift is then fed back into the input of the charge amplifier

as reverse current. This avoids falsifying either the phasing

or the amplitude curve of the cylinder pressure signal.

Correct indication values can be calculated from the signals

of the charge amplifier.

Digital drift compensation is applied in the speed range

from 100 … 20 000 1/min.

If drift compensation is not possible or if no combustion

cycles are detected, the module automatically switches the

charge amplifier stage to the “Short” or “Long” mode.

This is indicated by the fast flashing yellow LED in

Drco/Short mode and by a slow flashing yellow LED in

Drco/Long mode. The amplifier switches back to drift

compensation automatically when a combustion cycle is

detected.

For measuring cylinder pressure signals the amplifier can

always be operated with drift compensation switched on.

However, drift compensation cannot be applied to other

signals.

3.3.3 PiezoSmart® Automatic Sensor Identification

PiezoSmart automatic sensor identification is an active

system for identifying individual piezoelectric and piezo-

resistive pressure sensors and accelerometers. Based on the

IEEE 1451.4 standard, this system offers Plug & Measure

capability for automatic parametrization of measuring

chains.

Fig. 9: Sensors wth sensor identification and charge

amplifier

The heart of PiezoSmart is an electronic medium known as

TEDS (Transducer Electronic Data Sheet) integrated into

the plug of the sensor cable on the amplifier side. This

TRIAX plug and the pressure sensor together constitute a

physical unit. The size and shape of the TRIAX plug fits the

standard Kistler mounting tool for M5 miniature sensors.

As the plug with the TEDS does not need to be separated

from the sensor when the sensor is installed, clear and

unequivocal allocation of sensor data is ensured in daily

test stand operation.
