Page 8: Operation
4. Operation 4.1 General information For pressure pulses up to about 500 bar, only the aluminum rod is used as drop weight (Kistler Material 65013682). For pressure pulses > 500 bar, the drop weight of 5,4 kg is used (Kistler Material 65013680). -
Page 9: Location
Pressure Pulse Generator 4.3 Location To obtain ideal operation, i.e. max. pressures, shortest pulse duration and good recoil of the drop weight, the pressure pulse generator must be set up on a flat and hard base (e.g. steel plate, concrete floor). Good recoil allows the weight to be caught again with the hand after the initial impact on the piston. -
Page 10: Supporting The Drop Weight
In order to protect the sensors against overload, the drop height of the 5,4 kg drop weight can be limited by clamping a circlip (Kistler Material 65013337) as a limit stop on the piston rod. ƒ Unscrew the 4 hexagon screws M4 in the drop tube cover ƒ... -
Page 11: Operating Faults, Notes
Pressure Pulse Generator 5. Operating faults, notes 5.1 Air inclusions Air inclusions in the pressure chamber cause pressure fluctuations during the pressure rise. Remedy: Dismantle the test sensor, top up with oil and screw the sensor back in as described in paragraph 4.2. Fig. - Page 12 Operating faults, notes Fig. 4: Pressure curve with leaking seal Type 1101B In order to obtain max. pressure pulses, the drop weight must slide smoothly in the tube. If there is a noticeable resistance in the movement of the drop weight, the piston must be lubricated with oil.
