Page 9: Principle Of Operation
Water cooled piezoelectric sensors 2.2 Principle of operation The sensor membrane converts the measured pressure into a force which is applied to the piezoelectric measu- ring element. In the piezoelectric crystal package this force generates an electrostatic charge proportional to the load. -
Page 10: Requirements To Water Cooling
Preface 2.3 Requirements to water cooling The use of cooling system Kistler Type 2621 is highly recommended. It is capable of supplying up to ten water cooled piezoelectric sensors (depending on the heat load created by the application) with the optimum quantity of water, at the right pressure and constant temperature. - Page 11 Water cooled piezoelectric sensors If the water cooling system fails and cannot work normally, the engine and water cooling system should be shut down immediately to prevent the water cooling system from working intermittently, thus damaging the sensor. To con- tinue using the water cooling system, stop the engine until the temperature of the piezoelectric sensor drops to ap- proximately the same temperature as the coolant.

Page 12: Installation Of The Piezoelectric Sensor
Installation of the piezoelectric sensor 3. Installation of the piezoelectric sensor 3.1 General information The accuracy of a measurement and quality of the data are highly dependent on careful installation of the piezo- electric pressure sensor. The sensor bore must be machined to the specified tole- rances. The specified tightening torque of the piezoelectric sensor must be observed. 3.2 Direct installation Direct installation requires the least installation space. -
Page 13: Installation Examples
Water cooled piezoelectric sensors Benefits of using a mounting sleeve: ƒ Precise sensor bore inside the sleeve ƒ Machining of the bore for the mounting sleeve is simplified ƒ The mounting sleeve has the required strength to en- sure that the sealing part can resist wear. This allows the sensor to be mounted and dismounted repeatedly without restrictions ƒ... -
Page 14: Machining The Mounting Bore
Installation of the piezoelectric sensor 3.5 Machining the mounting bore When preparing the sensor bore, ensure that the thread is concentric in relation to its individual steps. The sealing part must be completely flat. Refer to the specifications and tolerances stated on the datasheet of the sensor. All machining steps with the drill, milling cutter, reamer and screw tap must be performed with the work held se- curely in the same position. -
Page 15: Check Points Before Installation
Water cooled piezoelectric sensors 3.7 Check points before installation ƒ Water leakage - After connecting the rubber hoses to the cooling pipes of the sensor, operate the cooling system and check that there is no leakage ƒ Piezoelectric cable - If the piezoelectric cable connec- ted to the sensor is loose it must be retightened. -
Page 16: Installing The Sensor Into The Bore
Installing the sensor into the bore 4. Installing the sensor into the bore Feed the piezoelectric cable and both rubber hoses through the mounting wrench, and then fit the mounting wrench on the hex of the sensor. If you are using the slot- ted mounting wrench Type 1300A73 for sensor Type 6041, pay attention to proper positioning of the piezoelectric cable and rubber water hoses in the slot (otherwise... -
Page 17: Piezoelectric Sensor Cable Routing
Water cooled piezoelectric sensors 5. Piezoelectric sensor cable routing The piezoelectric cable of the sensor must be routed to avoid other high-frequency, or power cables, as much as possible, e.g. ignition or fuel injection system cabling, dynamometer or motor power cables. If this cannot be avoided, the piezoelectric cables should be kept perpen- dicular to the high-frequency signal lines to reduce signal interference. -
Page 18: Setting Up The Measuring Chain
6.2 Selecting the sensor sensitivity Since Kistler water cooled sensors can be used with wa- ter cooling or uncooled, the sensitivity at 50 °C should be used if water cooling is used, and the sensitivity at 250 °C should be used in the case of uncooled operation. -

Water cooled piezoelectric sensors 7. Dismounting and maintenance 7.1 Dismounting Allow the cylinder head to cool down before removing the sensor from the mounting bore. Dismount in reverse order than installation: ƒ Switch off the water cooling system ƒ Disconnect the water hoses of the sensor from feed and return manifold ƒ... - Page 20 10E13 Ω.
