Page 16: Quality Of Mounting Bore
Piezoelectric Pressure Sensor Type 6239A… 4.2.3 Quality of mounting bore 4.2.3.1 Faulty sealing surface An uneven or concave sealing surface (Fig. 10) will impede a proper sealing function. If an excessive tightening torque is applied repeatedly, the sensor may also dig into the sealing surface preventing uniform pressure distribution over that surface. - Page 17 Installation and operation Fig. 12: Surface finishing tool Type 1300A46A1 (M10x1 thread) or 1300A25A1 (3/8-24 UNF thread) Fill the grooves of the cutting surfaces with special lubricating grease Type 1063 (supplied). The grease picks up the chips, preventing them from becoming jammed between cutter and sealing surface.

Page 19: Sensor Installation And Removal
Installation and operation Sensor installation and removal 4.3.1 Installation During the installation of sensor Type 6239A... the sealing ring 1100A105 has two functions. First, it seals and avoids gas evasion and pressure loss through the thread. Second, for tangential shot shell pressure measurements the rings are used to adjust the distance of the sensor from the cartridge (see section 6.1.1). - Page 20 Piezoelectric Pressure Sensor Type 6239A… Fig. 18: Insert the sealing ring. For every additional sealing ring, two additional dots of grease must be applied. Fig. 19: Apply grease to the sensor thread to facilitate insertion. Check the mounting bore for any remaining sealing rings from the previous installation.

Page 21: Tightening
Tightening torques >15 N·m may damage the sensor (plastic deformation and mushrooming of the shoulder part). Kistler recommends dial type torque wrenches such as Kistler Type 1371B to prevent application of excessive torque. Fig. 21: Torque wrench Type 1371B can be used to apply a precise mounting torque. -

If the leakage persists, inspect the sensor shoulder and mounting cavity for damaged sections. 4.3.3 Cabling Cables should be routed to avoid tension, kinking, and sharp bends, particularly at the connectors. Restrain cables by tying, taping or clamping in highly vibrating environments so as to avoid mechanical damage. -
Page 23: Maintenance And Calibration
Fine cleaning: for fine cleaning it is recommended to dip the sensor in a cleaning agent based on mineral oil (e.g. petroleum ether, petrol), wipe it with a paper towel and apply Kistler cleaning spray Type 1003. Repairs shall only be conducted by Kistler. 5.1.2 Connectors... - Page 24 However, never use air-blast to clean the connectors. It will unavoidably deposit a film of water vapor. Instead, Kistler strongly recommends the use of cleaning spray Type 1003. Please contact your local sales center, should drift or measurement of low insulation persist after cleaning all connectors.

Page 30: General High Pressure Measurement
Piezoelectric Pressure Sensor Type 6239A… General high pressure measurement For general high pressure applications, the recess mounted setting has an advantage over the flush mounted setup, as the sensor membrane is protected from the effect of high flash temperature and particle hit, due to the passage hole. -
Page 31: Influence Of Long Measuring Bore
Various measuring arrangements 6.3 Influence of long measuring bore A passage (measuring) hole length of 3 ... 5 mm is ideal, since no disturbing gas vibrations occur in a hole of this length. Long measuring bores act like a low-pass filter. Low frequencies are measured free of error.
