Cylinder Pressure Transmitter Type 6613CA
Page 4 6613C_002-026e-02.16
2. Description
2.1 Introduction
The pressure transmitter Type 6613CA contains a piezo-
electric sensor and an integrated charge amplifier. The
pressure transmitter is made for continuous cylinder
pressure monitoring of large gas engines.
Suitable for gas engines
Extremely long life due life time optimized design.
High reproducibility.
The sensor can be installed in the cylinder head, in the
indicator valve or underneath the indicator valve in a
additional adapter ring.
The integrated charge amplifier provides an uniform output
and can be connected directly to a data acquisition unit.
There are no individual sensitivity adjustments necessary,
since the output has uniform sensitivity. The sensor has a
voltage output of 0 ... 5 V with a zero line of 2 V (if
pressure is 0 bar). The output is ac – coupled, so static
pressure measurements are not possible.

2.3 Working Principle
The cylinder pressure is acting on the diaphragm. The
diaphragm converts the pressure in proportional force on
the sensor element. The piezoelectric sensor element
converts the force into a charge. The charge is converted
by a charge amplifier into a voltage.
The complete measuring chain is designed for easy
operation and very long life time.
The advantage piezoelectric principle is:
Operates safe up to high temperatures and therefore
ideally suited for accurate measurements in harsh
conditions.
Very small sensitivity change over temperature range.
High stiffness, results in small diaphragm stress
High reproducibility since the piezoelectric constant of
the measuring element is a constant of nature and
does not change over time.
The zero line output signal is about 2 V if there is no
pressure on the sensor. This allows a small drift of the zero
line of the transmitter output without cutting the signal
(Fig 4). These drift is the result of temperature fluctuation
caused by a quick load change of the engine. The ac –
coupling of the amplifier forces the zero line back to 2 V.

3. Installation
3.1 General
The quality of the measurement and the life time depends
very much of a correct mounting.
The mounting hole must be manufactured within the
tolerances
Avoid mounting at the end of long tubes, it creates
pipe ringing and overheating of the sensor
Ideal is a mounting hole in the cylinder head with
about 20 mm distance from the combustion chamber
Also acceptable is a mounting in or below the indicator
valve. Tube between indicator valve and cylinder head
must be as short as possible
Sensor must be tightened according the mounting
torque
If there are any question regarding installation please
contact Kistler.

3.2 Recommended Mounting
Fig. 6: Mounting bore for Type 6613CA
Mounting torque is 15 N·m
3.2.1 Sealing
A leakproof mounting of the sensor is essential to prevent
overheating of the sensor by leaking hot gases. Good
sealing is obtained by
fine-machined sealing face on the engine (for surface
roughness, flatness and squareness see fig 7).
all sealing faces (on engine and on sensor) must be
clean and free of any burrs.
3.2.2 Installing the Sensor
Clean all parts and apply a light film of grease to the thread
and the sealing surface. Use high-temperature paste MoS2
(e.g. Molycote P74 or 1 000) or copper grease.
Insert sensor into mounting bore an torque with 15 N·m.
Use a torque wrench for sensor mounting. After Installing
the sensor, check if there is no leakage if engine runs on
idle speed.
Installation
6613C_002-026e-02.16 Page 9
3.2.3 Installing the Charge Amplifier
Charge amplifier can be fixed with cable strips in the cable
channel. Select a location where the temperature does
certainly not exceed 110 °C. Route and fix the integrated
cable between sensor and preamplifier so it is protected
against mechanical damage. Keep it away from any source
of heat such as the exhaust or hot fuel lines.
3.2.4 Cable between Charge Amplifier and Data Aquisition Unit
This cable can be made by the user. The connector M12x1
on the charge amplifier is very common in industrial
application. Use a shielded cable, otherwise the sensor is
not conform with CE rules. The following connecting
cables are available from Kistler.

Calibration
In order to calibrate the Type 6613CA with a static pressure the time constant needs to be changed from
short (5 s) to long . This is done by connecting pin 3 to a voltage of 3 … 32 V.
The time for calibration must not exceed 15 s . For any questions please contact Kistler.

3.2.6 Special Hints for Spark-Ignited Gas Engines
Gas engines have extremely strong EMC-fields, which can
affect the transmitter signals. Please make sure that
resistance spark plugs are used, normally
the charge amplifier and the cable of the sensor, is
kept at least 150 mm away from any ignition cable or
coil.
the sensor cable and the ignition cable are not installed
in parallel if possible.

Page 12 6613C_002-026e-02.16
4. Operation
After starting up the engine check for any gas leakage at
once. If there is any gas leaking out, stop the engine and
rectify the mounting to achieve a complete sealing (see
chapter 4).
Warning: If the sensor is mounted in an indicator
valve: When the engine is operating do not open the
indicator valve for more than 10 seconds at a time as
otherwise the sensor may be overheated.
Maintenance
6613C_002-026e-02.16 Page 13
5. Maintenance
After installation, the transmitter needs no maintenance.
Do not use a steam or high-pressure cleaner for cleaning
purposes.
Calibration is recommended after one year of operation.
This can be done on the either with a dead weight tester,
or with the calibration equipment available from Kistler.
Please contact your Kistler representative for technical
consultation.
Never use wire brushes, screw drivers or any other sharp
pointed instrument for cleaning the diaphragm.
