Page 9: Operation In Potentially Explosive Environments
Operation in potentially explosive environments 3. Operation in potentially explosive environments For proper operation, it is necessary to first determine whether the sensor will be installed in hazardous area. The cylinder pressure Sensor type 6635AX is marked for application only in zone 2 Category 3 systems. Type of protection: SEV 18 ATEX 0115 X II 3G Ex nA IIC T3 Gc... -
Page 10: Labelling
Cylinder pressure sensor, Type 6635A1 4. Labelling The cylindrical pressure sensor is labeled with the ATEX and IECEx designation. The ATEX marking is laser marked on the amplifier housing and is non-removable. Made by Kistler Instrumente AG Winterthur, Switzerland Type 6635A1 SN1234567 Device rated 32V DC;... -
Page 11: Description
Description 5. Description 5.1 Introduction The cylinder pressure sensor consisting of a life time optimized piezoelectric pressure sensor linked by a robust fluoropolymer cable to a charge amplifier. The rugged design and high temperature resistance allows for flush mounting and enables reliable knock detection. The sensor can be installed by using shoulder sealing. -

Page 13: Working Principle
Description 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 current. The complete cylinder pressure sensor is designed for easy operation and very long life time. -
Page 14: Installation
Cylinder pressure sensor, Type 6635A1 6. Installation 6.1 General The quality of the measurement and the sensor lifetime depend very much on the correct mounting of the sensor. The mounting hole must be manufactured within the tolerances. Avoid mounting at the end of long tubes, it creates ... -
Page 15: Sealing
Installation 6.2.1 Sealing A leak proof mounting of the sensor is essential to prevent overheating of the sensor by leaking hot gases. Good sealing is obtained by fine-machined sealing surface on the engine (for surface roughness, flatness and perpendicularity) all sealing surfaces (on engine and on sensor) must ... -
Page 16: Bandwidth As Function Of Load Capacity
Cylinder pressure sensor, Type 6635A1 6.2.6 Bandwidth as function of load capacity High capacitive load from the cable between the sensor and the data acquisition unit, as well as a high input capacity of the data acquisition unit can affect the sensor bandwidth. -
Page 17: Operation
Operation 7. 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 6). Warning: If the sensor is mounted in an indicator valve: When the engine is operating do not open the indicator valve for more than one working cycle as otherwise the sensor may be overheated. -
Page 18: Maintenance
Cylinder pressure sensor, Type 6635A1 8. Maintenance After installation, the sensor needs no maintenance. Do not use a steam or high-pressure cleaner for cleaning purposes. Never use wire brushes, screw drivers or any other sharp pointed instruments for cleaning the diaphragm. -
Page 19: Trouble Shooting
Trouble shooting 9. Trouble shooting In case the sensor does not give a proper output signal, please disconnect the cable for a couple of seconds and connect it again. The amplifier works with a so-called time constant to ensure a reliable signal without drift. Due to the time constant, the sensor may be out of range for a short period of time. -
